Io Hvac Controls RM-2210 Rectangular Zone Damper 22x10 in

Product Description

The IO HVAC CONTROLS RM-2210 is a rectangular zone damper designed for zoned HVAC distribution systems. It features a 35-second Belimo actuator with a 3-wire control configuration, allowing the damper blade to be driven open and closed by a zone control board or thermostat panel. At 22 inches wide by 10 inches tall, this damper is sized for medium-to-large trunk or branch duct runs. HVAC technicians install this unit as part of multi-zone residential or light commercial systems where individual areas require independent temperature control.

The RM-2210 is suited for rectangular duct zoning applications in forced-air systems. The integrated Belimo actuator eliminates the need for a separate motor assembly, streamlining installation in tight mechanical spaces. This damper is typically installed in main trunk lines or larger branch ducts serving zones that require proportional or on-off airflow control. It is commonly specified in new construction zoning projects and retrofits where duct dimensions match the 22 by 10 inch opening.

Key Features

• 22 x 10 inch rectangular damper sized for medium-to-large duct openings
• Integrated Belimo actuator with 35-second travel time for smooth, controlled blade movement
• 3-wire actuator wiring compatible with standard zone control boards
• Factory-mounted actuator reduces field assembly time
• Designed for on-off or open-close zone control in forced-air duct systems

Compatibility

Designed as an OEM-style rectangular zone damper for use with Rheem 22 x 10 duct applications and compatible with zone control systems that support 3-wire Belimo actuator wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handling unit and disconnect power to the zone control panel before beginning damper installation. The damper should be mounted in the duct with airflow direction matching the blade orientation marked on the unit body. Verify actuator wiring matches the zone board terminal designations before restoring power.
