Especially designed for drop ceilings, the F57A is ideal for large spaces. Use it in banquet rooms, lounges, conference areas and training rooms-anywhere there is a large volume of air to filter, and a drop ceiling with at least 13 1/2 inches clearance above.

With the F57A installed unobtrusively in the ceiling, you'll hardly know it's there-except for its effects on the indoor air quality. Its attractive, off-white grille matches typical overhead commercial fixtures. And the hinged door swings down for easy access to both the pre-filter and electronic cells.

Compact and efficient, this electronic air cleaner captures over 94% of particles from the air passing through the filter (0.5 microns and larger). It then re-circulates cleaner air throughout the room using a Coanda airflow pattern.

The F57A operates at your choice of speeds-HIGH, MEDIUM, or LOW-using push-buttons on the front panel of the unit. Other convenient control options include a remote wall switch, and a wireless remote control.

Reliability is built right in. A solid state power supply for consistent voltage output, built-in performance indicator, high/low performance switch, commercial-duty air cleaner cells and a maintenance free motor with sealed bearings all work together to ensure maximum reliability.
