Description
The Siemens Combustion SQM41.254R11 Modulating Damper Actuator is a better part for controlling the airflow in an HVAC system because it has a 90 lb-in torque. It controls the damper positions proportionally, depending on the control signals received. The 110V power input turns the actuator and controls the flow of air or gas through a 3/8” connection to maintain combustion conditions. It is widely used in industrial burners and commercial HVAC system units to improve energy efficiency and the safety of the systems. The layout is compact, providing a low-voltage output, no energy consumption during stand by, durable material for a long service span and is suitable for meeting high requirments for air regulation.
