Hall layered ventilation
(production hall air cleaning)

The hall air purification system from Scheuch LIGNO is an effective solution for dust removal from production hall air. With layer ventilation, clean air is supplied to the welding workstation area through source air outlets close to the floor. This air feed causes the welding fumes to thermally rise towards the extraction ports. This ensures continuous air circulation, which significantly improves air quality. In summer, instead of air recirculation, fresh air can be added continuously and in a temperature-controlled fashion, which removes warm air from the hall. The use of layer ventilation in production halls is also possible in combination with extraction booms and extraction hoods.

Advantages of production hall layer ventilation

  • Application area from small to large production halls
  • Production hall heights from 3 to 20 metres
  • Can be combined with heat recovery systems

  • Suitable for heating and cooling operation

  • Fully automatic control of fresh air flows

  • Intelligent air flow control through fume and dust particle measurement

Low-velocity diffusers
