Aero Wall Anti Draught Ventilator
Installation Advice
- Anti-draught ventilators can be installed in new and existing walls
- To fit into an existing build, stitch drill and remove brickwork to one brick wide x either one or two brick high, and fit sloping away from the inner wall
- Large flanges around the external cowl and internal grille allow for minor irregularities to be covered easily and also adequate fixing
- An external cowl will push onto sleeve and can be silicone sealed to face or screw fixed.
