Round Remote Balancing Damper

Application and Design

Model RBDR-50 is a round remote powered balancing damper designed to regulate the ﬂow of air in a HVAC system. This balancing damper is ideal for applications where it is difﬁcult to get access to manually adjust the dampers and balance the airﬂow. The ‘EZ Balance’ hand held remote (equipped with 9 volt power supply) operates the damper actuator when connected to the diffuser connector or wall/ceiling plate
