Johnson Controls D-3153-2 Damper Actuator

The Johnson Controls D-3153-2 Damper Actuator is a robust, 15-inch pneumatic piston positioning device engineered for high-demand HVACR and life safety applications. This multipurpose pneumatic damper actuator features a high-performance 8-13 psi spring range and a standard 3-inch stroke, delivering the reliable force required for smoke ventilating and proportional volume control. Built with a die cast aluminum body and a synthetic elastomer diaphragm, the D-3153-2 is designed for non-combustible durability. It includes a universal mounting bracket and a 2-way swivel head to ensure full power delivery even in non-parallel linkage configurations. Supporting a 0-20 psig control air pressure range, this unit is UL component recognized for use in dampers up to 16 square feet for proportional control or 25 square feet for two-position operation. The 1/8 inch NPT straight barbed fitting allows for seamless integration into existing terminal pneumatic systems.

Key Benefits

• High-Temperature Durability: Engineered for reliability in safety damper applications with all-metal bearings and a non-combustible aluminum housing.
• Flexible Installation: Features a telescoping linkage and swivel ball joint for fast, non-binding connection to damper shafts.
• Optimized Torque: Delivers significant positioning power (up to 158 lb-in at 20 psig) to ensure positive damper closure and precise modulation.
• System Compatibility: Universal bracket design simplifies field replacement for HVAC pneumatic actuators across various air handling systems.

Common Questions

What is the maximum damper size the D-3153-2 can operate?
For proportional volume control, it handles dampers up to 16 sq. ft. For two-position (on/off) operation, it can manage up to 25 sq. ft., provided torque requirements are met.

Can this actuator be used for smoke and fire dampers?
Yes, the D-3153-2 is UL recognized for use on UL 555/555S smoke and combination fire/smoke dampers with ratings up to 250°F.

How do I handle sequential operation or increased positioning power?
A pilot positioner should be added if you require precision sequential control or if the load requires more consistent positioning regardless of air pressure fluctuations.
