Products description

Automatic Vent Opener
for cold frames and Greenhouse roof vents

The autovent always provides the correct climate of the cold frame or Greenhouse and ensures the optimum ventilation at all times. Adjustable from ~ 15 °C to ~ 30 °C. The autovent is attached to or disconnected by pressing the opening arms together.

Lifting capacity: ~ 7 kg
Adjustable: approx. 15 ° to approx. 30 ° C
Opening width: ~ 45 cm
Warranty: 2 years

A controlled climate and a temperature range between ~ 15 °C to ~ 30 °C ensure a safe growth of most plants. It may happen, however, that these limits are exceeded. Are you always at home when the sun shines too hot? Do you always pay attention to ventilation, which is important for the soil?

The automatic window opener takes care of this responsibility. The temperature can be controlled from ~ 15 to 30 °C by simply turning the cylinder. The temperature-depending expansion fluid contained in the cylinder opens the vent with a lifting capacity of up to 7 kg. Opening width: ~ 45 cm. Two steel springs will rapidly close the vent in case of the slightest temperature drop. This is very important when using PVC-sheets since the counter-pressure is very low.

Protected at last against moody weather, especially in the case of delicate plants.
