These filters have multiple layers of wire mesh. While single-layered wire mesh filter is an ideal solution for various challenges, it has a limitation to the porosity it can offer. So, in the situation where wire mesh filters are required with lower micron ratings, multi-layered wire mesh is the solution. The multiple layers are bonded together to enhance the retention of particulates.

FAQs

What are filter bags for?
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.
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.
Common collar options include steel ring collars, plastic collars and specialized welded collars to suit different housings and sealing methods.
Filtration ranges typically span from 1 micron to 500 microns depending on media and construction.
Flow rates depend on bag size, media and system design; we can help select the correct bag based on your LPM/GPM requirements.
Some filter bags can be cleaned and reused depending on the solids and application; however, single-use bags are common for contamination control.
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.
