MacroAir is known for its large industrial fans that provide a comfortable working environment for warehouse employees. It has some of these units, including a 16-foot model, on display at ProMat.

In addition, MacroAir is highlighting a trade-up program that allows users of any large fans to move up to the latest MacroAir technology. The company says there are more than 100,000 fans installed in the market today. Many of them rely on inefficient gear boxes instead of today's direct-drive technologies. MacroAir will do a free analysis to determine optimal air flow for a facility.
