Air Filter Unit

Our most popular fan-filter unit is the Design-Aire SL. The new "slim line" housing was specifically engineered to accommodate tight ceiling spaces, a condition that rendered our older model and numerous competing models unsuitable for installation. The Design-Aire fan-filter units in our entire series are equipped with numerous advantageous features as standard.KEY FEATURES

Simple To Install
These units are more easily slid into ceilings due to their lightweight housing and 11.5" height. They can be connected to standard 115V outlets using the 3-prong electrical cord.
HEPA Duration
The variable speed control enhances the lifespan of the HEPA filter by enabling the motor to operate at a higher speed as the filter's load increases. This maintains a consistent airflow and reduces the frequency of filter replacements.
Energy Costs
A maximum of 2.16 amps is utilized by each unit.
Ease of Access
The filter housing contains a 115V duplex electrical outlet that enables the connection and operation of up to five units from a single 15 amp circuit.STANDARD FEATURES
