Import G3 To M6 Pleated Pre-Filter With Metal Support — Buy in Bulk from Supplier in China

Suzhou Kosa Environmental Protection Co. Ltd.- Valve Department in China offers a G3 to M6 pleated pre‑filter with metal support designed for air‑conditioning systems. The filter is classified as a pre‑filter, uses polyester fibre media and a frame that can be fabricated from galvanized steel, aluminium or ABS plastic. The supplier states a recommended final pressure drop of 250 Pa and a maximum continuous service temperature of 100 °C, with a typical pressure drop of about 150 Pa at an air velocity of 2.5 m/s.

The polyester fibre media provides good dust capture and chemical resistance, while the seven pleats per foot - roughly 40 % more than ordinary panel filters - increase surface area and extend service life. In the industry, G3 to M6 grades are common for pre‑filtration, delivering typical efficiencies of 70 % at 0.3 µm for the G3 grade. Standard panel dimensions are 600 mm × 600 mm, and a typical airflow capacity for this size is around 3400 m³/h at the specified velocity.

This product is mainly used as a pre‑filter in HVAC and air‑conditioning installations, where it protects downstream components from larger particles and moisture. Importers such as system integrators, HVAC contractors and equipment manufacturers typically purchase these filters in bulk and require confirmation of dimensions, frame material and pressure‑drop performance before finalising orders. Trade terms, including incoterms and payment conditions, should be negotiated directly with the supplier as they are not disclosed in the listing.
