Cooling Tower Intake Filter – What Not To Do

Marley Cooling Tower with roll filter media over the face of the intake opening. Important Note: Roll filter media is not designed for use on cooling towers. It will cause an excessive increase in static pressure even before dirt and debris loads the filter. Furthermore, when roll media becomes saturated with moisture, it further impedes airflow and impacts cooling efficiency. Pulley-Mount Air Intake Filters were installed on these units.
