The Fail-Safe MAF Series is designed for use in horizontal or non-laminar air 
flow clean rooms. The enclosed and gasketed housing and one-piece, out-
side flanged door protect against infiltration of airborne bacteria. The die 
formed edges on the door frame and the hole-free design of the housing 
prevent air exchange between the fixture and plenum, allowing relamping 
without contamination of the clean areas. These luminaires are U.L. listed 
and C.S.A. certified for wet locations and manufactured in accordance with 
U.S.D.A., F.D.A., N.S.F. and Federal Standard 209E guidelines. Rated for 
high pressure hose down at 200 PSI.

suites, clean rooms, technical and 
biomedical labs, food processing/
testing centers and pharmaceutical 
labs.

continuous, 18 ga. media 
clampdowns to sandwich 
gasketing and integrate lens and 
door frame for even environmental 
seal.

F ... Hinge
Two braided, stainless steel cables 
on one side of door provide 
hinging.
