Knife-edge HEPA filters
HEPA panels with an integral knife-edge frame that pushes into a gel-filled sealing channel, for terminal positions where a gasket seal cannot guarantee tightness.

Description
Knife-edge HEPA filters are HEPA panels whose aluminium profile frame carries a perimeter knife edge (side curtain). The knife edge pushes into a gel-filled sealing channel of the matching housing, so the gel wraps around the blade and forms a continuous seal that gasket frames cannot achieve on uneven flanges. The source catalogue lists H13 at 99.97–99.99 % and H14 at 99.995–99.999 %, both at 0.3 µm. Multi-module constructions combine small filter units for even velocity across the face.
Features
- Integral knife edge on the aluminium frame for gel-channel sealing.
- H13 and H14 efficiency classes at 0.3 µm, per the source catalogue.
- Continuous gel seal tolerant of uneven mounting flanges.
- Modular multi-unit constructions for even face velocity at large sizes.
Applications
- Terminal filtration in biopharmaceutical cleanrooms
- Electronics and semiconductor fabrication areas
- Hospital pharmacy and sterile preparation areas
- Food processing plants with high cleanliness requirements
