Honeywell MP909D1227 Pneumatic damper Actuator 5-10 PSI 2.4" Stroke

The Honeywell MP909D1227 is a pneumatic damper actuator that can precisely control airflow in various HVAC systems. This small equipment opens and closes dampers in air handling units, variable volume terminal units, and small dampers by using pressurized air 5–10 psi to move a lever through a 2.4-inch stroke. Its low-friction bearings and sturdy aluminum body guarantee a dependable, seamless operation. When air pressure is off, the MP909D1227's spring-return feature automatically sets the damper to a pre-set value, ensuring fail-safe functioning in an emergency. It can be installed and maintained easily in a variety of configurations thanks to its flexible mounting options and leak-proof seals. By providing accurate airflow control, this actuator improves the efficiency of HVAC systems and results in better temperature regulation, lower energy usage, and quieter operation.
