Solar Greenhouse Vent Opener - Automatic Window Opener for Greenhouses

The automatic greenhouse vent opener is a durable and eco-friendly solution for maintaining the ideal temperature in your greenhouse. Crafted from high-quality steel, this opener features a black powder coating that not only looks great but also protects against rust.

Powered by solar energy, this opener requires no electrical power, making it a cost-effective and environmentally friendly choice. It automatically opens or closes the greenhouse vents as the temperature rises or falls, ensuring your plants receive the optimal growing conditions.

To prevent overheating, the automatic window opener is designed with an overheating protection feature. This helps maintain the ideal temperature range for your greenhouse, creating the perfect growing environment for your plants.

For enhanced durability and stability, the opener is equipped with double springs that can withstand strong winds. The powerful mechanism can lift up to 15.4 lbs (7 kg), making it suitable for a wide range of greenhouse windows and vents.

Installation is a breeze, thanks to the included fitting accessory pack and detailed manual. The start-open temperature can be adjusted from 15°C to 23°C (59°F to 73.4°F) by rotating the cylinder clockwise to lower the temperature or counterclockwise to increase it. When the temperature reaches 33°C (91.4°F) or above, the window will fully open, with a maximum opening distance of 45 cm (18").

Proper maintenance is essential for the long-term performance of the vent opener. All moving parts should be lubricated after installation, and occasional lubrication is recommended. When the window is not in use, such as during the winter months, the cylinder should be removed from the opener to prevent any accidental openings due to warm weather.

For added versatility, the automatic vent opener is available in four different models: - Automatic Single Spring Silver Aluminum Vent Opener - Automatic Single Spring Black Stainless Steel Vent Opener - Automatic Double Spring Black Stainless Steel Vent Opener - Automatic Double Spring Silver Aluminum Vent Opener - 132 Lbs Heavy Duty Automatic Vent Opener
