SWEETVENT Stack Odour Control


The SweetVent® utilizes the positive pressure generated inside the vent line to push the contaminated air up through the unit. The odorous compounds are absorbed by the CENTAUR® HSV carbon allowing clean air to pass through the end of the SweetVent into the atmosphere. The pressure surges within the vent line are sufficient to overcome the pressure drop across the carbon bed. When odour breakthrough occurs, only the carbon needs to be replaced. Refill bags of Centaur HSV carbon are available from Continental Carbon Group.
