Detailed Introduction

The coarse filter is mainly made of carbon steel, low alloy steel or stainless steel, and can be denoted by C, M and S respectively. The coarse effect filter is a kind of primary effect filter, which mainly performs coarse filtration on dust particles, thereby reducing the sharing of the medium-efficiency and high-efficiency filter, thereby achieving the desired filtering effect.
