MacroAir HVLS Fans

Collectors & Filters sells and support MacroAir to bring their HVLS fan systems to facilities throughout Indiana and the Midwest. We help you select the right fan for your space, provide layout assistance, and connect you with the support you need.

MacroAir invented HVLS technology in 1998 and has refined it ever since. Unlike standard high-speed fans that create chaotic turbulence, their blade design and direct-drive motors deliver efficiency with only two moving parts. You get whisper-quiet operation at 53 dB and annual energy savings which vary by facility size and usage.

The MacroAir Advantage

Two moving parts. That’s it. MacroAir’s direct-drive architecture eliminates the gearbox entirely: no oil changes, no bearing replacements, no scheduled downtime. The result is a 50,000-hour warranty (that’s 28 years of continuous operation).  Less moving parts means reduces friction, maintenance, and noise.

Key Specifications & Benefits

  • Coverage Area up to 20,000 sq ft: A single fan creates a massive vertical air column that pushes stratified ceiling air downward and outward. One fan replaces dozens of high-speed units.
  • 33-61 dB Sound Level (depending on size and model): Library-quiet operation at maximum speed. Traditional gear-driven fans, small high-velocity, run at higher dB sounds (generally between 50-60). Your team can hold conversations.
  • AirBrain Processor with Adaptive Voltage Control: MacroAir’s patented AirBrain compensates for fluctuations across 100-480V input without a separate VFD. That’s $2,000 to $5,000 in control components you don’t need to buy.
  • Anodized Aluminum NASA Airfoil Blades: Extruded and clearcoat-finished for corrosion resistance. Built for warehouses, agricultural facilities, and outdoor washdown environments.

Why Choose MacroAir?

Reliability matters. Whether you are running a pharmaceutical warehouse or a dairy barn, you need equipment that meets your needs and thermal comfort standards.
