CleanAirTower General Ventilation

Energy-saving indoor ventilation system

The ventilation system CleanAirTower is used wherever local extraction does not work or is insufficient. It effectively protects employees and machines from fine dust. The purified air is recirculated. The device hardly creates any air turbulence, ensuring that no dust is distributed into clean areas. The CleanAirTower functions according to the displacement ventilation principle recommended by health and safety bodies.

  • Workshops where local exhaust ventilation is not possible
  • To complement local exhaust ventilation systems
  • Environments with changing sources of smoke and dust
  • Workstations, Workshops, Logistic and distribution centres
  • Minimization of heating costs due to air recirculation and air distribution
  • Increased safety with contamination-free dust disposal
  • No dust distribution into clean areas, as barely any air turbulence is created
  • Cost-effective installation or retrofit, as no ductwork is needed
  • Safe transportation and easy installation by crane eyes
  • Permanent operation by means of automatic dust disposal in dust collection bin
  • Automatic filter cleaning
  • Lifting eyes
  • 360° Inlet grill
  • Contamination -free dust disposal in one-way containers.
  • Slow, low-impulse air circulation
  • Displacement flow principle, recommended by health and safety bodies
  • System barely generates air turbulence
  • AirWatch
  • Extraction of ambient air via an integrated ventilator
  • The cleaned air is returned to the workspace by low level outlets
  • The warm cleaned air directs the welding smoke again towards the inlet grills and so, a slow air circulation and at the workstations is created.
