Import E11 To H14 High Air Flow Hepa Filter — Buy in Bulk from Supplier in China

The E11 to H14 High air flow HEPA Filter is a high‑efficiency particulate air filter designed for systems where a large volume of air must be treated within limited space. It is supplied as a HEPA filter with high airflow, constructed from glass fibre paper media and framed in either galvanized steel, stainless steel or ABS. The filter incorporates a hot‑melt glue separator and a polyurethane sealant, and is rated for a final pressure drop of 600Pa at the design flow.

Glass fibre paper provides a stable filtration matrix that retains particles down to 0.3 microns, meeting the EN 1822 classification for grades E11 through H14. Typical HEPA filters of this class achieve a minimum efficiency of 95% for E11 and up to 99.995% for H14, with a standard thickness of 30 mm and pleat spacing around 3 mm. In the industry, such filters are often supplied in standard dimensions of 600 mm x 600 mm or custom sizes, and are compatible with both steel and polymer frames.

These filters are commonly installed as final stage units in industrial clean rooms, air handling units and laboratory ventilation systems, where manufacturers and facility managers demand low resistance and reliable particle capture. Buyers usually request bulk quantities and specify incoterms such as FOB or CIF, with payment terms negotiated per contract. Because the supplier does not disclose MOQ or lead time, interested importers should confirm those details directly with the supplier before placing an order.
