Greenhouse automatic vent openers

Automatic Vent Openers (also known as auto vents) automatically open and close vents in your greenhouse – whether roof vents, side vents or louvre windows.

Automatic vent openers do not require electricity. Rather, the openers have a metal cylinder which contains a mineral wax that expands when heated. This in turn pushes a piston that opens the vent. As the temperature cools, the mineral wax shrinks and a spring closes the vent and resets the piston.

Automatic Vent Openers are made from durable materials so you will receive the benefits of the Automatic Openers for years to come.
