外文资料Celebrate Your Freedo m from Allergens-- The #1Rated Whole-House Air Purification SystemAbstractThe Perfect 16 powerfully removes more allergens, bacteria, dust, pollen and other airborne contaminants that are detrimental to your health. It’s the perfect system for people who suffer from allergies, asthma or for people who simply want to breathe the cleanest air possible. Let IQAir transform your house into a healthy home.Key word：The Perfect 16；Remove allergens；Fresh airHighest Efficiency – Lowest Air RestrictionThe Perfect 16™ is the only system that is rated a perfect Merv 16, the highest filtration rating possible. MERV stands for Minimum Efficiency Reporting Value. The MERV system was created by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) to independently verify how well an air filtration system really cleans the air. Until the Perfect 16, no residential whole-house air cleaning system had ever achieved this ultra-high rating.While efficiency is very important, low air restriction is equally important. Conventional whole-house air cleaners can decrease the airflow of your central heating and air conditioning system by as much as 50%. As a result, the forced air system has to work harder and longer to cool or heat your home. Increased energy consumption adds to your monthly electricity bill. In contrast, the Perfect 16 has the highest filtration efficiency coupled with one of the lowest air restrictions* in the industry. In fact, it actually improves the performance of your heating and air cooling system when when compared to conventional air cleaners.Seamless IntegrationUnlike other air cleaning systems, the Perfect 16 is seamlessly retrofitted into your home’s existing heating and/or ai r conditioning system. It cleans 100% of the airin your home. No partial cleaning or limited bypass installation.Air is drawn through your home’s return grill typically located in a common area such as a hallway, then filtered through pleated micro-fiber filtration panels. This traps harmful micro-particles each and every time the air circulates through the system.Purified air goes through your central air handling unit where it is distributed to every corner of your home. The air in your house gets filtered through this system up to 125 times per day. The Perfect 16 continuously cleans and purifies the air to transform your house into a healthy home.In 1963, the brothers Klaus and Manfred Hammes introduced the world’s first residential air cleaner. It was designed to help people who had coal burning stoves remove dust and soot from the air. Soon they discovered that people who had their air cleaners were experiencing better health. Manfred, a life-long allergy and asthma sufferer, was the first person to benefit from his own machine.Swiss Craftsmanship The Highest QualityCrafted, assembled, individually inspected and tested at IQAir’s Swiss factory, each Perfect 16 meets our high standards before it leaves our facility. IQAir expert craftsmen construct each unit with dedication and extreme attention to detail.IQAir’s passion for the highest product quality extends to our expert, professional installation practices.IQAir leads the industry with the most comprehensive installation guarantee.The Perfect 16 Delivers up to 50 Times More Filtration PowerThe Secret is the Revolutionary V2 DesignThe V2 Difference: Perfect 16’s revolutionary V2 designMost air filters have a single flat surface that fits squarely into the housing of the syst em. The Perfect 16’s filters are placed in a double “V” shape. The V2 design allows the Perfect 16 to use over 170 square feet of filter media. This is up to 50 times more filtration material than that of ordinary filtration systems. The additional surface area creates higher filtration efficiency, while allowing more air to pass through the system. A truly innovative design with substantially increased collection area providessuperior filtration power over ordinary filtration systems.Featuring Unique AMF TechnologyThe Perfect 16 is the first whole-house air cleaning system to utilize advanced micro-fiber filtration technology. Filter fibers are 10 times thinner than those used in standard air filters. This allows air to easily pass through the filters, while the ultra-fine threads create an almost impenetrable barrier for pollution particles. The result is an air filter that sets a new standard for air cleaning efficiency as well as airflow.No Filter Replacements for 3 Years!Most whole-house air cleaning systems and furnace filters require monthly changing and many even require weekly cleaning. The Perfect 16 takes the worry and hassle out of frequent filter changes and servicing.The Perfect 16’s extra large filter surface area is so efficient and long lasting that you won’t need service or replacements for up to three full years.Our 10x Cleaner Air GuaranteeThe Perfect 16 is the only whole-house air purification system that is backed by an industry-leading performance guarantee. We promise you an over 90% reduction of airborne allergens and pollutants -such as dust, mold spores, bacteria, and viruses -or your money back! As part of the IQAir tradition of air cleaning excellence, each Perfect 16 is tested at the IQAir Swiss-based factory before it is shipped to our customers to ensure optimum performance. But now we’re taking this tradition to the highest level and going beyond industry standards by testing the system and guaranteeing the results right in your home.After the Perfect 16 is installed, the IQAir Authorized Installer will test and verify the installation with an advanced laser particle counter. The authorized installer will ensure that the system is removing at least 90% of particles 0.3 microns or larger. System performance will b e detailed in a personalized owner’s certificate.Using advanced laser technology, an IQAir Authorized Installer will test particle levels before and after installation to guarantee results of 10X cleaner air. After testing the system, our IQAir Authorized Installer will enter the test results intoa personalized owner’s certificate which certifies your home as one of the healthiest homes in America.IQAir’s Whole-House Air Cleaning System Wins Reviewboard’s Product of the YearWritten by Philip Ferreira, Editor-in-Chief of Reviewboard MagazineThe home we tested the Perfect 16 in was immaculate, but like many homes it had a hidden problem –unhealthy indoor air. We used advanced laser particle counting equipment before and after installation so that our readers could see what they could really expect if they had this system installed in their own home.The Perfect 16 delivers the highest level of air cleaning effectiveness available to homeowners. Reviewboard tested the system in a real home, not in a laboratory, and we saw an almost 95% improvement in air quality.The Perfect 16 retrofits into existing heating and/or air conditioning (HV AC) systems. It uses the existing duct work of a home to provide clean air to every room of the house. The Perfect 16 utilizes IQAir’s Advanced Micro-Fiber Filtration technology. The ultra-fine fibers used in the Perfect 16’s filters are ten times thinner than the fibers used in standard air filters. This allows air to pass easily through the filter mesh while creating an almost impenetrable barrier for common household pollutants like dust, pollen, mold spores, allergens, even bacteria and viruses.We also noted that the Perfect 16 does away with a major annoyance of other whole-house air purifiers: frequent cleaning or filter changes. Most air purifier systems require cleaning or filter changes every few months.The Perfect 16 is filter replacement and maintenance free for up to three years. The Perfect 16 utilizes the circulation of a home’s forced air HV AC system. It does not require additional electricity to operate, and unlike electronic air purifiers, it produces absolutely no ozone.The Perfect 16 is a truly amazing product. In our judgment, it is the best whole-house air purification system on the market. It is exceptional in its air cleaning effectiveness and ultra-low maintenance. It’s a true winner and deserving of Reviewboard’s Product of the Year award.The Perfect 16 can be seen Sundays on ABC’s popular television show “Extreme Makeover: Home Edition”, as IQAir helps the show’s Design Team build healthy homes for deserving families. It is also currently featured in “Esquire House 360” in Beverly Hills, California.About Reviewboard –Alexa ranking lists Reviewboard Magazine as the third largest consumer product review publication in the world. Their product reviews are read each year by more than 110 million readers in 54 countries worldwide. Alexa also lists Reviewboard as the #1 user ranked consumer publication in the world.Real Homes - Real ResultsWhat difference will the Perfect 16 make in your home? Take a look at the results achieved in this old home built in 1928. It is hillside property in Los Angeles, a city known for its poor air quality. Indoor air quality specialists used advanced laser pa rticle counters to measure the home’s indoor air quality before and after the installation. The instruments recorded the microscopic airborne pollution particles in the home including dust, mold, pollen, bacteria, and other irritants.This home’s air qual ity was improved by over 95% within 90 minutes of installation, and that’s a typical result.Location: Los Angeles County, California | Home size: 2’300 sq.ft (two story). Date: June 24, 2006 | HV AC System airflow: 1200 cfm Air Cleaning: Perfect 16 ID-2225Before the installation the air pollution levels throughout the home were at approximately 1.5 million particles per cubic foot. After the Perfect16 was installed, the air quality was improved by over 90% in just 60 minutes. After 90 minutes, air quality was improved by over 95%. The home went from an unhealthy indoor environment to one of America’s cleanest homes in just an hour and a half. These are real results achieved in real homes, the kind of results you can expect when your Perfect 16 is installed.2000-2008 The IQAir Group. All rights reserved.

