Description

With a flange type suitable for EPDM roof covering, this Ubbink OFT/4 flat roof vent/terminal can be used in soil and vent systems and mechanical ventilation or passive/natural applications. Featuring a special low air resistance cowl, this roof vent terminal offers a pressure/airflow resistance of less than 1.0 Pascal at 225m³/h.

The stack pipe has an integrated collar and separate aluminium flange for use with both felt and asphalt while the pipework above the roofline is twin-walled and integrates a condensation drain. The stack cap is fixed mechanically so that is it sturdier when installed in extreme weather conditions, but it can be detached for servicing purposes. The flange enables termination through a flat roof to ducting with a 131mm diameter.
