to 100 percent supply air. The fan operates in conjunction with the supply fan. The relief damper modulates in response to economizer damper position on Constant Volume air handlers.

•100 Percent Modulating Return Fan with Statitrac Control and Variable Frequency Drive and Bypass—Provided with all the necessary controls to control/ maintain building space pressure through a VAV air handler. The Variable Frequency Drive (VFD) modulates the speed of the return fan motor in response to return plenum pressure. A differential pressure control system, Statitrac, uses a differential pressure transducer to compare indoor building pressure to atmospheric pressure. The Statitrac control system modulates the relief dampers to control the building pressure to within the adjustable, specified deadband that is set at the Human Interface Panel.

•100 Percent Modulating Return Fan with Statitrac Control and Variable Frequency drive and Bypass—Bypass control provides full nominal airflow in the event of drive failure.

Filters

•No filters (two-inch nominal thickness throwaway filter rack only) option—Includes a galvanized steel filter rack (less filter media) with filter channels to handle a complete set of two- inch nominal thickness throwaway filters to accommodate applications which require field supplied filters.

•No filters (bag/cartridge filter rack with throwaway prefilter rack only) option—Includes a galvanized steel filter rack (less filter media) to handle a complete set of two-inch or four- inch (depending on airflow) nominal thickness throwaway prefilters and 7/8” nominal header thickness bag or cartridge filters to accommodate applications which require field supplied filters.

•Standard throwaway filters—U.L. Class 2, two-inch nominal thickness, high efficiency pleated media filters rated MERV 7 per ASHRAE 52.2. Filters are mounted in a galvanized steel filter rack.

•MERV 15, 90-95 percent bag filter option—Nineteen-inch deep bag filters are U.L. Class 2 and have synthetic media mounted to a 7/8” nominal thickness header frame. These bag filters have an efficiency rating of MERV 15 per ASHRAE 52.2. To ensure maximum bag filter life, two-inch prefilters are included with the bag filters. Filters are mounted in a galvanized steel filter rack.
