Product Description

The Automatic Vent Opener was designed to automatically control the temperature in all Rion Greenhouses. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of air flow into the greenhouse and closes when the optimal temperature is reached. The vent arm was designed with the use of natural wax that expands as the air gets warmer, to push a piston which raises the window, then contracts as it cools, closing with the use of a spring. The Automatic Vent Opener operates without the use of electricity.

  1. so glad we have them

    Posted by Unknown on 9th Jul 2015

    we have an 8X16 hobby green house with 3 window vents. we have the automatic openers on all windows and really like them. Our only complaint is that two didn't winter well and had to be replaced this spring.
