Proportional Damper Motor

Precision Airflow Control for Modern HVAC Systems

Havkon’s PM Series Damper Actuators are engineered for precise proportional control of air dampers in ventilation and air-conditioning systems. Designed for seamless integration into building automation systems (BAS), the PM Series ensures efficient modulation of airflow to match varying thermal demands across diverse environments.

Operating exclusively on 24 V AC/DC, each actuator supports proportional input signals of 0–10 V, 2–10 V, or optionally 0(4)–20 mA, with matching voltage or current-based position feedback output. These actuators deliver smooth and responsive control, making them ideal for advanced HVAC zones requiring continuous modulation.

The PM Series is available in torque models of 2 Nm, 5 Nm, 10 Nm, 15 Nm, and 30 Nm—covering a wide range of damper sizes and system specifications. Built with high-efficiency motors and reinforced mechanical design, each unit offers quiet operation, energy efficiency, and long-term durability.

Additional features include adjustable rotation angle, manual override capability, overload protection, and easy direct mounting onto round or square shafts. With their compact form factor and tool-free installation, PM actuators provide flexibility for both retrofit and new installations in energy-efficient HVAC infrastructures.
