Odour control involves venting large volumes of air from such as food preparation and chemical plants and passing the contaminated air through bio-scrubbers before exhausting it to atmosphere. If there is heavy particulate loading in the airstream, a self-cleaning fan would be recommended. In chemical plant applications, a more corrosive resistant impeller design may be required to ensure long-term durability.

Relevant construction materials:

  • Carbon Steel
  • Stainless Steel
  • Coated Carbon Steel
  • Hastelloy
  • Titanium
