Carbon filters

Activated carbon filtration for odours, fumes and gases.

From carbon impregnated panels and bags for low-level supply air odours, to bonded carbon panels, Discarbs and carbon rigid filters for heavy odour and gas loads on supply or extract.

Questions

Useful answers before you specify

For low, non-critical odours such as supply air from busy roads or car parks, carbon impregnated panels or bags are usually enough. For cooking odours, exhaust fumes or process gases, use bonded carbon panels or carbon rigid filters. For heavy loads such as hydrogen sulphide or ammonia, Discarbs hold 18kg to 67kg of carbon.

Technical help without the hard sell
