All greenhouses require ventilation. Take the guesswork out of greenhouse ventilation with the Bayliss vent opener that operates automatically on solar power.
The Bayliss Standard Triple Spring solar powered roof vent opener has been designed for aluminium or timber framed hinged vents measuring up to approximately 2 ft square (60cm square) and this vent opener can be used in all greenhouses.
The Bayliss vent opener fits neatly, close to the glass/polycarbonate, consequently taking up less head room than a normal stay on a roof vent. The unit is 11 1/2" long (excluding the hexagon adjuster seen in photo on the right of the autovent). This model will operate a vent exerting a load of 14lbs (6kgs) at the point where it is attached to the vent, and can be set to start opening the vent at temperatures between 55F (12C) and 75F (25C), giving a maximum vent opening of approximately 12".
