- This blind window opener automatically opens and closes based on ambient temperature changes. Starting to open at 17-25°C (63-78°F) and reaching full open at 30-32°C (86-90°F), it provides passive ventilation without electricity or batteries, ideal for greenhouses, sunrooms, and skylights.
- Constructed from quality aluminium alloy, this automatic window opener resists rust, ensuring long-lasting performance in various weather conditions. The robust materials withstand daily use while maintaining smooth operation throughout the seasons.
- Equipped with a powerful internal spring and support bar system, this window opener provides additional protection against sudden gusts. The 15kg closing force ensures the window closes securely when temperatures drop, preventing wind damage to your blind windows and frames.
