The metal filter adopts multi-layer expanded aluminum foil mesh or stainless steel mesh as the special filter material for the filter, which is rolled into a wavy mesh shape and overlapped with each other at the correct angle; Multilayer folding expansion is an arrangement of different densities and pore sizes from coarse to fine, which allows objects to change their flow direction multiple times when passing through, increasing their efficiency.

Metal filter products have high ventilation capacity, large dust holding capacity, low initial resistance, and strong fire resistance; Long service life, economic reliability, and low operating costs; Lightweight plate structure, easy and safe replacement, convenient for users to operate on their own; There are galvanized frames and aluminum alloy frames to choose from; Non standard size devices can be customized according to user needs.
