Self-Regulating Greenhouse Vent Opener for Roof Vents

Automatically Opens and Closes Based on Temperature

This AV01 residential roof vent opener is a simple, non-electric solution for maintaining optimal airflow in backyard greenhouses. It uses a temperature-sensitive wax mechanism to open and close vents automatically, without any wiring or power source.

Adjustable Temperature Range for Custom Climate Control

Designed to activate between 17°C and 24°C (adjustable), the mechanism expands to lift the vent when temperatures rise and retracts as it cools. The AV01 model can lift up to 14kg, making it ideal for standard greenhouse roof vents.
