Find Out More About Our Filter Bags Range

Shaker Bags

Shaker filter bags use mechanical agitation to free the filter media of dust collected during filtration. This is a low-energy cleaning method.

Reverse Air Filter Bags

Reverse air filter bags use negative pressure to clean the filter media at given intervals, providing efficient, continuous dust collection.

Pulse Jet Filter Bags

Pulse jet filter bags are cleaned with a burst of compressed air, providing efficient continuous operation for industrial air filtration.

What are your dust collection requirements?

Our filter bags can be used for almost all types of industrial dust, including:

  • Light, medium and heavy dry dust and fumes
  • Hot gases and high temperature dust
  • Explosive dust
  • Welding fumes and smoke dust
  • Fine slag, smoke and thermal particles from plasma and laser cutting

As the dust filtration experts in Africa, we specify, design and supply the optimum filter bag and dust collector solution for your plant, factory or workshop processes. Some of the things to consider when specifying filter the best filter bags for your application include:

  • Process specifications (including temperature, pressure and instrumentation factors)
  • Footprint, weight, clearance restrictions
  • Surface area, length, diameter, design type of the filter
  • Flowrate requirements
  • The concentration and characteristics of solid dust
  • The viscosity, density, pH, volatility of liquid particles
  • Servicing and change out requirements and frequency
  • Safety and disposal requirements and issues
  • Overall hardware and filter costs

As a leader in dust filtration in Africa, we understand air pollution control equipment and how it interfaces with your plant processes or workflow. We ensure maximum filtration efficiency to allow you to operate at peak performance.

Filter bag construction

Filter bags from Envirox are the preferred choice in general industrial air filtration applications, with high collection efficiency for a range of dust and gas streams.

Our range of filter bags are available in both woven and non-woven materials:

  • Woven filter bags These filter bags are made of yarn with a definite repeated pattern. They are ideal for filters that use low energy cleaning methods such as shaking and reverse air filter bags.
  • Non-woven filter bags Non-woven filter bags are divided into felted and membrane bags:
    • Felted filters are assembled from fibres that are compressed into a mat and attached to a loosely woven backing material. This option is best used in more energy intensive systems such as pulse jet cleaning.
    • A membrane filter is a specially designed porous membrane (expanded polyfluorocarbon) bonded to support fabric. They offer high efficiency particle capture and are ideal in handling flue gas conditions with high moisture and high pressure drops.