空气净化器工作原理详解
空气净化器工作原理详解空气净化器是一种能够净化室内空气，去除空气中的污染物的设备。
它能够有效地去除室内空气中的细颗粒物、有机化合物、异味、病毒、细菌等有害物质，提高室内空气的质量。
那么，空气净化器是如何实现这一功能的呢？本文将详细解释空气净化器的工作原理。
一、过滤净化原理空气净化器主要通过过滤的方式去除空气中的污染物。
它内部通常配置了多层滤网，每层滤网的材质和功能都不相同。
最常见的滤网包括预过滤网、活性炭滤网和HEPA滤网。
空气首先通过预过滤网，该滤网能够去除空气中的大颗粒物，如灰尘、毛发等。
然后通过活性炭滤网，活性炭具有吸附性，可以去除空气中的异味和有机化合物。
最后，通过HEPA滤网，HEPA滤网能够有效过滤掉室内空气中的细颗粒物，如PM2.5、花粉等。
经过这层层过滤，空气中的污染物得以去除，空气质量得到改善。
二、臭氧杀菌原理除了过滤净化外，一些空气净化器还可通过臭氧杀菌来提高空气质量。
臭氧是一种氧化性强的气体，可以破坏细菌的细胞壁，达到杀菌的效果。
臭氧杀菌主要通过电离、紫外线等方式生成，然后释放到空气中。
臭氧杀菌能够有效消灭空气中的病毒、细菌等微生物，净化空气中的微生物污染物。
三、电静力吸附原理除了通过过滤和臭氧杀菌，还有一些空气净化器采用电静力吸附原理去除室内空气中的污染物。
电静力吸附是指利用静电吸附原理将空气中的颗粒物吸附在电极上。
这种技术可以有效去除空气中的颗粒物和细菌，提高空气质量。
四、负离子净化原理负离子是一种带负电荷的氧分子，能够与空气中的微小颗粒物相吸引，形成较大的颗粒物。
通过负离子的作用，空气中的细颗粒物增大，从而更容易被过滤掉。
负离子净化技术可以减少空气中的细颗粒物，改善空气质量。
五、紫外线杀菌原理一些空气净化器还可以采用紫外线杀菌原理来净化空气。
紫外线能够破坏微生物的DNA结构，从而杀灭微生物。
通过紫外线杀菌，可以有效地消除空气中的病毒、细菌等有害微生物。
综上所述，空气净化器的工作原理主要包括过滤净化、臭氧杀菌、电静力吸附、负离子净化以及紫外线杀菌等。

31KAX电子空气净化器说明书
Model 31KAX Electronic Air CleanerA GUIDE TO OPERATING AND MAINTAINING YOUR ELECTRONICAIR CLEANERNOTE TO INSTALLER: This manual should be left with the equipment owner.®Thi dtt d ith FM k404A BREATH OF SPRING-FRESH AIR . . . YEAR-ROUNDCongratulations on your excellent choice and sound investment in this addition to your home comfort system.Your electronic air cleaner represents both the latest in engineer-ing development and the culmination of many years of experi-ence from one of the most reputable manufacturers of comfort systems.Your new unit is among the most energy-efficient and reliable air-filtration products available today. To assure its dependabil-ity, spend just a few minutes with this booklet now. Learn about the operation of your electronic air cleaner and the small amount of maintenance it takes to keep it operating at peak efficiency. With minimal care, your electronic air cleaner will provide you and your family with clean, spring-fresh air — from season to season, and year to year.YOUR ELECTRONIC AIR CLEANING UNITMORE THAN JUST A BREATH OF FRESH AIRThe highest value of clean air is in its contribution to the good health and comfort of you and your family. Additional benefits include potential savings in home heating, cooling, and mainte-nance costs.Your new air cleaner will electronically filter out microscopic particles as small as 0.01 micron. At that size, it would take 100,000 particles to cover the head of a pin. Such particles are 500 times smaller than the smallest grains of dust trapped by conventional furnace filters.Airborne pollutants commonly found in the household are lint, dust, ash, pollen, fungus spores, bacteria, viruses, cooking odors, fumes, and possibly tobacco smoke.By ridding your home of most of these pollutants, the whole family can breathe fresher, safer air. Moreover, family members suffering from hay fever, asthma, or other respiratory allergies should find exceptional