Solar Automatic Window Opener for Greenhouse

Product Description Features:

Depending on the temperature, the piston of the cylinder moves and opens or closes the window automatically. As the temperature changes automatically, it maintains the best growing temperature and prevents your greenhouse from overheating. The automatic window opener does not require electricity or batteries, and with the instructions supplied, it can be opened easily and without problems. It can be clamped onto or screwed onto your greenhouse frame, providing perfect ventilation for your garden and greenhouses. The opening angle can be adjusted continuously by turning the cylinder.

Automatic Window Opener Replacement Cylinder: You can purchase a replacement cylinder from our store separately.

Suitable for Most Greenhouses: Do not use this opener in places where the temperature exceeds 50 °C (122 °F). Please make sure that your greenhouse window can be opened freely by at least 45 cm (18 inch). Do not exert excessive loads by locking or covering the window. Do not disassemble the cylinder. The opener cannot be stopped manually. Suitable for greenhouse windows up to 7 kg (from 7 kg we recommend the use of two window drives).

Durable Material & Easy Installation: Made of high quality of aluminum alloy for durability. Black Color powder coating for the frame, looks nice and is rust-resistant. Comes with a fitting accessory pack and a detailed manual for easy installation.

Automatic & Battery Free Solution: Automatically open or close the greenhouse vents as temperature rises or drops. Our automatic greenhouse window opener is solar energy sourced, and doesn't rely on batteries or electricity for operation.

Dual Spring & Strong Force: Double spring design can withstand the wind and rain, and is extremely strong. Lifts up to 15Lbs (7kgs), suitable for most greenhouse windows and vents.

Warm Tips: Maximum opening weight is 15Lbs (7kgs) for each unit. If the window weight exceeds 15Lbs (7kgs), we suggest using two vent openers or more to meet your demand. Compared with the single spring vent, our solar heat-sensitive roof vent opener adopts a double spring design, which has a stronger thrust force and is more solid. In addition to ordinary areas, it can also be applied in windy mountainous areas, resisting wind twist and bringing much convenience to you. Our greenhouse vent automatic opener responds to temperature changes, efficiently regulating your greenhouse's internal climate. As the temperature rises, the gas-filled cylinder expands, gently pushing the window open. Once the temperature cools down, the spring mechanism closes the window smoothly. Crafted from aluminum alloy with a black color powder coating, this window opener guarantees long-lasting performance and is built to withstand outdoor weather conditions. The corrosion-resistant materials ensure reliable performance season after season. Operating between 15°C to 25°C (60°F - 77°F), the greenhouse window opener adapts to various weather conditions, helping to maintain an optimal growing environment inside the greenhouse. Installing the greenhouse vent opener is quick and straightforward with the provided clamps and screws. It fits most greenhouse windows and seamlessly integrates with roof vents for houses, making it a versatile choice for different setups.
