Oil Water Separators should be installed to meet local environmental laws and regulations. We carry oil water separators at our Toronto and Guelph locations. Oil water separators help remove most of the oil contaminant from the condensate before discharging in to the sewage system. An Oil Water Separator will absorb the contaminant and allow you to drain the discharge directly. The carbon elements inside the unit must be replaced regularly, depending on the level of contaminant, approximately every 6-12 months. We have carbon kits available for all types of units.