relief. Electronic filtering removes up to 95% of all pollens.If your home is equipped with central air conditioning or a heat pump, electronic air cleaning can optimize your system’s per-formance by keeping the indoor coil clean. At today’s energy rates, the potential savings can be significant.Electronic air cleaning removes most airborne grease and grime particles before they have a chance to settle. Therefore, walls, win-dows, draperies, and furnishings stay clean and bright longer. The time and money you save from avoidable cleaning and redecorat-ing projects can be dedicated to more rewarding goals.HOW YOUR AIR CLEANER WORKSContaminated air enters the prefilter (the metal mesh filter) where the larger airborne particles are removed. These include hair, fibers from carpets and drapes, pet hair, and some lint par-ticles. (See Fig. 1a.)The air then passes through the ionizer/collector cells. The ion-izer wires produce positive ions that give airborne particles a positive electrical charge. (See Fig. 1b.)Opposites attract: Airflow continues, passing between the col-lector plates. The positively charged particles are attracted and trapped by the negatively charged collector plates. (See Fig. 1c.) These particles continue to cling to the plates until removed by you or your service technician.Meanwhile, the purified air leaves the air cleaner, refreshingly free of contaminants. This clean air is circulated into your living space by your heating and cooling system providing clean air for breathing into your lungs. (See Fig. 1d.)DUCT-TYPE ELECTRONIC AIR CLEANER (EAC) The DUCT-TYPE EAC is well suited for home comfort systems using a gas furnace, split-system air conditioner, or split-system heat pump. If yours is a DUCT-TYPE cleaner, it is installed near your furnace or split-system air handler. See Fig. 2 for typical installations of a duct-mounted air cleaner.Fig. 2—Typical EAC InstallationsCLEANAIRCLEANAIRFig. 1—Air Cleaner Processa b c d23OPERATING YOUR ELECTRONIC AIRCLEANERYour new electronic air cleaner is designed to operate as part of your heating/cooling system. After the cleaner’s power switch is turned ON, the cleaner will operate whenever the furnace or air-handler blower is running.Your electronic air cleaner will perform at maximum efficiency if these recommendations are followed:• Consider running the heating/cooling system blower contin-uously—day and night, winter and summer. Continuous blower operation provides for constant air filtration. It may also contribute to greater personal comfort since continuous blower operation minimizes temperature differences through-out the home.Fig. 3—ThermostatFurthermore, systems equipped with humidifiers offer the added benefit of having the air humidified during heating.