The Abtech Flow-Thru Troffer allows HEPA filtered air to flow through the fixture and into the Cleanroom. It is ideal for Class 10 to 100,000 Cleanroom environments, including electronic laboratories, biomedical laboratories, pharmaceutical laboratories, hospitals, and R & D testing centers. Housing fits into either 1", 1-1/2" or 2" standard

T-Grid systems, and accepts standard 2' x 4' HEPA air filter.
The troffer contains no holes which would allow air passage from a plenum through the fixture, while closed cell gaskets and silicone seal the T-Grid system to prevent unfiltered air from entering the cleanroom. The housing is fabricated from 20 gauge steel with spot welded, sealed ends and is finished with a white powdercoating.

Standard ballasts are 120V, T8/32W electronic for use with (4) medium bi-pin lamps. The ballast is mounted inside the housing and is removable from roomside. All electrical components are U.L. listed. Other voltages and lamp specifications are available.

A white box cell louver (1/2" x 1/2" x 1/2") is inserted in an anodized extruded aluminum frame which is hinged to open, permitting removal of the lamps and ballast from roomside.

All fixtures have been tested and reported in compliance with Federal Standard 209D.
