Description
The Johnson Controls RCG08PRNC is an 8-inch round control damper engineered for dependable pneumatic airflow regulation in commercial HVAC systems. Featuring a normally closed (NC) fail-safe position, this damper automatically closes when pneumatic pressure is removed, making it ideal for applications where shutting off airflow on loss of signal is required for safety or energy efficiency.
Key Features
- 8-inch round duct diameter for straightforward installation into standard round ductwork
- Normally Closed (NC) configuration — damper closes on loss of pneumatic signal
- Spring range of 8 PSI to 13 PSI for precise pneumatic actuator control
- Galvanized steel construction for durability and corrosion resistance