• Supply-air and return-air grilles should not be blocked. Drapes,furniture, and toys are some of the items commonly found ob-structing grilles. Restricted airflow reduces the efficiency of the air cleaner, as well as that of the whole comfort system. • The electronic air cleaner must be properly maintained.START-UP PROCEDURES1. Set the temperature control selector on your indoor thermo-stat. Choose a setting above current room temperature if heating is required. Set the temperature control selector below room temperature if cooling is needed.2. Set the FAN mode. When set to AUTO, the air cleaner and system blower will run only while the thermostat operates the heating or cooling section. When the FAN mode is set at the ON position, the air cleaner and blower will run continuously—re-gardless of whether the cooling or heating section is operating.3. Select HEA T, COOL, or AUTO.4. Turn the air cleaner’s power switch ON. The power switch for the DUCT-TYPE cleaner is located on the door panel. (See Fig. 4.)®Fig. 4—Power Switch AccessNOTE: The operation light indicates that power is available to the cells. It does not indicate that power is available to the unit. NOTE: An occasional arcing (snapping) noise is normal during the operation of your air cleaner. Continuous arcing, however,indicates that cleaning is required. Refer to page 4 for directions on cleaning your electronic air cleaner.ELECTRICAL POWER DISCONNECT PROCEDURETo disconnect the electrical power to your air cleaner, sim-ply push its power switch to the OFF position. You may con-tinue to operate the rest of your comfort system, or turn the power off according to the manufacturer’s specifications.PERFORMING ROUTINE MAINTENANCEWith the proper maintenance and care, your electronic aircleaner will operate economically and dependably. Maintenance can be accomplished easily by referring to the following direc-tions. However, before performing any maintenance, consider these important safety precautions:• DISCONNECT ALL ELECTRICAL POWER TO THE AIR CLEANER BEFORE PERFORMING ANY SERVICE OR MAINTENANCE.NOTE: THERE MAY BE MORE THAN 1 ELECTRICAL DISCONNECT SWITCH.•ALTHOUGH SPECIAL CARE HAS BEEN TAKEN TO MINIMIZE SHARP EDGES IN THE CONSTRUCTION OF YOUR UNIT, BE EXTREMEL Y CAREFUL WHEN HAN-DLING PARTS OR REACHING INTO THE UNIT.The prefilter and ionizer/collector cells should be checked reg-ularly. Accumulated dirt will need to be removed from these components to maintain efficient air filtration.Regular inspection allows you to determine the cleaning schedule best suited to your home’s operating conditions. The first electronic cleaning of your home may collect more par-ticles over a shorter period than will be normal for future operation.4At minimum, the prefilter and collection cells will need to be cleaned two or three times per year.CLEANING PROCEDURES1. Turn OFF all electrical power to the air cleaner and furnace,split-system air conditioner, or split-system heat pump.2. Open the air cleaner.