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.

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.
