This is a 127mm (5 inch) core drill wall ventilator that comes with an anti-draught baffle. Without the baffle you get a free airflow area of 100cm². Put the baffle in place and it reduces the airflow to 70cm² - handy for controlling draughts. The ventilator itself has a 27kW net rated input (when the baffle is not fitted). The standard length of the tube is 350mm - long enough for standard cavity walls. The ventilator has a white internal grille and external cowl, but you can also get other cowl colour options.
