Product Introduction

The integral channel measures 0.500 x 0.543 in, or approximately 12.7 x 13.8 mm, and is formed in an anodized aluminum HEPA frame. Elastic polyurethane gel fills the trough and receives the housing knife edge to create a continuous fluid perimeter seal. The relatively deep channel is suited to V-bank and other high-capacity filters where positive knife-edge engagement must be maintained through normal installation tolerances.

Key Features

Defined knife-edge immersion

The deep trough provides a controlled volume for the housing edge to enter without reaching the channel bottom.

Self-conforming fluid seal

Elastic gel closes around the inserted edge and accommodates minor surface variation.

Integral aluminum profile

The channel is part of the anodized frame rather than a separately attached gasket carrier.

Solutions for Your Application

The housing knife edge bottoms in the trough and displaces too much gel.Verify knife-edge height and channel fill depth so engagement remains within the intended 13.8 mm trough.

Dirt or cured residue prevents the gel from closing around the edge.Inspect and clean the knife edge and reject channels with contaminated, torn or chemically degraded gel.

Available Options

Confirm channel profile, PU gel grade, fill level, frame dimensions, knife-edge geometry, temperature and process-chemical exposure.
