Import Dust Filter Cartridge — Buy in Bulk from Supplier in China

The Dust filter cartridge from DFC Environmental Technology Co., Ltd. is a pleated media filter designed for industrial dust collection systems, with a nominal filtration efficiency of 99.5% at 0.3 microns. It features a polyester fiber media core with a polytetrafluoroethylene membrane finish, sealed with a nitrile rubber gasket, and fits standard 6-inch diameter housings. The cartridge is rated for continuous operation at 80°C and can withstand pressure differentials up to 12 kPa.

Typical industrial applications include woodworking shops, metal fabrication facilities, and cement processing plants where fine particulate control is required. The media structure allows for high dust loading capacity without rapid pressure drop, extending service life compared to standard synthetic filters. The cartridge is compatible with common dust collector models from manufacturers such as Festool, Nilfisk, and Aerus, and is often used as a direct replacement for OEM cartridges in systems requiring improved capture rates.

Buyers typically order in batches of 50 to 500 units, depending on production scale and filter change frequency. Packaging is in sealed polyethylene sleeves, with 10 cartridges per carton. Trade terms are commonly FOB Guangzhou, with lead times of 10 to 15 days after order confirmation. Buyers should confirm compatibility with their specific collector model before purchase, as housing dimensions and mounting configurations vary across brands.
