Cleanroom Lighting and Electrical Equipment
Airtight Cleanroom Light
A compression-sealed LED fixture designed to preserve the pressure boundary at the lens, housing seams, cable entry and ceiling interface.
- Compression-Sealed Lens
- Welded Enclosure Seams
- Airtight Ceiling Interface
- Sealed Electrical Entry
Product Introduction
Unlike a general cleanroom fixture, the hermetically sealed luminaire treats every enclosure path as part of the room pressure boundary. The metal back box uses continuously closed seams, the lens is compressed against a continuous gasket, and the ceiling trim seals independently to the panel opening. Cable entry passes through a rated gland or sealed conduit hub so wiring does not bypass the enclosure seal.
Key Features
Closed housing seams prevent leakage through folded corner joints.
The ceiling flange has a dedicated seal separate from the removable optical door.
A threaded cable gland closes around the incoming power cable.
Captive compression latches apply repeatable pressure after maintenance.
Customer Product Concerns
Pressure-controlled rooms lose integrity when fixture seams and cable routes form parallel leakage paths around the ceiling seal.
A sealed lens still leaks through an open back-box corner.Continuously closed enclosure seams complete the barrier behind the optic.
Removing the lens disturbs the ceiling-to-fixture seal.Independent ceiling and optical gaskets separate those two interfaces.
Loose latches compress one side of the gasket more than another.Evenly spaced captive compression points load the perimeter consistently.
An ordinary cable knockout bypasses the sealed housing.A matched threaded gland seals directly around the supply cable or conduit.
Typical Applications
Positive-pressure aseptic roomsNegative-pressure containment areasSterile filling suitesHigh-integrity airlocks
