Automatic Greenhouse Roof Vent Opener
otherwise known as an Autovent
Universal Fitting to any Greenhouse
All Fittings and Instructions included
Made in the UK
This autovent opens and closes the roof vent on your greenhouse by using a wax cylinder, which expands and contracts according to the temperature. This moves the ram mechanism to open and shut the vent as required. This can be set to open between 15C - 25C (59F - 77F), and will lift a vent weighing up to 14kg (that copes with all domestic greenhouses).
