Perkenalan produk

The compression gasket is bonded to the upstream or downstream face of a HEPA frame and seals against a flat housing flange. Closed-cell polyurethane, neoprene, EPDM or silicone limits air transmission through the foam itself, while the selected hardness lets the gasket recover after clamping. Mitered, vulcanized or moulded endless corners remove gaps at the perimeter. Adhesive backing holds the profile in position during filter installation.

Fitur utama:

Closed-cell structure resists through-gasket airflow.

Defined thickness and hardness provide a predictable compression window.

Endless or sealed mitered corners eliminate open butt joints.

Pressure-sensitive adhesive keeps the profile aligned on the filter frame.

Kekhawatiran produk pelanggan

Perimeter leakage can remain even with an efficient filter if the gasket is porous, misaligned or unevenly compressed.

Open-cell foam allows air to pass through the gasket body.Closed-cell polyurethane, neoprene or silicone forms a substantially less permeable seal.

A butt joint opens at the frame corner.Moulded endless or sealed mitered construction closes the entire perimeter.

Over-tightening permanently flattens the gasket.Specified hardness and clamp travel keep compression within the elastic recovery range.

The strip moves out of position while the filter is inserted.A continuous adhesive backing fixes the gasket to the cleaned frame surface.
