Perkenalan produk

The gel seal is a U-shaped channel integrated into the downstream face of a HEPA or ULPA frame. A non-flowing silicone compound fills the channel and surrounds the terminal or holding-frame knife edge when the filter is clamped into place. Unlike a flat foam gasket, the gel conforms around small surface irregularities with limited compression travel. The channel is closed at the corners to keep gel depth continuous across the full perimeter.

Fitur utama:

Soft silicone flows locally around the knife edge to close small surface variations.

A rigid aluminum channel controls gel depth and prevents edge spread.

The seal can accept repeated knife-edge insertion when the gel surface remains clean and intact.

Corner joints are sealed to maintain one continuous perimeter reservoir.

Kekhawatiran produk pelanggan

A terminal filter needs a low-bypass seal within limited clamp travel and around small knife-edge irregularities.

A flat gasket does not conform to a slightly uneven knife edge.Soft gel displaces around the edge and maintains contact along both sides.

Excess gel escapes when the filter is inverted for installation.A thixotropic non-flowing formulation remains inside the enclosed channel.

An open corner creates a direct bypass route.Mitered and sealed channel corners preserve the continuous gel reservoir.

Deep knife-edge insertion bottoms against the aluminum channel.Specified gel depth and clamp stop keep the metal edge within the soft sealing zone.
