Bayliss Automatic Louvre Opener

Temperature adjustable – you can set the opener to start opening the louvre from 15-18*C, with a maximum opening at approximately 30*C.

Easy Fitting – it is supplied with a back plate enabling you to fit the louvre opener using the existing holes on the majority of louvre vent systems. 

One of the most important aspects of greenhouse growing is having sufficient ventilation. Bayliss have designed their autovents take the guesswork out of this all important operation, ensuring accurate, continuous venting 24 hours a day. 

This autovent works as it includes a strong metal tube that contains a mineral wax which expands with heat. This pushes a piston which opens the auto vent via a balanced linkage. As the temperature drops, the wax shrinks and a strong stainless steel spring closes the vent and resets the piston.
