BLASI – Rubber seal Vitrax PR

The BLASI – Rubber seal Vitrax PR provides ultimate environmental protection for drum-to-ceiling transitions, wing perimeter clamping zones, and side panel interfaces in FlipFlow revolving door systems, achieving Class 6 airtightness through 35% compression capability while accommodating ±2mm thermal movement across two-wing security, three-wing standard, and four-wing high-capacity BLASI configurations serving global luxury hospitality facilities. Proprietary Vitrax PR formulation combines 92 Shore A rigid mounting backbone with 45 Shore A hollow sealing chambers delivering zero compression set after 200,000 cycles while maintaining elasticity from -40°C freezer storage areas to +90°C rooftop exposures.

The BLASI Rubber seal Vitrax PR co-extruded design integrates metal detectable carrier wires preventing total ingestion during clamp assembly while precision-ground sealing lips achieve zero-gap closure against stainless cladding. Chemically cross-linked structure resists jet wash detergents, ozone attack from HVAC systems, and hydrocarbon degradation from gearbox lubricants common in entrance maintenance.

Factory-packaged 100m master reels with laser-etched sequential meter markings eliminate field measuring errors while V-groove installation guides ensure perfect alignment in tight drum clearances. Field technicians specify BLASI Rubber seal Vitrax PR for premium installations requiring >30-year service life, exact 15.2mm cross-section matching factory clamp channels, and universal compatibility across all BLASI drum diameters worldwide. This perimeter sealing system maintains complete environmental integrity ensuring optimal energy performance and pedestrian comfort throughout building lifecycle.
