Import 7 Inch 200 Micron Filter Socks — Buy in wholesale FOB from Supplier in China

Xiamen Vablue Environmental's 7 Inch 200 Micron Filter Sock is a ring-top mechanical filtration media designed for aquarium and aquaculture systems. The filter bag measures 18 cm in plastic ring diameter and 43 cm total length, with a nominal pore size of 0.020 mm corresponding to 200 mesh. A finer 150 mesh variant (0.015 mm aperture) is also produced. The media is constructed from synthetic filter fibres with a surface treatment to prevent fibre shedding during extended submersion and backwashing cycles.

The seam construction uses hot-melt sealing rather than stitched or sewn joints, eliminating needle holes that could allow bypass of particulate matter. The supplier states this method prevents dirt spillage from seam gaps and avoids broken jumpers, a common failure mode in woven textile filters. The 200 micron rating positions this sock as a medium-coarse pre-filter or mechanical solids remover, suitable for capturing uneaten food, detritus and free-floating particulates before they reach biological filtration stages or clog finer media downstream.

Primary applications include marine and freshwater aquarium sumps, reef tank systems, koi pond filtration and light industrial liquid clarification where reusable bag filtration is economically preferred over cartridge systems. The 7-inch ring diameter suits standard 18 cm sump ports or custom filter housings. Buyers should confirm with Xiamen Vablue Environmental whether the stated dimensions include seam allowance, whether the 43 cm length is pre or post-shrinkage, and what the recommended cleaning protocol and maximum reuse cycle count are before ordering.
