Assurance that MacroAir HVLS fans perform to spec
When you spec AMCA-certified products into your HVAC and building designs, you’re assured of validated product performance ratings based on standard test methods and procedures.
Air movement products, such as HVLS fans, can carry AMCA performance seals only after ratings have been submitted to and approved by AMCA’s staff. In addition, each certified product line is subject to continuing check tests every three years.
AMCA Certified Performance Ratings are your way of comparing HVLS fan performance ratings among manufacturers.
MacroAir Airvolution 8, 10, and 12-foot HVLS fans have been certified by AMCA for fan performance and are the only HVLS fans that have carry the AMCA certification.
The AMCA-approved method of measuring the performance of HVLS fans is to measure the “thrust,” which is the force the fan produces as a result of the air being pushed through it. The higher the thrust value of an HVLS fan, the higher the volume of air or performance. A formula can be used to convert from thrust to CFM, but the results are only certifiable for 8 feet and below. Thrust values are used to certify fans above 8 feet.
Why don’t we certify our fans above 12-feet in diameter? AMCA doesn’t have a facility large enough!
