Product description

This unit is designed for automatic louvre control, fitting within the frame size of the louvre. This allows the louvre to be mounted in virtually any position in the greenhouse. The release catch allows manual opening and closing of the louvre irrespective of greenhouse temperature. It has an attractive powder coated body and is corrosion resistant throughout. Ventilation is essential in a greenhouse to promote healthy, disease free growth. We were the originators of automatic ventilation for greenhouses and have been at the forefront for some seventy years. We now manufacture an opener to suit most roof, side and louvre vents. All our openers, suitable for both aluminium and timber greenhouses, are fitted with a black cylinder which enables the opening temperature to be adjusted between 15ºC and 25ºC, and are covered by a 2 year guarantee.

As the title.

Well built, simpler to fit than I expected and works well.

Only thing I changed was the plastic 'pin' which connects the vent arm to the push rod - I was finding when it was 25 degrees + the plastic pin was bending and the securing cap came off which the stopped the louvres closing.

Replacing the pin with a thin bolt and nut kept operation the same and overcame this problem

Easy to fit with clear instructions, works perfectly ensuring good air circulation. I would recommend fitting them to all the louvre windows

I couldn't review this sooner - the weather was too cold for it to operate! Now things have warmed up a bit, it is working well. It was simple to fit to an aluminium greenhouse, it is well made & well finished. The instructions are clear. The adjustment knob works easily (and effectively). I fitted it as a replacement for an old auto opener (the hardest part was getting the old opener off!). Overall a well designed & well made product - it should last for years.

The opener works well. I did need to manufacture a simple bracket to make it fit my installation, but not a problem.

A real labour saver. Ensures the greenhouse is kept at a reasonable temperature. Easy to fit to the vent purchased at the same time and works well.
