The Absolent type A•dust4F Dust filter is based on the latest and most efficient filter technology. With long service intervals, easy installation and servicing, this dust extractor can filter air volumes up to 2500m³/h.


  • The dust-laden air is sucked into the upper part of the filter. 
  • The heaviest dust particles fall directly into the dust container. 
  • The air is sucked into the filter cartridges, whereas most of the remaining particles stick on the outside of the cartridges. 
  • The cleaned air goes through the fan into the HEPA filter, with a guaranteed and consistent collecting efficiency of 99.99% arresting 0.3µm dia. particles. 
  • The HEPA filter has a pressure gauge that shows when the cassette should be replaced. 
  • Whenever the pressure drop across the filter cartridges exceeds a pre-set limit value, the valves in the tank for cleaning air open and a pulse of compressed air (approx. 4 Bar) is discharged into the filter cartridges from the cleaning nozzles (1 nozzle per filter cartridge). 
  • The compressed air pulse causes the dust collected on the filter surface to loosen and fall down into the dust container.


  • Down flow design to maximise particle separation.
  • Automatic reverse pulse cleaning allows continuous operation.
  • Secondary Hepa filter.
  • Integrated fan and motor.
  • Pressure gauges for reading pressure drop across the filters.
  • Air inlets, left or right hand side, Ø200mm.
