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, outside 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 are
manufactured in accordance
with U.S.D.A., F.D.A., N.S.F.
and Federal Standard 209E.
The MAF Series is suitable for
use in I.E.S. Class 100, 1,000,
10,000 and 100,000 clean room
environments.

1The KSH25 provides improved visual performance and wide angle distribution. This lens has an integral prism pattern designed so that
prisms face the lamp cavity and still supply superior photometrics. Highly recommended for all high tech manufacturing environments.
2For specific electronic ballast, specify brand and catalog number. 3Products available in non-US voltages and 50 Hz for international
markets. Consult your Cooper Lighting Representative for availability and ordering information. 4Electronic ballast not available with 20W
