G3 to G4 Pleated Pre-Filter with Paper frame
The G3 to G4 pleated pre‑filter with paper frame is presented as a disposable filtration element for coarse particulate removal. It is classified in the G3‑G4 range, meaning it captures particles roughly between 5 µm and 20 µm in size. Typical panel dimensions are 600 mm × 600 mm, and the frame is constructed from paper board, providing a lightweight yet rigid support for the pleated media. The filter media itself is a cellulose‑based paper that is pleated to increase surface area while maintaining a low pressure drop.
Typical filtration efficiency for a G3 grade is around 5‑10 µm and for G4 around 10‑20 µm, allowing effective pre‑filtration before finer stages. Under standard flow conditions a pressure drop of typical 100‑200 Pa is expected, and the element can handle a typical airflow of about 2000 m³/h. Service life is generally around typical 2000 hours of operation, after which the pressure drop may exceed acceptable limits. Installation can be horizontal or vertical in a standard 200 mm × 200 mm housing, and the pleated design aids dust loading distribution.
The filter is suited for HVAC systems, industrial air handling units and dust collection pre‑stages where coarse particles must be removed to protect downstream equipment. Facility managers, OEMs and maintenance contractors are typical buyers. Trade details such as MOQ, lead time and Incoterms are not disclosed in the listing and should be clarified directly with the supplier before ordering.

Sourcing G3 to G4 Pleated Pre-Filter with Paper frame from Suzhou Kosa Environmental Protection Co. Ltd.- Valve Department - China Import Guide
Before ordering, confirm the filter’s classification (G3 or G4), panel dimensions and housing compatibility with your equipment. Verify the supplier’s address in Suzhou and ensure that the harbour trust tier aligns with your import compliance requirements. Request a sample or technical datasheet that details the pressure‑drop curve and media composition to match your air‑handling specifications.
Logistics are commonly arranged on a FOB basis from ports in Jiangsu province, but the exact Incoterm, lead time and shipping schedule must be negotiated with the supplier. Payment conditions are not listed, so discuss acceptable terms such as T/T, LC or open‑account based on your risk assessment. Confirm the packaging method - typically bulk cartons with protective padding - to safeguard the fragile paper frames during transit.
To assure quality, consider a third‑party inspection focused on media integrity, frame dimensions and pressure‑drop performance. Ask the supplier for any available test reports or compliance documents, such as ISO‑9001 certification, even if not stated in the listing. Establish clear acceptance criteria in the purchase contract to address any deviations discovered during inspection.
