Temperature-Responsive Greenhouse Vent Opener

Open and close a compatible greenhouse vent as temperatures change with a heat-responsive cylinder and spring mechanism.

Adjust greenhouse ventilation as temperatures change

• ✅ Reduce manual vent adjustment – The cylinder extends in warmth and retracts as conditions cool.
• ✅ Set the opening temperature – The adjustable mechanism has a listed starting range of approximately 15–25°C.
• ✅ Use it without electrical wiring – Temperature response operates the mechanism without a powered controller.

Confirm vent mounting and load compatibility before installation. Listed maximum vent weight is 7 kg; opening behaviour depends on adjustment and load. Do not heat the cylinder above 50°C or dismantle it.

• Specifications: aluminium and stainless steel; approximately 305 g. Package: vent opener, installation accessories and English manual.
