Product Description This Airflow round stainless steel external grille offers a more aesthetic appearance than more traditional plastic grilles. They are more weather proof and are not affected by ultra violet rays like some plastics can be. This grille complies with the requirements of the Domestic Ventilation Compliance guide 2010 that states terminal opening is a minimum of 90% of the free area of the ducting being used. This free area ensures that the grille is not creating too much pressure for the fan to push against, the fan would not be as efficient were the free area of the grille less than 90%. This fan is suitable for use with most mechanical extractor fans including our iCON, QuietAir, Loovent, Maxivent, Supervent and Aventa range of fans. It can also be used with all our Duplexvent Mechanical Heat Recovery Units (MVHR). This grille comes with louvers to prevent small mammals and birds from accessing the ducting attached to it, these louvers are stylishly covered by the bull nose design cowl. It can be attached to rigid pipe or flexible pipe and is screwed to the external wall This cowl has been designed to be inserted into 150mm flexible or rigid ducting. The grille can be cleaned using any stainless steel cleaner. Box Contains Stainless Steel Grille
