Siemens Building Technology 331-2988 Actuator
The Siemens 331-2988 No. 6 Pneumatic Damper Actuator is a heavy-duty, rolling diaphragm drive engineered for gradual or positive control of large dampers, centrifugal refrigeration inlet vanes, and multi-section air handling units. This high-temperature pneumatic actuator features an 8 to 13 psi nominal spring range and a 4-inch stroke, providing the mechanical force necessary for large-scale HVAC automation. Utilizing an ozone-resistant silicone rubber diaphragm and an all-metal body, this spring return damper actuator is built for longevity in demanding mechanical rooms. The integrated pivot mounting configuration, designed specifically for extended shaft or frame mounting, ensures flexible installation for technicians managing commercial HVAC systems. With 17.9 square inches of effective diaphragm area, the Siemens 331-2988 delivers reliable thrust for sequencing with other control devices or operating in high-ambient environments.
Key Benefits- Heavy-Duty Construction: All-metal housing provides superior durability in industrial and commercial HVAC environments.
- Precise Control: The 8-13 psi spring range allows for accurate sequencing and reliable fail-safe spring return operation.
- High-Temperature Resilience: Equipped with a specialized high-temp silicone diaphragm for reliable performance near heat-intensive equipment.
- Flexible Installation: Features integral pivot mounting and forward travel stops for customized stroke adjustment on extended shaft applications.
- Standardized Compatibility: Replaces common Powers Controls pneumatic drives and works seamlessly with standard 1/8" NPT air connections.
What is the maximum air pressure for this actuator?
The Siemens 331-2988 is rated for a maximum control signal pressure of 30 psi, ensuring compatibility with standard pneumatic control loops.
Can this actuator be used on fire and smoke dampers?
Yes, the No. 6 pneumatic actuator is often used for fire/smoke damper applications and is recognized for its high-force output in safety-critical air management.
Is the diaphragm replaceable?
Yes, the silicone rubber rolling diaphragm is a replaceable component, allowing for field maintenance without replacing the entire damper motor assembly.
