This item is an MCC Powers (acquired by Siemens) Model 331-2794 No 6 Pneumatic Damper Actuator. It is identical to the Siemens 331-2794.
It is surplus but new. As you can see from the photographs it appears completely unused.
The POWERS Controls No. 6 Pneumatic Damper Actuator is a heavy-duty, rolling diaphragm, spring return actuator designed to drive large dampers, centrifugal refrigeration inlet vanes, and other applications requiring a large, effective diaphragm area and long stroke. The 331-2794 has a nominal spring range of 3-13 psi (21-90 kPa).
Replaceable ozone-resistant, silicone rubber, rolling diaphragm
Pivot mounting for extended shaft or frame mounting
Positioning relay (optional)
Adjustable forward travel stops (optional)
Three spring ranges for sequencing with other control devices
The No. 6 Pneumatic Damper Actuator controls outdoor, return air, exhaust, face and bypass, and fan discharge dampers. It is recommended for heavy-duty applications using multi-section dampers where either unison or sequence operation is required.
This item retails for $149.99.
