Top-Level Filtration for Tough Jobs
Angran was founded in 2018. Our factory covers 4,000 square meters with 20 skilled workers. Our PTFE membrane filter bag is a premium choice for demanding filtration tasks.
We apply a thin PTFE film to the bag's surface. This film has microscopic pores that capture dust down to the micron level. The surface is very smooth, so dust does not stick, making cleaning easy. This bag is ideal for high moisture, high corrosion, and strict emission environments. We support OEM orders. Minimum order is 1 piece. Non-worn parts have a 1-year warranty.
