JQA Single Bag Filter Housings

Introduction
The JQA Single Bag Filter Housings adopts a top-inlet, bottom-outlet filtration method, featuring integral casting, compact structure, and durable design. The filter top cover, fastened by bolts and integrally cast, can withstand higher pressure. The top cover directly seals and presses against the filter bag, providing better sealing performance with absolutely no bypass leakage. Since the liquid medium enters the filter from the top and flows downward, the liquid is evenly distributed across the entire filtration surface of the filter bag, keeping the fluid distribution across the entire layer basically constant. This minimizes the negative impact of turbulence on the filter bag, resulting in good filtration efficiency and long service life.
Features
Integral casting, compact structure, durable design
Top cover directly seals and presses against the filter bag with double O-ring seal, absolutely no bypass leakage
Top cover opens and closes quickly and easily, adaptable to different opening directions
Filter bag replacement is safe and convenient; filter legs are adjustable
Filtrate flows in from the top cover, reducing turbulence, improving filter bag efficiency and service life
Working Principle
Material flows from the bag filter inlet into the filter bag. Particles larger than the filter bag's pore size are trapped on the inner surface or within the filter bag. Purified liquid passes through the filter bag from inside to outside and flows out from the bag filter outlet.
