Filter 40 RAV


  1. Use of the filter equipment
  2. Basic  technical details
  3. Main connection dimensions


Filtration equipment is designed for extraction and filtration of dry metallic and non-metallic dust and small particles. They are suitable for suction of dust arising from the various technological processes. The ability to use filtering equipment must be consulted with the manufacturer. On this basis, appropriate filter membrane is chosen. The RAV filter 40 is designed to work in an environment without the danger of explosion when in  normal temperatures of the surroundings ranging from -10 ° C to +40 ° C. Extractors are placed indoors or under shelter at least provide protection against the weather. If the dust is sucked, which can in certain circumstances be explosive must be installed outside the filter process line. Best in outdoor environment under a shed. The location of the investor decides on the basis of existing legislation. The filter 40 is equipped RAV with a system of regeneration by atmospheric air. This means that after a certain time the filter membrane will automatically under go re-blowing which leads to purification. If coarse particles are sucked into the filter it could lead, under certain circumstances, to poor regeneration of the filter membrane and the gradual clogging of the entire filter housing. The filter should therefore suck air mass devoid of coarse debris. As the first stage of filtration before this filter, a separator is designed to eliminate these particles.
Example of use: suction filtration and technological lines for the production of pellets from straw.
