Johnson Controls D-3244-5100 Pneumatic Piston Damper Actuator with Pilot Positioner

The Johnson Controls D-3244-5100 is a pneumatic piston damper actuator from the D-3240 Series, designed for precise control of HVAC dampers and inlet vanes. This unit features an 8 to 13 psig spring range and comes factory-equipped with a D-9502-5 pilot positioner for enhanced positioning accuracy and dynamic stabilization.

Key Features:

• 8 to 13 psig (56 to 91 kPa) operating spring range
• Factory-installed D-9502-5 pilot positioner for precise damper positioning
• 4-inch stroke length for reliable operation
• Includes swivel mount bracket, clevis, and crank arm
• Barb fittings for 5/32 inch or 1/4 inch OD poly tubing
• Maximum control air pressure: 25 psi

Applications:

• VAV (Variable Air Volume) control dampers
• Inlet vane control on centrifugal fans and compressors
• Large damper applications requiring high positioning power
• Applications requiring dynamic stabilization and sequential control

The integrated pilot positioner provides precision relay control to adjust and maintain the actuator in exact positions, making this ideal for applications demanding precise damper positioning. The D-3240 Series actuators are multipurpose positioning devices that respond directly to output signals from pneumatic controllers.
