An air washer system purifies the air and cleans it by adding water to trap the impurities and pollutants. It includes a fan that extracts air through various damp plates or pads. Here, the water present in the plates or pads absorbs all the dirt, dust and other harmful particles from the air. The Air washer unit then releases the clean air back inside the room, with the high humidity that was present before.
Most people use air washers in areas or countries with higher dust levels and air pollution, like construction sites and industrial facilities. You can also use them in offices or homes to enhance the air quality and improve the humidity levels. An Air washer system is highly beneficial for those who are suffering from dry skin or respiratory problems. It has an HVAC device that combines air purification and dehumidification functions to moisturize and cleanse the air.
For what purpose an Air washer system used?
You can find the application of an Air washer unit for various purposes, including the following.
Commercial Infrastructure
Air washers in commercial infrastructure maintain clean and fresh air for the occupants.
Healthcare facilities
Healthcare facilities use air washers to create a sterile environment, controlling the contaminants, and maintaining optimal humidity for patient comfort and medical equipment.
Data centers
It maintains accurate humidity control and healthcare settings for long-term equipment lifespan and smoother performance.
Industrial centers
In industrial centers, the Air washer system eliminates all the pollutants, maintains appropriate humidity levels and controls the dust.
Educational institutions
Different educational institutions like universities, colleges and schools use an Air washer unit to improve the air quality in the libraries, classrooms, and other segments to creative a clean and conducive learning environment.
What are the different varieties of the Air washer system?
There are primarily three types of air washers available in the market.
Indirect
In this type of air washer, air passes through a sensible heat exchanger. It then cools the air and passes it through wet pads to get rid of all the pollutants. The machine then heats the clean air and releases it back into the room. This unit is highly efficient in eliminating all the impurities and needs less water. But the maintenance costs of these machines are high.
Direct
Direct or single-pass air washers implement a one-pass system. Here, the unit washes the air once and releases it back into the room. The air passes through a number of wet pads where water thoroughly cleans it. The humidified, cool and clean air is then released back into the space. They are less expensive than to indirect ones, but need more water to clean.
Multi pad
Multi-pad air washers are compact in size and thus leave fewer footprints. Since there are more areas for multiple pads, it results in improved cooling. The maintenance of this Air washer system is hassle-free, as you can remove the pads and clean them. They are also highly energy efficient.
FAQ
What is the working principle of an air washer?
Air washers use a rotating disk or drum containing a wet filter material. When the dry air enters the filter, the water present inside it evaporates, thus humidifying and cooling the air. The impurities present in the air also get trapped inside the filter. The moist air then goes outside and is distributed throughout the room. It offers instant relief to people having allergies, other respiratory difficulties, and dry skin and increases the humidity level. For efficient performance and prevention of the mold, bacteria and other dangerous contaminants formation, it is mandatory to regularly replace and clean the filter in the air washer system.
End Words
Air washer system includes accurate humidification control, self-cleaning and remote control functions, and energy efficiency to improve the air quality. There are various types of Air washer unit available in the market, like direct and indirect evaporative. Air washers can adapt themselves to the altering weather conditions, ensuring optimal humidity control, user convenience, and seamless integration.
