Canfil is a fully automatic, continuous system that works according to the principle of surface filtration. A wedge wire screen or metal fibre fabric is used for filter candles which retain particles of different sizes on their surfaces. After the pre-determined degree of contamination has been reached, the filter candles are cleaned by backwashing a small quantity of filtered medium, while filtration continues during backwash.

Features and Benefits
  • Backwash without interrupting filtration.
  • High operating pressure up to 40 bar possible.
  • Completely closed system.
  • High throughput up to 10.000 m³/h.
  • Low investment costs.
  • Low pressure drop.
  • Filter fineness of 50 µm to 3.000 µm.
  • Long standing times between backwash procedures.
  • Minimal operating costs.

  • Pulp and Paper
  • Fibre Industry
  • Chemical Industry
  • Water Treatment
  • Textile Industry
  • Steel Industry
  • Automotive Industry
  • Power Plants

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.
