Description
The Honeywell MP909D1367 is a pneumatic spring return damper actuator engineered for reliable, precise damper positioning in commercial and industrial HVAC systems. Designed to respond to pneumatic control signals, this actuator delivers consistent performance across a wide range of building automation and air-handling applications.
Key Features
- Spring return operation ensures fail-safe damper positioning upon loss of air pressure
- 3 square inch diaphragm for effective force generation and responsive actuation
- 5–10 PSI spring range for accurate modulating control
- Barb fitting designed for 3/32″ OD tubing air connection for easy pneumatic hookup
- 3″ stroke provides ample travel for a wide variety of damper linkage configurations
- 3/8″ threaded shaft for secure and straightforward mechanical connection
- Operating temperature range of 50–140°F (10–60°C) suits most mechanical room and air-handling unit environments
- Humidity range of 5–95% RH (non-condensing) for broad environmental compatibility
