FAIL-SAFE
DESCRIPTION
DIMENSIONS
The Fail-Safe SCF Series is
designed for use in horizontal
or non-laminar air flow clean
rooms and features the added
convenience of field retrofitting
for flange or grid
installations.The enclosed and
gasketed housing and outside
flanged door protect against
infiltration of airborne bacteria.
Fixture tested to 100 PSI hose
down. Higher ratings available
(consult factory). The mitered
edges on the door frame and
the hole-free design of the
housing prevent air exchange
between the fixture and
plenum, allowing re-lamping
without contamination of the
clean areas. UL Listed Wet
Location. These luminaires are
manufactured in accordance
with U.S.D.A., F.D.A., N.S.F. and
Federal Standard 209E. The
SCFSeries is suitable for use in
