The AES Environmental Filtoroll units is a roll filter media designed for use in limited operating period or low occupancy establishments.

 Principle of Operation 

 In the AES Environmental Filtoroll unit the media drive motor is a 62 watt integral gear motor directly coupled by chain and/or gear drives to the dirty media spool. 

The in-built pressure differential switch ensures a constant resistance and therefore a constant airflow despite particulate build-up. The edges of the media are securely located in edge-sealing channels of generous depth to prevent any leakage of air around the edges of the media. 

Performance  

The normal operating resistance of a Filtoroll unit is 100 Pa at rated capacity. Units are available in size from 2473 L/s up to 73,000 L/s capacity. ASHRAE tests give an efficiency of 83% at rated air flow. 

Selection 

In laying out a filter system it is recommended that there is 1 metre space on the air-on side of the filter for maintenance purposes. Contact your local AES Environmental office for an engineered solution.
