Import 3-Lugs Filter Cartridge — Buy in wholesale FOB from Supplier in China

The 3-Lugs Filter Cartridge from Zhejiang Xiao Yang Environmental Protection Sci-tech Co., Ltd. is a reusable industrial filtration element built around a three-lug locking mechanism for secure housing installation. Its wide pleat spacing allows debris to release during cleaning cycles rather than becoming permanently embedded, while the galvanized metal framework provides structural rigidity under differential pressure. The cartridge accepts multiple media grades including standard non-woven polyester fiber, typical spunbonded polyester, and PTFE membrane polyester variants. A rubber seal integrates with the lugs to prevent bypass leakage at the housing interface. The supplier notes washable media that supports multiple cleaning cycles, reducing replacement frequency in continuous-duty operations.

Material selection centres on polyester-based media rather than cellulose or glass fibre, giving the cartridge resistance to moisture and mild chemical exposure typical in painting and coating environments. The PTFE membrane option offers surface filtration with improved release characteristics for fine, agglomerating particles. Galvanized metal end caps and inner cores are standard construction for this product category, though stainless steel 304 or 316L are typical alternatives for corrosive atmospheres. The rubber seal compound is unspecified in the source data; buyers should confirm whether EPDM, nitrile, or silicone is fitted, as this determines temperature and chemical compatibility. Pleat density and media thickness directly influence dust-holding capacity and initial pressure drop, neither of which the listing quantifies.

Applications concentrate on shipbuilding paint booths, large steel structure coating lines, and container manufacturing facilities where overspray and abrasive dust loadings are substantial. The vacuum convey machine manufacturer reference indicates pneumatic conveying duty, where cartridges must withstand pulsed reverse-air cleaning without media fatigue. Target buyers are plant engineers, procurement officers for shipyards, and OEMs of dust extraction equipment. The supplier does not state MOQ, lead time, or incoterm availability; these require direct confirmation. Response rate and average response time data are absent, so buyers should anticipate variable communication speed when requesting samples or technical datasheets.

Zhejiang Xiao Yang Environmental Protection Sci-tech Co., Ltd. maintains its registered address at No. 198, Enlightenment Road, Xiaoshan District, Hangzhou, Zhejiang Province, postal code 311232, China. The Xiaoshan District location places the company within Hangzhou's industrial belt, an area with established environmental technology manufacturing clusters. The trust tier is listed as harbour, though the listing does not provide detail on what specific verification or audit protocol this tier represents. The response rate shows 0.00 with zero average response hours, indicating either a new listing, dormant account, or incomplete data capture rather than necessarily poor performance.

The company profile available from the source does not state year of establishment, employee count, annual revenue, factory floor area, or export licence details. No certifications such as ISO 9001, ISO 14001, or CE marking for filtration equipment are mentioned. Buyers should request a business licence, quality management system certificate, and product test reports directly. The product description emphasises painting and shipbuilding applications, suggesting the company's engineering focus lies in heavy-industry ventilation rather than HVAC or pharmaceutical cleanroom markets. Any claim of production capacity, major client references, or R&D staff size would need independent verification.
