FAQs About Air Handling Units
United Rentals carries air handling units for sale, perfect for any industrial workspace. Air handling units, or AHUs, offer air ventilation and purification throughout large spaces, including multiple rooms. Air handler units work by collecting air from outside, which is then treated, heated or cooled and cleaned, then distributed throughout the desired space. These units allow for temperature control in your space, assuring workplace comfort and stability. A critical part of your HVAC system, air handling units are often seen in medium-sized to industrial buildings and can be customizable to fit your space requirements.

Keeping your air handling unit clean is essential for optimal performance and indoor air quality. Here are some expert tips on how to clean your air handling unit. Gently wash away any accumulated dirt outside the unit using a mild detergent. Clean the coil at the beginning of every cooling season using a coil cleaner or a mixture of water and mild detergent. Wipe down the unit's exterior — avoid using harsh chemicals as they can damage the unit. Check and clean the filters regularly to ensure proper airflow and filtration. Inspect and clean all drainage leading from the unit. Ensure the drain tubes are clear and free of debris to prevent clogs and potential water damage. Lubricate and grease the motor and blower bearing per the manufacturer's recommendations. Regular maintenance of your air handling unit prolongs its lifespan and contributes to a healthier and more efficient HVAC system.
Calculating the CFM (cubic feet per minute) of an air handling unit is crucial for determining the airflow capacity of the system. Several methods can be used to calculate CFM depending on the requirements and factors involved. Here are a few approaches:
- System Capacity: The CFM can be calculated based on the system's capacity or the desired ventilation rate for a particular space. One way to determine this is by dividing the total volume by 60. For example, if you have a standard room with a volume of 4,800 cubic feet and you aim for two air changes per hour (ACH), the calculation would be 4,800/60 = 80 CFM.
- Velocity x Area: Another method involves calculating CFM by multiplying the velocity of air (in feet per minute) by the area through which the air is passing. This formula can be used when you know the required velocity and the area size.
It is important to note that these calculations provide general guidelines, and consulting with HVAC professionals or referring to specific industry standards may be necessary to ensure accurate CFM calculations for your air handling unit.
