PRE ORDER MAY. - Greenhouse Automatic Vent Opener

The Automatic Vent Opener was designed to automatically control the temperature and humidity levels in your greenhouse. It provides additional ventilation for all MAZE Greenhouses, making gardening easier. As the air inside the greenhouse warms, the Automatic Vent Opener enables the vent to open gradually allowing the correct amount of airflow into the greenhouse until the optimal temperature is reached. The vent arm was designed with a metal cylinder containing wax which expands when heated to push a piston, which raises the window as the air gets warmer, then contracts as it cools, closing with the use of a spring and resetting the piston. The Automatic Vent Opener operates without the use of electricity.

Opens roof vent automatically as temperature warms for air circulation and heat relief, closes when temperature cools Solar powered, heat activated - start opening point: 12°-15°C Mechanic system - no electricity is needed Suitable for all MAZE greenhouses with roof vents Easy to install
