Duplex Bag Filter Housing

About Duplex Bag Filter Housing

Duplex Bag Filter Housing

We have established ourselves in presenting a wide range of Duplex Bag Filter Housing. This product is designed for continuous process line, where one housing is under operation and another one is stand by, which can be changed by 3-Way ball valves or Butterfly valves without interruption of process. this product is easy for maintenance without stoppage of flow. We design suitable up to 30 Nos. filter Bag elements in single housing. We provide high quality Products with wide range of flow capacities up to 1500 M³/Hr. It is used in Fine filtration, wherever required.

 

Operation: -

This Product is preferably used to separate hard contaminants from liquid, gas and powder. Contaminated fluid or gas or powder is entered through inlet connection and scattered equally around the filter Bag and passed through filter Bag from inside to outside. Solid elements are collected from inside of Bag. And filtered Fluid or gas or powder exit from outlet connection. It is easy to remove and clean in a reliable manner without making any extra efforts. 

 

Features:

Continuous Filtration for Critical Processes

Duplex Bag Filter Housing enables non-stop operation by allowing easy switch-over between chambers with an integrated changeover valve. This design minimizes downtime during bag changeouts, making it suitable for industries where uninterrupted filtration is essential, such as water treatment, pharmaceuticals, and chemical processing applications.


Superior Corrosion Resistance and Durability

Constructed from premium-grade stainless steel 304 or 316, these housings provide excellent resistance against corrosion, even under challenging chemical and temperature conditions. Externally and internally polished surfaces prevent buildup and make cleaning straightforward, extending equipment lifespan and maintaining optimum performance.


Flexible Filtration Options

Users can customize filtration by selecting from a variety of bag materials (PP, Polyester, Nylon) and gasket options (EPDM, NBR, Viton) to suit specific process requirements. The system supports filter ratings from 5 to 100 microns, accommodating diverse industrial and processing needs with exceptional filtration efficiency.
