150mm Round Ceiling Extract Plastic Duct Fire-Rated Valve

The 150mm Round Pipe provides superior airflow performance when compared with the 150mm Rectangular Duct and should always be considered first option if space allows. The 150mm Round Pipe is the most efficient ducting system in this range and can be used for high power cooker hoods of 800m3/h and above and long ducting runs where pressure drop needs to be minimised.
