Description

 

Automatically opens and closes the roof vent/window when temperature changes. The opener has a metal cylinder containing a mineral which expands when heated. This pushes a piston that opens the vent. As the temperature cools, the mineral shrinks and a spring closes the vent and resets the piston. The opening and closing of the vent is gradual allowing just the right amount of air flow for cooling.

- Starts to open at 15-23 degree
- Fully open temperature 35 degree and above
- Open temperature can be adjusted
- Fully open distance 45cm
- Maximum open weight 7kg
- Comes with installation instructions
