A fixed seal rubs while the door moves.
Deflation retracts the active profile before opening.
STJH-AIRTIGHT-CLEANROOM-DOOR-GASKET-INFLATABLE
Airtight Cleanroom Door Gasket Inflatable Silicone
Inflate the silicone perimeter only after closure, then retract it before the door moves.
- Retraction reduces contact during door movement.
- Joined-loop construction suits a continuous perimeter.
- An air connection distinguishes the active seal from passive profiles.
Product Introduction
This gasket forms an active sealing loop from a hollow silicone extrusion with an air connection. Pressure expands the profile against the mating surface, and deflation allows it to retract for opening. Straight lengths, endless loops and molded-corner arrangements accommodate different door geometries. The supplied component is the seal assembly, intended to work with a separate pneumatic supply and control sequence rather than relying on the leaf to compress a fixed bulb.
Key Features
- Retraction reduces contact during door movement.
- Joined-loop construction suits a continuous perimeter.
- An air connection distinguishes the active seal from passive profiles.
Technical Parameters
