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.

Frequently Asked Questions — MacroAir HVLS Fans

What is an HVLS fan and how does it work?

MacroAir HVLS fans use large-diameter blades spinning at low RPM to move massive volumes of air gently and efficiently. A single fan generates a wide vertical air column that pushes stratified warm air down from the ceiling and circulates it outward across the floor. This creates a consistent temperature throughout the facility without the turbulence or noise of traditional high-speed fans. See how HVLS fans fit into a complete industrial ventilation system.

Who invented HVLS fan technology?

MacroAir invented HVLS fan technology in 1998. They have refined the design ever since and continue to manufacture their fans in Colton, California. As the originator of the category, MacroAir holds multiple patents covering blade geometry, motor architecture, and control systems. We also supply Hunter Industrial HVLS fans if you want to compare options.

How much square footage can one MacroAir fan cover?

A single MacroAir fan can cover up to 22,000 square feet depending on the model and ceiling height. Their largest 24-foot diameter fans in the AVDX series are engineered to replace dozens of standard high-speed pedestal or ceiling fans. Proper layout and fan selection are critical to achieving full coverage. Contact us with your building dimensions and we will size it for you.

What sizes do MacroAir fans come in?

MacroAir fans are available in diameters from 8 feet to 24 feet across the AVDX series. This range covers small machine shops, large distribution warehouses, agricultural buildings, and everything in between. Collectors & Filters can help you determine the right size for your ceiling height, layout, and occupancy type. We serve Indiana manufacturers and surrounding states.

How loud are MacroAir HVLS fans?

MacroAir fans operate between 50 and 53 dBA at full speed, comparable to a quiet library. Employees can hold normal conversations directly beneath the fan. Traditional gear-driven fans and small high-velocity units typically run louder, making MacroAir a strong choice for facilities where communication, focus, or noise compliance matters. This pairs well with dust collection systems that also need to keep shop noise manageable.

Do MacroAir fans require a separate variable frequency drive?

No. MacroAir fans include the patented AirBrain processor with Adaptive Voltage Control built into the unit. This automatically compensates for voltage fluctuations across a 100 to 480 volt input range, eliminating the need for a separate VFD. Depending on your facility, that can represent $2,000 to $5,000 in control components you will not need to purchase, install, or maintain.

How many moving parts does a MacroAir fan have?

Two. MacroAir uses a direct-drive PMAC motor that eliminates the gearbox found in traditional HVLS fans. No gearbox means no oil changes, no bearing replacements, and no scheduled downtime for drivetrain maintenance. This is the primary reason MacroAir backs their fans with a 50,000-hour warranty, roughly 28 years of continuous operation. For comparison, our maintenance guide shows what routine upkeep looks like on dust collection equipment with more moving parts.

What is the MacroAir warranty?

MacroAir provides a 50,000-hour warranty on their direct-drive motor systems. At continuous operation, that equals approximately 28 years. This warranty is made possible by the two-moving-part design, which removes the gearbox as the primary failure point in conventional fan systems. See the full MacroAir product page for details.

Can MacroAir fans integrate with a building automation system?

Yes. MacroAir fans support native BACnet and LonWorks communication protocols. This allows direct integration without additional gateways or proprietary adapters. Facilities with existing BMS infrastructure can add MacroAir fans without modifying their control architecture. This also makes it straightforward to coordinate fan operation with industrial ventilation systems running in the same facility.

How do I get help selecting the right MacroAir fan for my facility?

Collectors & Filters handles fan selection, layout planning, and system design for Indiana manufacturers and facilities in Northern Kentucky and Southern Michigan. We work through the technical calculations to make sure you get the right fan count, diameter, and placement for your building. Call 317-910-1497 or use the contact form to get started.
