Similar in design to the Mk 7 model but larger (151/2″ overall length), the Mk 7 Super Autovent is suitable for operating heavy double glazed conservatory and greenhouse vents, lifting a load of up to 15.9 kg (35lbs).
The super autovent has a unique, ultra strong, finned aluminium power tube with internal and external fins to give more efficient heat exchange between the wax inside the tube and the surrounding air. It opens a vent exerting a load of up to 15.9 kg (35lbs) approx. 15 inches at full stretch and operates between 60oF (16oC) and 75oF (25oC).
