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

The G3 to M6 Pleated Pre‑Filter With metal Mesh is a pre‑filter designed for air‑conditioning systems. It uses a polyester fibre media supported by a metal mesh and is offered with frames of galvanized steel, aluminium or ABS. The supplier specifies a recommended final pressure drop of 250 Pa and a maximum continuous service temperature of 100 °C. The product is classified in the G3‑M6 efficiency range, covering common pre‑filtration grades.

Polyester fibre provides a balance of dust holding capacity and airflow resistance, while the metal mesh reinforces the pleated element and protects against mechanical damage. In the industry, pleated pre‑filters of this class typically have a thickness of about 25 mm and are supplied in standard 600 mm × 600 mm panels, although dimensions can be customised. Typical pressure drop at a face velocity of 2.5 m s⁻¹ falls between 150 Pa and 300 Pa, matching the supplier’s 250 Pa recommendation. The frame options allow selection based on corrosion resistance requirements in humid or chemically aggressive environments.

These filters are commonly installed upstream of finer HEPA or electrostatic filters in commercial HVAC units, data‑centre cooling systems and industrial ventilation where particle removal of 5 - 10 µm is required. Buyers such as facilities managers, HVAC contractors and OEMs usually request verification of media composition, pressure‑drop performance and frame material before placing bulk orders. Because the listing does not disclose minimum order quantity, lead time or payment terms, the importer should confirm those details directly with the supplier.

Suzhou Kosa Environmental Protection Co. Ltd.- Valve Department is located at No. 625 Huayuan Road, Zhangpu Town, Kunshan, Suzhou, Jiangsu Province, China. The company is listed with a harbour trust tier and currently shows a response rate of 0 % and no average response time recorded. It operates within the environmental protection sector and focuses on components for air‑handling equipment, including pre‑filters and related valve products. The public profile does not disclose production capacity, certifications or export history.

The supplier’s catalogue highlights the G3 to M6 pleated pre‑filter as part of its air‑conditioning product line, but it provides no specific information on minimum order quantities, lead times or payment conditions. Potential buyers should therefore request a formal quotation that clarifies those trade parameters and any applicable quality assurance documents. The company's presence in the industrial hub of Suzhou suggests access to established logistics networks for bulk shipments. Verification of the supplier’s current operational status is advisable before committing to a contract.
