Airtight غرف نظيفة الباب طوقا
A smooth resilient perimeter seal that compresses between the cleanroom door leaf and frame to limit uncontrolled air leakage.
- Continuous Perimeter Seal
- Low Compression Set
- Replaceable Profile
- Smooth Cleanable Surface
مقدمة المنتج
The airtight cleanroom door gasket is extruded from silicone or EPDM into a hollow bulb, blade or multi-lip profile sized to the door-frame groove. Controlled compression closes small installation tolerances around the jamb and head while allowing the leaf to operate without excessive force. A clip-in, channel-retained or bonded base keeps the exposed seal continuous and permits replacement when the compression profile eventually wears.
الخصائص الرئيسية
Smooth non-porous surfaces support regular wipe-down without exposed fibres.
Moulded or bonded corner joints preserve continuity around rectangular door openings.
Replaceable channel-retained profiles reduce downtime when the sealing lip is damaged.
مخاوف المنتج للعملاء
Perimeter leakage often occurs at corners and variable frame gaps rather than across the center of the door leaf.
A hard seal increases closing force and prevents the latch from seating consistently.The hollow gasket profile compresses at a controlled load across the designed gap.
Cut corners separate over time and create direct leakage paths.Continuous extrusions are joined with moulded or vulcanized corner connections.
A permanently bonded gasket is difficult to replace after mechanical damage.Clip-in and channel-retained bases allow the worn profile to be removed independently.
