• Improves comfort by eliminating over-cooling and overheating
• Saves energy by automatically directing over-conditioned air flow to areas still needing the conditioned air
• Saves energy by reducing air flow to spaces that are not being used
• Under-sized damper slips easily into diffuser collar, between flexduct drop and ceiling diffuser

The QSR24 is a second generation power close, spring open actuator that provides increased torque and quiet operation. An internal brake controls the rewind speed of the motor and eliminates the loud noise caused by the motor and gears when rewinding.

The A250-MOC is a 24VAC power open/dose or modulating actuator for use with zoning dampers and provides 250 in-oz of torque. The actuator can operate either open/dose or modulating.

Used with the eWD2 and eWD3 panels, the A250-MOC can be used for bypass excess air flow by opening just enough to maintain the minimum air flow and eliminate the need for bypass ducts and a barometric damper.

The A250-MOCT is supplied with mounting tabs and mechanically attached to the damper on standoffs.

The A80-MOC is a 24 VAC power open/close or modulating actuator for use with zoning dampers. Tested to over 9 million cycles, the actuator is quiet and reliable.
