Description

This very smart autovent uses energy from the sun and surrounding air.
The autovents strong metal tube contains a mineral wax which expands with heat. This pushes a piston which opens the vent via a balanced linkage. As the temperature rasises, the vent will open. As the temperature drops, the wax shrinks and a strong stainless steel spring closes the vent and resets the piston.

Things to remember:

-Do not use this opener anywhere the temperature will exceed 60° (140f)
-Please ensure your greenhouse window can be opened freely by at least 45cm (18")
-Get the very best from your greenhouse plants and veggies - don't leave it to chance!

Package included:

- Automatic window opener x 1
- English manual x 1
