Produkteinführung

This cellular polyurethane gasket is poured directly onto the filter frame as one continuous perimeter. Removing cut-and-joined corners eliminates common splice gaps and gives the housing clamps a consistent foam section to compress. The gasket can be located upstream, downstream or on both faces for standard cleanroom service, provided the housing travel is matched to its thickness and recovery characteristics.

Key Features

No corner splices

Continuous molding removes four butt joints that can open under uneven clamp pressure.

Uniform compression section

A controlled foam bead supports consistent sealing around the complete filter frame.

Flexible face location

The gasket can be applied to either airflow face or both when the installation interface requires it.

Applications

For pharmaceutical, healthcare and clean-process HEPA filters using conventional gasket-seal housings and terminal frames.

Solutions for Your Application

A cut gasket opens at the corner and creates a difficult-to-find bypass path.Use the seamless poured perimeter and inspect the complete bead before loading the filter.

Excess clamp travel permanently crushes the cellular foam.Set retainers for the specified gasket compression and do not substitute a different bead thickness without adjustment.

Verfügbare Optionen

Specify bead width and height, face location, foam firmness, frame material, adhesive preparation and housing compression travel.
