Johnson Controls D-3153-20 Damper Actuator

For versatile pneumatic control of ventilation and safety dampers, the Johnson Controls D-3153-20 Damper Actuator provides a rugged, field-ready solution. Engineered with a large 15-inch synthetic elastomer diaphragm and a durable die-cast aluminum body, this linear actuator is built for high-demand environments. It features a 3-inch stroke and a nominal 8-13 psi spring range, ensuring consistent displacement in both proportional and two-position applications. This model is capable of driving dampers up to 16 square feet for proportional volume control and up to 25 square feet for two-position actuation. The D-3153-20 includes a built-in auxiliary mounting bracket and a 1/8-inch NPT straight barbed fitting air connection for simplified integration. A 2-way swivel head and telescoping linkage ensure non-binding movement and full power delivery across the entire range of motion, maintaining precise HVAC damper control even under varying load conditions.

• Flexible Installation: Comes with a swivel ball joint connector and telescoping linkage for fast, adaptable mounting.
• Reliable Operation: Utilizing a high-quality pneumatic piston actuator design proven in over a million installations.
• Wide Operating Temperature: Performs reliably in ambient conditions ranging from -20°F to 150°F (-29°C to 66°C).

Common Questions

Is this actuator suitable for fire and smoke dampers?
While the D-3153 series includes models recognized for fire/smoke applications, the D-3153-20 specific configuration is typically used for standard ventilation control. Always verify local codes and the specific UL rating on the nameplate for safety-critical applications.

What air pressure is required for operation?
The standard control air pressure for normal HVAC operation is 0–20 psig. For safety functions or higher torque requirements, it can support a maximum control pressure of 30 psig.

Can I repair the internal diaphragm?
Field repairs are not recommended by the manufacturer. If the actuator fails to hold pressure or reach its 3-inch stroke, the entire unit should be replaced to ensure system reliability.
