Engineering solution
What this equipment is designed to solve
Leaf (butterfly) type check valves to prevent reverse air flow in ventilation systems. When the fan is running, the petals open under air pressure, and when stopped, they close under their own weight.
Application
Suitable applications
- Preventing backdraft when the fan is off
- Protection against cold air penetration
- Separation of ventilation zones
- Exhaust systems with multiple fans
