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).
Available in epoxy powder coated white or brown as standard.
