BLASI – Centre sealing rubber
The BLASI centre sealing rubber is a precision-engineered elastomer component designed for BLASI automatic revolving door systems. Positioned at the central axis where door wings meet during rotation, this sealing rubber maintains continuous contact between adjacent wing edges, preventing air leakage, dust ingress, and noise transmission. The flexible rubber compound ensures smooth wing passage while creating an airtight barrier that preserves climate control and acoustic comfort. Engineered for thousands of compression cycles, this direct replacement restores complete perimeter sealing and optimal performance to commercial revolving door installations.
Product Details
The BLASI centre sealing rubber serves as the critical sealing interface in automatic revolving door systems where rotating wings continuously pass each other at the central rotation axis. This specialised elastomer maintains permanent contact between wing edges throughout the complete 360-degree rotation cycle, creating an airtight barrier that eliminates draughts, blocks dust penetration, and prevents sound transmission between interior and exterior environments.
Manufactured from premium rubber compound with excellent compression set resistance, the centre sealing rubber withstands constant flexing and pressure without permanent deformation. Its precise durometer ensures sufficient sealing force while allowing smooth wing passage without drag or resistance. Worn centre seals cause significant air leakage, energy loss, and operational noise. Replacing with genuine BLASI centre sealing rubber restores complete environmental separation, thermal performance, and quiet operation essential for premium commercial entrances while maintaining the smooth, reliable rotation characteristic of BLASI revolving door technology.
