Filtration of welding/grinding fumes and oil mist


Årjängs Verktygsindustri AB manufactures tools, machines, peripherals and aids for industry. Since Årjängs Verktygsindustri was established in 1981.

Our clients range from small businesses to major industrial groups and operate in a wide sector from the clothing industry to heavy processing industry and enterprises selling services.

The challenge

Welding and grinding for dry applications, oil mist captured via hoods for tempering furnaces as well as local extraction for processing machinery are part of the operations of Årjängs Verktygsindustri. They reached out to Plymovent because they needed an installation that improved the air quality at their workshop.

The solution

Welding and grinding fumes from dry application are captured directly at source via Plymovent’s local extraction, the KUA and the MultiSmart extraction arms. These fumes are then filtered in a self-cleaning filtration unit, Plymovent's MultiDust® Bank B-4.

Oil mist is captured via local extraction and via hoods for tempering furnaces and filtered using a five-step oil mist filter, Plymovent's MistEliminator ME-32.

Main benefits

  • The filtered, heated air passes through a heat exchanger before being recirculated to the workshop room. All filters and units are frequently controlled for optimal functioning
  • Efficient filtration of welding and grinding fumes
  • Parallelogram arm ensures one touch smoothness and stays firmly in place
  • External arm chassis provides strong support and outstanding stability, support and balance
  • Comply with health and safety standards
  • Minimise health risks in the workplace
