Industrial central vacuum cleaning systems for the simple, safe and efficient disposal of dust, bulk material and production residues.

VAC & NetVac® – industrial central vacuum cleaning systems

Industrial central vacuum cleaning

Industrial central vacuum cleaning systems are more efficient than mobile industrial vacuum cleaners. These central vacuum cleaning systems ensure that any removed material, such as dust, bulk material or production residues, are collected in a central location. As a result, waste disposal is much simpler. The collected material can be loaded into designated containers, such as cardboard or metal boxes, big bags or truck containers. There is no limit to the number of cleaning points that can be installed. Rotary blowers are used to facilitate safe and blockage-free operation of the commercial central vacuum cleaning system as well as transport of the waste material over long distances.

  • Safe und blockage-free operation
  • Cleaning of the entire production area
  • Constant availability
  • Central disposal location outside the production area
  • No disruptive mobile industrial vacuum cleaners in the production area


  • 24/7 operation
  • Low clean gas dust content <1.0 mg/m³
  • SoftClean system for automatic cleaning
  • Discharge units with Easy Clean feature
  • ATEX-compliant design
  • Constructive explosion protection
  • Constructive fire protection


  • Tire / Rubber

    Riedel Filtertechnik offers a wide range of standard and individual solutions for process exhaust in tire production – from dust extraction to odour emission reduction. Our specially designed dust extraction systems keep emissions well below the limit values of 10 mg/m³. That typical smell of rubber is eliminated by our COPLAS clean cold plasma air cleaner system in an energy-efficient and reliable way. So, tire production can become more sustainable than with conventional technologies.

  • Food

    Cereals, oil or milk powder – food production is characterised by the variety of food products alone. Countless process steps including extrusion, drying, cooling or product packaging are completed for their production. As a result, dust or strong-smelling odour emissions are inevitably released into the environment and are subject to strict limits. We help our customers to comply with these emission limits by offering a wide range of products – from dust removal to industrial odour control systems.

  • Pet food

    Pet food production involves numerous process steps – extrusion, drying, cooling, machine extraction or even wet food cooking. During the processing of wet and dry pet food, dusts and odorous substances are released into the exhaust air, which can pollute the environment. Riedel Filtertechnik offers a wide product portfolio with individual solutions for pet food production. We cover everything from dust extraction and dedusting of conveyors, extruders and dryers to the reduction of odour emissions.

  • Compound feed

    In compound feed production, odour-intensive substances are often added for specific recipes. As a consequence, odour emissions are produced that can pollute the environment. Grinding fine, dry ingredients and pelleting also produces dust emissions, which can be controlled using our filter systems. Our COPLAS clean cold plasma technology for air cleaning reduces any odours sustainably without any chemicals or waste products.
