2 Nm Damper Actuators – RA2 Series

Description

The RA2 series 2 Nm non-spring return damper actuators are designed for a variety of motorized damper control applications in ventilation systems. These actuators are ideal for use in Building Automation Systems (BAS), Building Management Systems (BMS), and Heating, Ventilation, and Air Conditioning (HVAC) environments.

They are suitable for controlling dampers, air handlers, economizer units, VAV terminal units, fan coil units, fan shutters, and unit ventilators. These actuators are direct-mounted on standard damper shafts and can regulate dampers up to approximately 0.5 m².
