Johnson Controls D-3153-3 Damper Actuator

The Johnson Controls D-3153-3 Damper Actuator is a heavy-duty pneumatic damper actuator designed for reliable proportional or two-position control in commercial HVAC systems. This pneumatic piston actuator features a 5-10 psi spring range and a generous 3-inch stroke, making it a standard choice for technicians managing ventilating dampers and smoke control systems. Constructed with a die-cast aluminum body and a rugged 15-inch synthetic elastomer diaphragm, the D-3153-3 provides consistent force and long-term durability in demanding environments. The unit includes a 1/8-inch NPT straight barbed fitting for easy integration into existing pneumatic lines using 5/32 or 1/4-inch O.D. polytubing. Engineers and contractors value this model for its universal mounting bracket and telescoping linkage, which simplify field installation and ensure compatibility with a wide variety of damper configurations up to 25 square feet. Operating effectively within a 0-20 psig control air pressure range, this Johnson Controls pneumatic actuator is built for precise air volume regulation and safety damper functions.

• Universal Compatibility: Includes a versatile mounting bracket and telescoping piston rod to facilitate fast installation on various damper brands.
• Rugged Construction: The all-aluminum housing provides a lightweight, non-combustible solution suitable for high-temperature safety applications up to 250°F.
• High Torque Output: Delivering significant power at 20 psig, this actuator is capable of managing proportional control for dampers up to 16 square feet.
• Field Flexibility: Features a 2-way swivel head for non-binding movement and a 1/8" NPT air connection for standard pneumatic fittings.

Common Questions
