【Temperature-Dependent Ventilation】Our automatic greenhouse vent opener responds to temperature changes, thereby effectively regulating the indoor climate in your greenhouse. As the temperature rises, the gas-filled cylinder expands and gently pushes the window open. Once the temperature has cooled, the spring mechanism gently closes the window.

【Wide Temperature Range】The greenhouse window opener operates between 15°C and 25°C (60°F-77°F), adapting to various weather conditions. The automatic window opener allows for full opening at temperatures above 30°C (86°F) and offers a maximum ventilation distance of 45 cm (18 inches) for optimal air circulation.

【No Power Required】Our automatic greenhouse window opener is fully automatic and does not rely on batteries or electricity for operation. No additional power source is required, saving you money and reducing environmental impact.

【Premium Quality】This window opener made of iron and stainless steel ensures long-lasting performance. The automatic vent opener meets the demands of greenhouse environments, ensuring it will be your reliable gardening companion for many years.

【Easy Installation & Compatibility】Installation of the greenhouse vent opener is quick and easy with the included clamps and screws. It fits most greenhouse windows and can be seamlessly integrated into roof vents, making it a versatile choice for various configurations.
