Smithsonian: National Air and Space Museum
Steven F. Udvar-Hazy Center
One of the fans at the Smithsonian’s Steven F. Udvar-Hazy Center failed catastrophically. To replace the failed fan, the client would have had to remove the side of the AHU and bring in a crane to lift the new fans into the unit.
Equipment Being Replaced:
Two large belt-driven plenum fans.
Array Type: IntelliCUBE XL
Tech Specs: 86,892 CFM, 6.31 TSP
Mainstream designed a modular fan array with components small enough to go through the existing doorway of the air handler. By utilizing Mainstream’s IntelliCUBE XL fan array, there was no need to use a crane to install the new fans. The old fans were removed and the new fans were installed over a weekend. An estimated $35,000 a year in energy savings will be realized because of the energy efficiency of the PMEC motors.
