Description
The Honeywell MP909E1067 is a reliable, medium-force pneumatic damper actuator engineered for precise damper positioning in commercial HVAC air distribution and building automation systems. With a spring-return design, this actuator automatically returns to its fail-safe position upon loss of air pressure, ensuring dependable system protection and consistent performance.
Key Features
- Medium actuator force for dependable damper positioning across a wide range of HVAC applications
- 5–10 PSI spring range provides accurate, responsive control throughout the operating range
- 3″ stroke delivers ample travel for effective damper blade actuation
- Spring-return action ensures automatic fail-safe positioning on loss of control signal or air pressure
- 29 PSI maximum operating pressure for compatibility with standard pneumatic control systems
- 6.6 square inch diaphragm area for consistent force output and smooth actuation
- Dual barbed fitting accommodates both 5/32″ and 1/4″ OD tubing air connections for flexible installation
- Operating temperature range of -28°F to 160°F (-33°C to 71°C) suits a wide variety of indoor and outdoor mechanical room environments
