Fresh air system external exhaust port with check valve
Print Profile(1)
Description
Several improvements made based on the previous version
1. The valve opening and closing angle is larger, reaching about 80 degrees, whereas the previous version could only open within 30 degrees
2. The pipe length is increased to 52mm (excluding the rain cap part), which can adapt to more exhaust openings; the previous version was 32mm
3. Hinge data optimized for easier installation, providing extremely high freedom of swing after installation, improving exhaust efficiency
4. Air outlet flow optimized to improve exhaust efficiency
5. Still focusing on the best-looking exhaust, no magnets needed for installation, please support, thank you
Additionally, assembly now only requires a gentle push to install the valve; even women can do it themselves.
