Description
Corrosion Resistant – this Louvre Opener has an attractive black powder coated body and is corrosion resistant throughout.
How It Works – the stainless steel cylinder contains a mineral wax which expands with heat, causing the louvre vent to open. As the temperature falls the wax contracts, closing the louvre.
Opening Temperature Range – adjustable between 15 – 25*C / 59-77*F
Release Catch – allows the manual opening and closing of the louvre irrespective of the greenhouse temperature.
