Honeywell MP909E1059 Pneumatic Damper Actuator Medium Force 2.75" Stroke

The Honeywell MP909E1059 is a medium-force pneumatic damper actuator designed for controlling HVAC dampers in commercial and industrial applications. This spring-return actuator operates on 5-10 PSI air pressure and provides reliable, proportional control of damper positioning.

Key Features:

• 2.75-inch stroke length for precise damper control
• 5-10 PSI operating pressure range for proportional control
• Medium force output suitable for standard commercial dampers
• Spring return design for fail-safe operation
• 6.6-inch overall height for compact installation
• Direct-coupled mounting for easy installation
• Durable construction for long-term reliability

This actuator is ideal for VAV boxes, mixed air dampers, and other HVAC applications requiring precise pneumatic control. The spring-return mechanism ensures the damper returns to a safe position in the event of air pressure loss, making it suitable for life-safety and critical control applications.
