Johnson Controls D-3240 Pneumatic Piston Damper Actuator
Pneumatic Piston Damper Actuator
D-3240
The D-3240 Series Pneumatic Piston Actuators are multipurpose positioning devices designed for operating inlet vanes on centrifugal fans and compressors, in direct response to the output signal of a pneumatic controller. These actuators can also be used on other applications that require a large amount of positioning power from a single actuator, such as large damper applications, provided that the damper is designed to withstand the high torque capabilities of the actuator.
• all-aluminum housing which is lightweight and non-combustible
• swivel, single pedestal or duplex pedestal mounting options for flexible mounting configurations
