Are your exhaust air flows damp and contaminated with gases? Our scrubbers provide safe and efficient cleaning.

Venturi scrubber & absorption scrubber

Exhaust air cleaning

Our HNA Venturi scrubbers reliably remove dust from damp exhaust air flows. Clean gas dust content of below 5.0 mg/m³ can be achieved with reasonable energy expenditure. Scrubbing liquid is cleaned via automatic belt filters or time-controlled outlet valves, which empty automatically during the operation of a partial load. The FKW absorption scrubbers reduce acidic, basic and gas-laden parts in exhaust air to permitted levels, for example for ammonia, amines and HCl. The dosing of reagents and partial discharge take place automatically.

Advantages for you

  • Safe separation of moist and sticky dusts
  • No risk of condensation
