When the mechanical engineering designers, FEA Consulting Engineers of Henderson, Nev., were deciding on the right airside system to keep the top-notch talent comfortable in the Las Vegas heat, they turned to Mechanical Products Nevada Inc. and to Fanwall Technology® by Huntair Inc.
FEA Consulting Engineers provides mechanical, electrical, plumbing, and low voltage engineering services. The firm provided the mechanical engineering design for the Joint and meeting rooms as well as the hotel’s North and Tower expansions, casino expansion, and pool expansion.

THE NEW JOINT
The Hard Rock Hotel & Casino is a premier destination entertainment resort located on one of Las Vegas’ fastest growing entertainment corridors. The original Joint concert venue opened in February of 1995.The Joint was the first rock ‘n’ roll venue in Las Vegas built at a high-end boutique property and has attracted top-notch performers.The new Joint essentially doubled its original capacity to accommodate an audience of 4,000, and includes VIP hospitality suites and the latest in video, sound, and lighting systems. The new Joint’s venue can serve a variety of purposes, from hosting concerts, wrestling, and boxing events to corporate or trade show events.
THE CHALLENGES
Low sound levels, reliability, and tight temperature control were high priorities to Vic A. Sibilla, P.E., COO and owner, FEA Consulting Engineers, in selecting the air conditioning system. Sibilla first learned of Fanwall Technology by Huntair during a local touring showcase of technologies with Cory Nehls, VP, Mechanical Products Nevada Inc.“I was so impressed when I first saw and heard the Fanwall® array running that I couldn’t wait to find the right application. Engineers tend to be very traditional when it comes to ‘new’ technology, but this equipment definitely made an impression,” Sibilla commented.

RELIABILITY AND LOW SOUND
A visit to Huntair’s factory in Portland, Ore., was arranged with a representative from the hotel’s engineering team, Sibilla and Nehls. Nehls commented, “We were all impressed with the quality of the Fanwall product at the factory, and had a chance to listen to a unit operating in the lab.”“The owner was drawn to the low sound and the low maintenance features of the Fanwall array, especially the fact that there were no belts to worry about or bearings to grease,” Sibilla added. He went on to say, “The Joint can’t tolerate any downtime or acoustical problems, especially during a performance, and the Fanwall direct drive fans were the best technology available to mitigate those risks.”
FAST-TRACK PROJECT
With an April opening set, the air handlers were needed in a very short time and Huntair provided a fast production cycle to keep the project on track. The job consisted of 14 Huntair air handlers: eight for the Joint concert area and six for the Joint meeting rooms. Air handlers ranged in size from 6,500 to 34,000 cfm.Sibilla summed up the project by saying, “The owner is so impressed at how quiet these units operate that he wishes he could change out all of his fans at the hotel to a Fanwall array.”
The Application at a Glance
• The Joint is a state-of-the-art concert venue seating up to 4,000 at the Hard Rock Hotel & Casino, Las Vegas.• Eight air handlers powered by Huntair Fanwall Technology supply 142,500 cfm of conditioned air to the concert facility.
• Six air handlers powered by Huntair Fanwall Technology supply 104,000 cfm of conditioned air to the meeting rooms.
• Supply and return fans inside air handlers are designed using multiple fan arrays to provide a reliable and low sound air supply.
• Multiple fan arrays consist of two to six fans providing reliability through redundancy. Redundant variable frequency drives for both supply and return fans ensure reliability and are used to vary airflow.
