FAIL-SAFE
Type
DESCRIPTION
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.

Application
D ... Lamps
(By Others)
H ... Ballast
Standard Class P, CBM/ETL ballast.
Applications include surgical
suites, clean rooms, technical and
biomedical labs, food processing/
testing centers and pharmaceutical
labs.
E ... Lens Retention
I ... Gasket
Unique, Particulock(TM) lens
retention system utilizes
continuous, 18 ga. media
clampdowns to sandwich
gasketing and integrate lens and
door frame for even environmental
seal.
White, closed cell, Flexiseal(TM)
gasketing surrounds perimeter of
lens to seal lens to door frame and
around perimeter of door to seal
door to housing. Another layer on
the flange seals fixture to ceiling
system after installation.
A ... Lens
(To be specified.) One-piece, clear
extruded lens with internal prism
pattern. Choice of prismatic acrylic,
prismatic polycarbonate, Radialens
(TM) or prismatic tempered glass
on environmental side. See Lens
Options.
F ... Hinge
J ... Access
MAF
Two braided, stainless steel cables
on one side of door provide
hinging.
A gasketed access plate on top of
the housing with two flattened,
7/8" diameter knockouts allows
connection of vapor tight conduit
fitting.
B ... Fasteners
17W - 40W
Fluorescent
Flush mounted, stainless steel
machine screws secure through
captive cage nuts in housing and
are evenly spaced to compress
gasketing on all sides.
G ... Door
(To be specified.) One-piece, 18
ga., fully gasketed, outside flanged
door with die-formed edges
eliminates seams which could
entrap microscopic contaminants.
