GY High Efficiency Air Filter

The GY High Efficiency Air Filter supplied by Suzhou Kosa Environmental Protection Co. Ltd.- Valve Department is a polyurethane‑sealed separator intended for cleanroom and industrial ventilation systems. It complies with EN1822 classifications Y10, Y11, Y12, H13 and H14, delivering efficiencies from 85 % to 95.995 % at the most penetrating particle size and 99 % at 0.3 µm for the higher grades. The filter can operate continuously up to 70 °C and tolerates 100 % relative humidity. The supplier recommends a maximum pressure drop of 600 Pa under rated conditions.

The filter body uses a polyurethane sealant that protects the media from moisture ingress and maintains structural integrity at elevated temperatures. Typical high‑efficiency filtration media for this class are classified between F7 and F9, providing a balance of particle capture and airflow resistance. In the wider industry, frame sizes of 320 mm × 320 mm × 220 mm are common for compact installations, while larger units such as 630 mm × 630 mm × 220 mm serve higher airflow demands. Standard airflow ratings range from 500 m³/h at 180 Pa to 3000 m³/h at the same pressure, depending on the chosen size and efficiency grade.

These filters are widely used in pharmaceutical manufacturing, electronics assembly and power plant ventilation where low particulate levels are mandatory. Procurement typically involves bulk cartons of filtered units, with packaging supplied in standard cardboard boxes; exact minimum order quantities, lead times and incoterms must be confirmed directly with Suzhou Kosa Environmental Protection Co. Ltd.- Valve Department. Buyers should request test certificates that verify EN1822 performance and confirm that the polyurethane sealant meets their chemical compatibility requirements.
