DESCRIPTION
The Fail-Safe SCH24 Series is designed for use in horizontal or non-laminar
air flow clean rooms. The enclosed and gasketed housing and door protect
against infiltration of airborne bacteria. Fixtures tested to 100 PSI hosedown.
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 relamping without contamination
of the clean areas. These luminaires are manufactured in accordance with
U.S.D.A., F.D.A., N.S.F. and Federal Standard 209E.
Application
The SCH24 Series is suitable for
use in I.E.S. Class 10 (M2.5), 100 (M
3.5), 1,000 (M 4.5), 10,000 (M 5.5)
and 100,000 (M 6.5) clean room
environments. Applications include
cleanrooms, technical and bio-
medical labs, food processing/
testing centers and pharmaceutical
labs.
A ... Lens
Lens is clear extruded with prisms
positioned inside fixture and
smooth surface on the outside for
easy cleaning.
B ... Fasteners
Flush mounted, stainless steel
machine screws secure through
captive cage nuts in housing and

environment.
F ... Hinge
Reversible drop-link hinging
system for easy maintenance.
G ... Door
Optional) Door can be extruded
aluminum, fully gasketed, outside
