Ubbink OFT Flat Roof Vents

The OFT terminal range is suitable for use with soil & vent systems and for both mechanical and natural (passive) ventilation installations.

The OFT/4's have a special low air resistance cowl - the pressure/airflow resistance is <1.3 Pascal at 225m³/h. The pipework above the roofline is twin walled and incorporates an integral condensation drain.