• In a DUCT-TYPE cleaner, rotate the fastener knob counter-clockwise until the door is released. Remove the door by grasp-ing the fastener knob, then lift up and away from the cabinet.(See Fig. 5A.)• The DUCT-TYPE prefilter simply slides out. (See Fig. 5b.)Fig. 5—Opening the EAC3. Clean the prefilter. Use a vacuum cleaner and soft brush attachment to remove accumulations of dust and lint. If further cleaning is required, wash the prefilter with mild detergent and water (or use pressurized spray from a garden hose or coin-operated carwash sprayer). Rinse. Then drain excess water from the prefilter. Thorough drying is optional.4. Remove the ionizer/collector cells from the air cleaner cabinet.• The DUCT-TYPE cells simply slide out of the cabinet.5. Wash the ionizer/collector cells either manually or in an automatic dishwasher. Complete drying of the washed cells is optional.• For MANUAL W ASHING, fill a large container with hot water.Add one-half cup of mild detergent for every 10 gallons of water used. Submerge the cells in the soapy solution and allow to soak for 20 minutes. Rinse with a garden hose or soak in clean, hot water for 10 minutes. Allow excess water to drain from the cells. • For a more convenient method, you may wash the cells in an AUTOMA TIC DISHW ASHER. Place the cells on the lower rack of the dishwasher. Be careful not to damage wires or bend plates. Be sure the airflow direction arrows point up. Add a de-tergent specifically formulated for automatic dishwashers. Al-low the dishwasher to run through a complete wash and dry cycle. Give the cells time to cool before removing from the dish-washer. Allow any excess water to drain from cells.6. Inspect the cells. Check for broken wires, dislocated wire holders, or bent collector plates. If everything appears to be fine,proceed to the next step. However, if any damage is suspected,contact your servicing dealer for immediate repairs.7. Reassemble your air cleaner. Insert the prefilter on the enter-ing air side of the air cleaner. Install the ionizer/collector cells.Be sure airflow direction arrows point away from where the pre-filter is positioned.ab8. Turn on the electrical supply power to your furnace, split-system air conditioner, or split-system heat pump.NOTE:No drying period is needed for the prefilter and cells before reassembly. However, the indicator lamp will not glow and the unit will not begin to operate until thoroughly dry.• Check the setting on your indoor thermostat. The FAN should be set at ON for continuous blower and air cleaner operations,or AUTO if you wish the blower and cleaner to function only when heating or cooling is required. • Check the power switch on your electronic air cleaner. Be sure it isON and the power indicator lamp is glowing.