Rotary Vent-A-Matic 102

The Vent-A-Matic is a durable and effective in-glass ventilator that can solve most ventilation requirements. The 102 Rotary Vent is equipped with a diffusing rotor which helps to prevent severe drought 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.
