Aluminium Foil Separator HEPA Air Filter

Ultra-fine Glass Fiber Paper Composition: Made from glass fibers of varying diameters (typically from fractions of a micron to several microns) via wet-laid or dry-laid processes.

Separator: The separator supports and secures the pleated filter media, ensuring uniform airflow channels and preventing media collapse under high differential pressure.

Primary Material: Aluminum Foil

Frame: The frame provides structural integrity for the entire filter and facilitates installation.Primary Materials: Plywood Aluminum Profile Stainless Steel Galvanized Steel

Sealant: The sealant is used to firmly bond the assembly of filter media and separator into the frame, ensuring a leak-free seal.

Primary Materials: Polyurethane Sealant Silicone Sealant Epoxy Adhesive Hot Melt Adhesive

The efficiency of currently available high-efficiency filters ranges from 99.9% to 99.999999%, and they can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.

For filters made of the same material, higher efficiency typically results in greater resistance and higher cost, while lower efficiency leads to reduced resistance and cost. Altering the air velocity will also affect resistance, efficiency, and the number of filters required, so appropriate selection should be made according to specific conditions.

As dust accumulates on the filter media, the resistance increases. When the resistance reaches an unreasonable level, the filter must be discarded. Sometimes, excessive resistance can cause previously captured dust to become dislodged and re-enter the airflow; when this risk arises, the filter should also be replaced. The resistance of a filter increases with higher airflow rates. By increasing the surface area of the filter media, the relative velocity of air passing through the filter can be reduced, thereby decreasing the resistance.
