An industrial air washer offers an efficient and economical solution for delivering cool air during summer and warm air during winter in both industrial and commercial environments. Beyond temperature control, it also helps purify and humidify the air. In the following section, we’ll explore its features and uses in more detail.
What is an Industrial Air Washer?
An industrial air washer works similarly to a residential air washer by cooling or heating the incoming air for a building or warehouse. It also purifies the air by removing pollutants and allergens using effective filtration, all with minimal energy use and cost.
Here is a brief overview of how the air washer system works:
1. Intake of fresh outdoor air through the inlet fan during summer (when relative humidity is below 40% RH)
2. High-pressure water spraying through nozzles onto the passing air to absorb heat and reduce temperature (in evaporative cooling mode)
3. Passing the air mixture through multiple filters at the beginning and end of the air washer and directing it to ducts and air outlets
4. Hot water from a boiler or heating package flows into the hot water coil in winter, heating the coil surface and thus warming the passing air through direct contact (in heating mode)
5. Recirculating indoor air during winter and mixing it with fresh air using the same fan (in heating mode)

Industrial Air Washer Features
The main Features and advantages of industrial air washers include:
-
More affordable than refrigerant-based systems like chillers
-
Lower energy consumption
-
Longer equipment lifespan
-
Simple and low-cost maintenance
One of the key considerations when using industrial air washers is that these systems provide cool air during summer by utilizing fresh outdoor air and water. They should only be used under the following conditions: first, the relative humidity of the outdoor air in summer must be less than 40%, and second, sufficient clean water must be available. In such conditions, by carefully calculating and installing the air ducts with proper dimensions (according to Ductulator standards), respecting the internal bending radius, maintaining proper duct angles, and ensuring adequate static pressure from the centrifugal blower fan, you can effectively benefit from the cool air in summer.
Additionally, by installing return air ducts for winter use, the device can efficiently warm up the indoor air with minimal energy consumption.
Applications of Industrial Air Washers
Industrial air washers are widely used in the following settings:
-
Industrial warehouses and factories
-
Commercial and office spaces
-
Educational buildings, schools, and universities
-
Exhibition centers and large retail stores
-
Airport terminals and transportation hubs
-
Sports halls and gyms
-
Manufacturing plants
-
Large and small residential complexes
-
Correctional facilities, and more
When selecting and purchasing an air washer for your project, you need to determine in advance the required airflow capacity in summer (CFM), the heating load (BTU/hr), the coil's heating surface area, the required static pressure of the blower fan, and the necessary air filters.

Residential vs. Industrial Air Washers
As mentioned, both industrial and residential air washers operate on similar principles, but in industrial and commercial spaces, the air volume is much larger due to the size of the halls or the high ceilings of industrial warehouses. To save energy in winter, a greater volume of return air is recirculated and mixed with fresh air. Since the return air is already warmer, it reduces the need for heating. Additionally, during cooling mode, these units can also capture airborne dust and particles through water spraying. Therefore, air washers are widely used for controlling microorganisms, allergens, pathogens, and VOCs in large spaces such as gyms, factories, exhibitions, warehouses, and more.
