The Mk 7 Super Autovent is suitable for operating heavy double glazed conservatory and greenhouse vents. The super autovent has a unique, ultra strong, finned aluminium power tube with internal and external finns 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). Available epoxy powder coated white or brown as standard. |
Over the years, the expansion fluid inside the autovent cylinders is used. It is no longer elastic enough to open the vent sufficiently. In order to ensure a good ventilation of the greenhouse, the cylinder must be replaced.