• Check the main power disconnect switch. V erify that the circuit breakers are ON or that fuses have not blown. If you must reset breakers or replace fuses, do so only once. Contact your servic-ing dealer for assistance if breakers trip or fuses blow a second time.• Check air cleaner components. Check for proper orientation of the prefilter and ionizer/collector cells. The prefilter must be on the incoming-air side of the cells. Arrows stamped on the sides of the cells must point in the direction of airflow. The prefilter and cells must be clean and dry.• Check for sufficient airflow. Check the air cleaner’s prefilter and ionizer/collector cells for any accumulation of dirt. Check for blocked return-air or supply-air grilles. Be sure grilles are open and unobstructed.If your comfort system still fails to operate, contact your servic-ing dealer for troubleshooting and repairs. Specify your apparent problem, and state the model and serial numbers of your equip-ment.With this information, your dealer may be able to offer helpful suggestions over the phone, or save valuable time through knowledgeable preparation for the service call.REGULAR DEALER MAINTENANCEIn addition to the routine maintenance that you perform, your electronic air cleaner should be inspected regularly by a properly trained service technician. The inspection (preferably each year,but at least every other year) should include the following:• Routine inspection of the prefilters and ionizer/collector cells. Clean, if necessary.• Routine inspection of ionizer wires. Service should include realignment or replacement as required.• A check of all electrical wiring and connections.• Operational check of the complete comfort system to deter-mine actual working condition.

空气净化器与新风净化器的区别有哪些
空气净化器与新风净化器的区别有哪些国内的雾霾天气日益增多，其中一线城市的雾霾天气尤为严重，空气质量问题不断地得到大众的重视，空气净化器在几年前开始陆续进入人们的家里。
多年使用空气净化器下来，发现了空气净化器的不少不足的地方。
空气净化器工作原理：传统空气净化器分为两个主要部分：风机和滤芯。
风机会把机器周围的空气抽入净化器内，气流通过滤芯的过滤后输出到室内，形成了气体净化的过程。
在实际使用中，需要注意的地方如下:空气净化器不可以紧紧靠墙体放置在空气净化器周围需要有空气进入，将机器放置角落，会影响进风口的气流而大大降低了净化的效率。
再者，放置在房间的角落位置会吸附角落里的脏东西，而影响净化器的正常使用寿命。
机器需要在距离墙体1~2米的距离放置，才会达到最高效的净化效果；需要定期更换滤芯空气净化器在使用过程中需要结合实际使用情况来决定更换滤芯的频率。
一年中使用空气净化器没有几次的情况下，不需要频繁的更换滤芯，以免造成滤芯的使用率没满而丢弃的浪费。
但是雾霾天气的日子比较多的情况下，必须密切留意滤芯的使用情况。
在滤芯被完全污染的时候及时更换滤芯，若更换不及时，在滤材吸附饱和之后会逆释放出有害物质，反而变成室内的“污染源”；千万不要加湿器与空气净化器配合使用净化器在使用的时候，滤芯滤材的净化会降低室内的湿度。
有不少用户会在净化器使用的时候，在旁边放置加湿器。
但是有使用过的用户都会知道，空气净化器和加湿器一起使用的时候，空气净化器会出现警报提示；门窗紧闭的情况下很容易造成室内供养很多用户在使用空气净化器的时候，会长时间关闭门窗。
担心室内已经净化的纯净空气跑到外面，而外面的污染空气进入室内。
关门窗开启空气净化器一段时间，室内空气的PM 值确实降下来，但是同时室内的氧含量也随着降下来。
空气中正常含氧量为21％,当氧含量缺少时,就会导致人员窒息。
根据相关研究报告表示，室内氧含量不足时，人体会有以下不适症状：室内含氧量低与正常数值时，人员需要离开房间并开窗通风，开窗通风时，室内的PM2.5会上升，等氧含量上去后再关窗并打开空气净化器。

fresh air空气净化器之风机解析
滤网可以说是空气净化器达成净化作用的关键元件，但滤网过滤是一种被动过滤，即滤网并不能主动吸收周围的颗粒物和气态污染物，还需要一个“搬运工”负责搬运空气通过滤网，这个重要的“搬运工”就是风机。
风机是空气净化器达到净化效果的动力，风机的选择和设计，会直接决定一台空气净化器的风量和净化效果。
不了解空气净化器的人可能会想，“空气净化器不就是在风扇前面加上片滤网嘛”，也有很多人按照这样的方法自制空气净化器，但效果往往不尽如人意，平时感觉风很强劲的风扇加上滤网后只能吹出很微弱的风。
