Mk 7 Super Autovent Similar in design to the Mk 7 model but larger (15½" 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 60F (16C) and 75F (25C).

## Features

- Extremely reliable automatic vent opener designed to lift very heavy double-glazed windows weighing up to 35lbs
- Bolts on to aluminium greenhouses (fixings supplied) - for wooden greenhouses it is attached by wood screws (not supplied)
- An aluminium unit approx. 39cm long in an White finish to complement modern conservatories
- Operated by an aluminium finned cylinder containing a mineral wax which expands with heat - this pushes a piston causing the vent to open
- As the temperature falls the wax contracts and a strong stainless steel spring closes the opener
