WHY ACOUSTIFLO?

• 15% more efficient than traditional fans

• Enhanced flow path for optimum efficiency

• Proven Twin Cities fan with enhancements

• AMCA certified for sound and performance

• 10-12 dB sound power quieter than conventional plenum fans in the first 4 octave bands

• Airflow monitoring of each fan

• Direct drive- no belts, sheaves or fan bearings

• AcoustiFLO fans can be installed inside Haakon units for new construction

The AcoustiFlo Secret to Reduced Low Frequency Sound

An Engineered Flow Path

Minimizes turbulence (the diffusers)

o Less turbulence = less low frequency noise

Maximize sound absorption

o (12 inches of acoustic fill)

o 10 to 20 dB quieter in critical bands

The AcoustiFlo Acoustic Platform

Requires no additional air tunnel length

Improves fan performance

It is no small task for a larger diameter wheel to deliver small wheel acoustics in a reduced length air tunnel. US Patents 7,001,140 and 7,357,621

AcoustiFLO has provided technologically advanced fan assemblies for the semi-conductor industry, high-rise office buildings, hospitals and educational facilities world-wide for over 20 years.AcoustiFLO began in the 90’s offering the most aerodynamic and acoustically efficient axivane fan towers available to the worlds

top tier semi-conductor manufacturers. Utilizing our in-house engineering capabilities, this same technology was applied to office buildings and high tech facilities in multiple cities and sites across the U.S.

Adjusting to changes in the manufacture of semiconductors and in HVAC system design, in early 2004 AcoustiFLO developed it’s patented modular fan system, the 686q. The 686q offers a blend of the high efficiency of larger fans combined with the modular flexibility and acoustic advantages of smaller multiple fans.

Who is AcoustiFLO?

Our company headquarters and manufacturing facility is located in Boulder, Colorado. We serve customers throughout the U.S. and world-wide.


All AcoustiFLO products are AMCA certified for efficiency and acoustics and are used extensively on many projects requiring LEED certification.

● Engineered Flow Path

● 100% Acoustic Cotton fill ●12” Outer Diffuser ●6” Inner Diffuser

● Optional Inlet silencer for critical applications

● Fully integrated internal spring isolation in each module eliminates flex connections

Our products are applied in factory-built, custom air handlers and field erected air-handling systems.

No Ordinary Plenum Fan.AcoustiFLO is the performance-engineered, specific purpose plenum fan — designed to be the quietest, most compact, modular, energy-efficient fan you’ll ever meet.


AcoustiFLO’s efficiency cannot be matched.

Flexibility in blade count and wheel width combined with infinitely variable speed provides a spectrum of typical HVAC pressure and flow requirements at maximum efficiency.

Every fan company will tell you their fans are quiet and efficient. The question is — can they actually back up their claims? At AcoustiFLO we back up the efficiency claims we make with industry recognized, published, third-party verification.

Utilizing a variable speed motor (VFD) and myriad wheel geometries, AcoustiFLO obtains multiple flows and pressures with identical efficiency — up to 12” of pressure within the industry motor speed limit of 90hz. By changing three variables: fan quantity, type and speed, AcoustiFLO addresses a broad spectrum of high performance AHU applications.

● 10% + higher peak static efficiency than competing plenum fan arrays (AMCA Certified)

● Higher fan efficiency = reduced load on refrigeration plant

● Up to 12” of pressure below 90hz

● Motor efficiency up to 94.1% (NEMA Premium)

● Optional exit guide vanes for max. efficiency

● Direct drive only to eliminate drive train losses

In addition to superior acoustics and efficiency, AcoustiFLO’s flexibility and broad capacity range offer improved system reliability combined with 100% n-1 redundancy in many applications by applying the proper number of fans in an array.

AcoustiFLO Efficiency

Two 10hp fans with a 14% difference in energy efficiency are NOT equal


AcoustiFLO addresses the issue of fan noise much differently than other plenum fans.Regular plenum fans discharge air radially, slamming it into the walls of the fan box or air handler, creating turbulence and generating noise.

We engineered (and patented) a curved and acoustically attenuated flow path using a slotted aluminum diffuser to minimize turbulence by gently seducing the air around the curve, under control — substantially reducing regenerated noise.

For applications where inlet noise reduction is critical: We offer an optional inlet silencer that adds only 19” inches in direction of air flow, making AcoustiFLO 10 to 20 dB quieter in critical octave bands.

AcoustiFLO is uniquely AMCA certified for sound with all accessories.

AcoustiFLO Acoustics

Our patented flow path results in an acoustic spectrum that is remarkably different from ordinary plenum fans or arrays.