真正的空气净化器的风机到底应该是什么样的呢？为解决这个问题，首先需要了解风机的种类和特点。
一、风机类型
风机的主要结构部件是电机、叶轮、机壳、进风口、支架等。
生活中常用的大部分是叶片式风机，叶片式风机根据气体流动方向的不同，可以分为轴流风机、离心风机和混流风机。
轴流风机：风的流向和轴的方向一致，特点是风量大，风压低。
离心风机：进风方向和轴流风机相同，但出风方向和轴流风机相垂直，靠产生的离心力来对空气做功。
风量大，适用于通风换气等流量要求高的场所。
混流风机：结合了轴流以及离心风机的特点的一种的风机，性能适中，其风量高于离心、风压大于轴流。
二、风机的选购要素
1、风阻
风机是空气净化器的矛，如果将风量比作一把武器的挥击力量，那么风压就是把这武器的锋利程度。
空气净化器不同于风扇，风扇的目的是产生风，而空气净化器的目的不是产生风，而是过滤空气中的污染物。
但是空气净化器的过滤能力不是由风机决定而由滤网决定，滤网对风又有非常大的阻力，如果风机的压力不足，就无法穿透滤网，那么就不可能产生任何洁净空气了。
F8级别的滤网只能算高中效滤网，但只要一片F8滤网就可以使一台家用的电风扇的风速减少到接近于零，即普通家用规格的风扇产生的风几乎无法穿透F8，更不用说一般的空气净化器还会配置风阻更大的H10以上级别的滤网并有多层滤网过滤。
所以，风压很低的轴流风机基本无法实现空气净化的重任，这也是很多DIY爱好者，即使使用和正常空气净化器差不多功率和大小的电风扇改造成简易空气净化器，其效率却远远低于专业空气净化器的原因。
混流风机有一定的风压，在排风降温方面效率很高，有不错的应用，但其面对滤网的的强大阻力，能产生的风压还是有所不足。
而离
心风机的风压很大，可以使空气穿透高阻力的滤网，噪音也相对较小，最适合用于空气净化器。
综上所述，空气净化器不仅考虑风量，更重要的考虑是如何克服阻力穿透滤网。
因此，空气净化器的风机对风压有很高的要求。
2、隐患问题
风机在使用过程中会存在电机过热的隐患，如何消除隐患？如何消除风险？跟风机选择和要求有关。
空气净化器的作用就是过滤颗粒物，随着滤网逐渐变脏，风阻会逐渐增大。
刚开始使用的时候，总风阻等于滤网的初始风阻。
随着使用时间变长，总风阻会变大，因为总风阻等于滤网的初始风阻加污染物的风阻。
当滤网报废时候，最终阻力一般是初始阻力的2-4倍。
轴流风机的特性，风阻变大的时候，风扇和电机功耗会自动趋向重载状态，甚至会过载、发热和烧毁，也就是说轴流风机无法保证空气净化器的质量。
离心风机的特性，风阻变大的时候，风扇和电机功耗会自动趋向轻载状态，虽然风量会减小，但是能保证空气净化器的质量和使用安全。
3、设计要求
风机不仅决定净化能力，还决定设计难度。
不同风机有不同的设计要求，轴流、离心和混流相比，选用离心风机对产品的设计能力、制造成本都有高的要求。
1）、离心风机都需要配合完整的内外风道设计，而且需要自行设计。
离心风机旋转过程中空气平行于电机轴向进入叶片空间，随叶轮旋转改变成径向，沿半径方向从叶轮中甩出，改变了流向，同时在经过旋转的叶轮时获得加速，取得了动能。
由于空气流向改变，在电机和风叶之外、还需要一个完整的导流蜗壳用于导流和扩压的作用。
适合用于空气净化器规格的离心风机较少，很难直接采购到现成的适合空气净化器的风机，而且普通的离心风机也不一定能达到穿透率网的要求。
所以大部分需要厂家自行进行设计和订作，需要投入相当大的精力和成本。
离心风机对设计能力有较高的要求，那么轴流风机和混流风机就简单很多了，而且还可以直接采购无需设计。
2）、轴流风机的设计简单，轴流风机式的空气净化器也无需做风道设计，那么相应的降低了设计要求。
轴流风机的制造成本低，并且有现成的“货架成品”，通过采购的方式就可以获得，无需研制。
3）、混流风机使用时不会改变风的流向，风机本身对风道的设计要求比较低，部分品牌为了设计的方便或有部分滤网配置较低的品牌选择使用混流风机。
因此，通过风机类型可以判断出空气净化器品牌所在企业的研发能力，某些品牌选择轴流风机并不是从产品性能角度考虑，而是从产品的可获得性和成本角度考虑或者该类企业根本没有研发团队。
为什么瑞典某著名B品牌销售了这么多年的空气净化器仍然使用轴流风机？想必和对方的研发能力有关，可能研发团队的能力较弱被迫选择轴流风机，也可能根本没有研发团队，而是做了一个高级组装工作。
三、fresh air风机
fresh air空气净化器是在研发部总工程师的严格管理和控制之下诞生的，将国际标准化组织（ISO）的标准制定为fresh air空气净化器、新风净化机、新风净化一体机的合格标准化，所有零部件均由研发团队自行设计，包括风机、滤网等核心部件及最小零件螺丝都是自行设计。
所有零部件均自行设计最大的优势是可控，即零部件的性能、质量均能达到设计要求，并且可以避免风险；最大劣势是增加研发费用、延长研发时间，因为所有的零部件都需要制作模具。
对于美国企业的研发团队来说是否科学、是否符合规律是产品研发的本质和前提，在专业研发团队的眼中选择轴流风机是不科学的，尽管风量大。
因此，fresh air研发团队从科学、合理、高效角度考虑，选择离心风机。
fresh air空气净化器的研发团队严格遵循美国文化下的设计思路，设计之初首要思考的问题是安全问题，即如何避免事故发生或如果出现事故如何避免伤害和损失。
如同在汽车出现事故的情况下，欧美车的设计思路是刹车优先，而非油门优先。
那么，在选用风机的时候首要考虑的问题是电机隐患即电机过热问题。
fresh air研发团队对电机部分是如何控制的呢？
1、选择安全系数高的离心电机
2、在选择电机生产商的时候制定了两个不可更改的要求：
1）、生产商必须有3C认证
2）、电机在空载状态下不能过热
3、在筛选电机生产商的过程中制定了严格的筛选流程：
1）、淘汰没有3C认证的生产商，初步确定名单。
2）、从初步确定的生产商处采用样品
3）、对样品的进行测试，包括空载试验、负载试验、温升试验、效率试验等
4）、根据测试结果确定生产商
4、自行设计电机，并制作模具
电机只是风机的一部分，fresh air对风机还有那些设计呢？
首先是风机的叶轮，对于同样转速的电机，不同的叶轮也会带来不同的效果，为提升风机的性能，fresh air采用的叶轮为工程师反复论证实验设计，完全定做的叶轮，其中叶轮叶片的弯曲度也会影响出风的速度，对每一片叶片的角度，工程师也采用了多次模拟实验才做了决定。
其次，好的电机和叶轮还需要科学的风道设计，尤其是离心风机，搭配以导流涡壳才能最大限度的发挥其风压的优势。
fresh air工程师在机器整体设计时就考虑了这一点，给导流涡壳设计留下了足够的空间，最终制作出来的导流风道，可以完美地达到降阻扩压的效果。
