Duplex Bag Filter Bag Filtration Equipment

Product Details

Duplex bag filter introduction

INOCO-D duplex bag filter is the filter system which use two sets bag filters to achieve the effects, one work, one standby, or two filter are work in both. It is easy for install and clean and larger filter area will have more dirty amount, the more working time and the less clean times.

Reasonable structure, cover small an area of an area small, good sealing, large flow capacity  easy operation, the inside and outside of filter treatment is sand blasting or polishing processing, so the surface is smooth and good surface performance.
