Robertshaw motorized rectangular zone dampers

with parallel blades are perfect for low-pressure

zone control systems. Our rectangular zone

dampers are designed for light commercial and

residential applications with static pressure

systems not exceeding 1.2” WG.

Our rectangular zone dampers are constructed of

heavy gauge extruded aluminum. The parallel

blade dampers have fewer blades for silent

operation. The dampers feature an easy slip in

design and a simple 2-wire operation. These

dampers have been designed to provide long life,

silent operation, and require zero maintenance.

The new 3” wide blades move smoothly from open

to close with minimal friction and are operated by

a powerful 24V, spring return motor actuator.

The dampers come complete and ready for

installation. The motor and linkage are factory

assembled to the damper. All you need is to install

the damper and wire to the control panel.
