Buy & Import ePTFE air filter bag from Beijing Qianye Lotus Technology Co., Ltd. - Wholesale Supply

The ePTFE air filter bag is a high-efficiency dust collection element constructed with a surface layer of 3TO1-TEX expanded polytetrafluoroethylene microporous membrane bonded to a glass fiber fabric substrate. This composite structure enables surface filtration, capturing particulates on the membrane rather than within the substrate, which reduces pressure drop and extends service life.

The membrane has a pore size range of 0.1 to 0.5 microns, allowing for over 99% capture efficiency of fine dust. The glass fiber substrate provides mechanical strength while remaining flexible enough for standard baghouse installation. The material is chemically inert, resistant to acids, alkalis, and solvents, and operates continuously up to 260°C. Hydrophobic properties prevent moisture adhesion and reduce cake buildup.

This filter bag is used in cement kilns, steel mills, power plants, and waste incinerators where low emission and high durability are critical. Buyers include industrial plant operators, EPC contractors, and filter manufacturers. The product is sold by the unit or in bulk lots. Packaging is in sealed polyethylene with desiccant. Custom sizing is available upon request. Lead time and minimum order quantity are not specified.

The membrane has a pore size between 0.1 and 0.5 microns, enabling high-efficiency capture of submicron dust. This range is typical for industrial ePTFE filters and ensures surface filtration without deep penetration. Buyers should request a SEM image of the membrane to verify consistency.

Sourcing ePTFE air filter bag from Beijing Qianye Lotus Technology Co., Ltd. - China Import Guide

Before ordering, confirm the filter bag dimensions, top and bottom fittings, and gasket material match your baghouse design. Request a sample for fit and flow testing. Verify the membrane thickness and substrate weight are consistent with your operating conditions. Do not assume compatibility based on nominal size alone.

Lead time and minimum order quantity are not stated; buyers must confirm these directly with the supplier. Incoterms are unspecified - clarify whether FOB Qingdao, CIF, or DAP applies. Payment terms are likely advance payment, but confirm with the supplier. Shipping is typically by sea freight in sealed pallets with desiccant.

Upon delivery, inspect bags for physical damage, moisture, or contamination. Perform a visual check of the membrane for tears or uneven coating. Conduct a pressure drop test before installation. Retain packaging for 60 days. Request a certificate of material composition if required for compliance. No third-party test reports are provided unless requested.
