Simon Vent-A-Matic controllable ventilators are available in various model sizes. Each model is equipped with a diffusing rotor which helps to prevent severe draught and improve fresh air distribution within the room. The rotor also continues to operate whilst under its own inertia, even when air pressure on each side has been equalised.

The Vent-A-Matic RXL is a shuttered, slimline model designed for use in sash windows. It is capable of air movement of 4.71 litres/second, and suitable up to 5,997mm2 @ 1pa Equivalent Area.
