The Simon Airtech Energy Saver Wallvent uses a unique system of innovative baffles and deflectors, which are integrated into the external cowl.

These allow sufficient equivalent free area to fully comply with Approved Document “F” 2006 of the building regulations whilst minimising draughts into the room and also prevents noxious gases being driven back into the room in cross wind situations.
