Gasket-Seal فلتر HEPA
A rigid HEPA panel fitted with a closed-cell perimeter gasket that seals against a flat housing flange under controlled compression.
- Closed-Cell Compression Gasket
- Flat-Flange Compatibility
- Simple Visual Inspection
- Replaceable Seal Option
مقدمة المنتج
The gasket-seal HEPA filter uses a flat closed-cell neoprene, EPDM or polyurethane gasket bonded to the upstream or downstream flange of an anodized-aluminum, galvanized or wood cell. Retaining clips or a clamping mechanism compress the gasket uniformly against the housing's flat sealing face. The mini-pleat or separator-style HEPA pack is potted independently into the cell, while dovetailed or continuously poured gasket corners prevent leakage at the perimeter joints. This familiar dry-seal arrangement suits built-up banks and terminal frames with accessible, flat mating surfaces.
الخصائص الرئيسية
A broad flat gasket face is easy to inspect for dirt, tears and incomplete contact before installation.
Dovetailed or seamless corners maintain continuity around the complete perimeter.
Upstream and downstream gasket positions accommodate different filter-bank loading directions.
مخاوف المنتج للعملاء
Dry gasket seals depend on clean mating surfaces and uniform compression around every side of the filter frame.
Uneven clamp force leaves one corner of the filter unsealed.A resilient full-width gasket and distributed retaining points maintain perimeter compression.
Open-cell foam allows leakage through the gasket body.Closed-cell neoprene, EPDM or polyurethane provides a low-permeability compression barrier.
Butt-jointed gasket corners separate during filter handling.Dovetailed interlocking corners or a continuously poured gasket remove straight-through corner gaps.
Repeated replacement leaves adhesive residue and a distorted seal face.A replaceable preformed gasket and clean flat flange simplify inspection and renewal.
