When Selecting HVLS Fans, 'Seeing' Helps Believing

Nov. 1, 2013
AirViz is a 3D motion tool based on advanced fluid dynamics modeling and is tailored to the specifics of MacroAir fans.

Well, now, you can "see" airflow in action — as in the airflow of a MacroAir high-volume/low speed (HVLS) fan — thanks to AirViz, MacroAir's new computational fluid dynamics modeling tool.

The tool gives customers an opportunity to visualize the potential performance and cost-saving prospects of the company's products within a dedicated space.

MacroAir sources say it's a helpful way for customers to "try before they buy."

AirViz is tailored to the specifics of MacroAir fans. Using specifications from a potential installation space, the tool can produce a 3D motion video that predicts the airflow, temperatures and cooling/heating effects from a MacroAir HVLS fan, represented by colored visual elements.

“Through the virtual performance simulation produced by AirViz, we are able to test multiple MacroAir fans throughout a facility to find the best air movement solution for the space, and then demonstrate this to the customer” says MacroAir Engineering Manager Michael Danielsson. “We’ve adapted the latest fluid dynamic technology to replicate the performance of each of our fans by comparing the simulations with live wind speed testing. By tracking air movement we are able to provide a solution for our clients that not only will solve their need for comfort and air movement, but also save money.”

According to the company, MacroAir HVLS fans are a proven solution for changing perceptible room temperature by 5 to 15 degrees, and lower heating and cooling costs by as much as 20% when used in conjunction with traditional HVAC equipment.

AirViz will allow companies to be even more efficient with the ability to spec and test fan locations for optimum airflow, resulting in energy savings.

“We engineer air, having originated HVLS technology and continuing to perfect it to provide our end users with the most advanced air movement solutions that also deliver results,” said Eddie Boyd, president of MacroAir. “AirViz is the next generation product specification tool that can be used to support purchase decisions and increase consumer confidence in our industry.”

MacroAir's AirElite has a powerful 1/2 horsepower motor, onboard electronics and fully integrated control system, all combined within a streamlined power unit and elegant frame.

MacroAir manufactures five lines of HVLS fans in diameters from 6- to 24-feet, that feature six airfoil blades utilizing NASA-engineered wing design and the company’s patented 6ixBlade™ technology. The company’s products are covered by a 12-year limited warranty on all parts with the exception of the blades, hub and frame, which carry a lifetime warranty.
