The Design-Aire SL is our most popular fan-filter unit. The new “slim line” housing was designed to fit into tight ceiling spaces, where our older model and many competing models could not be installed. Our entire series of Design-Aire fan-filter units come standard with many beneficial features. KEY FEATURES Easy Installation The 11.5” height and light-weight housing of these units make them easier to slide into ceilings. The 3-prong electrical cord allows them to be plugged into standard 115V outlets. HEPA Duration The variable speed control helps increase HEPA filter life, by allowing the motor speed to be increased as the loading on the filter increases. This keeps the airflow consistent and results in fewer filter changes. Energy Costs Each unit only uses a maximum of 2.16 amps. Convenient Connections A 115V duplex electrical outlet located in the filter housing allows up to 5 units to be connected and run from one 15 amp circuit.
