The Polyfilt BF 3.0 is a third generation uPVC bag filter housing engineered for increased operating pressure, better hydro pressure and a higher flow rate. It is the perfect replacement for stainless steel bag filter housings. Made from 100% uPVC material the bag filter housing has a higher capacity to withstand abrasive and harsh liquids, chemicals and challenging operating conditions. It will work better and last longer than your stainless-steel filter housings.

Filter bags are an integral part of bag filter systems, used to capture and remove solid particles from liquids or gases. They help reduce downstream contamination and improve process efficiency across industries like chemicals, food & beverage, pharmaceuticals, and water treatment.
What materials are Gopani filter bags made from?
Gopani filter bags are available in materials such as polyester, polypropylene and nylon, plus specially treated media for high temperature or chemical resistance depending on your application.
What Collar Options are available for filter bags?
Common collar options include steel ring collars, plastic collars and specialized welded collars to suit different housings and sealing methods.
What filtration ranges do Gopani filter bags cover?
Filtration ranges typically span from 1 micron to 500 microns depending on media and construction.
What flow rates can Gopani filter bags handle?
Flow rates depend on bag size, media and system design; we can help select the correct bag based on your LPM/GPM requirements.
Are Gopani filter bags reusable?
Some filter bags can be cleaned and reused depending on the solids and application; however, single-use bags are common for contamination control.
How do I know when to replace a filter bag?
Replace when you observe a significant pressure drop, physical damage to the bag, or when the recommended service life has been reached for your application.
