HVLS fans for HVAC applications

Invented by MacroAir Technologies LLC in the USA this cutting edge fan technology behind the MegaFan product combines the laws of physics with NASA inspired airfoil blade designs to achieve optimum energy efficiencies whilst moving large volumes of air with very little air turbulence. With the MegaFan a gentle non-disruptive breeze is consistently generated to deliver a pleasing and comfortable environment.

The MegaFan can be used in place of HVAC equipment in many cases and the MegaFan technology is referred to as 'High Volume Low Speed' (HVLS) fan systems. This technology uses the concept of highly efficient extended airfoil blades that circulate a large column of air at just the right speed required to optimize the "cooling effect". The specially designed airfoil blade is quiet and extremely efficient it produces minimal air disruption directly below the fan. It is very effective in large commercial and industrial facilities where employee comfort is the primary goal.

The MegaFan can help cool, de-stratify layered air, warm whilst saving energy by better control of a building's temperature profile. The MegaFan system comprises 6 or 10 blades with a fan diameter from 8 to 24 feet, a 0.75kW or 1.5kW motor and gearbox plus the variable speed drive mounted in an enclosure. Our experienced engineers are able to install and commission the system to your requirements.

When replacing up to 25 standard industrial fans in a large facility, High Volume Low Speed fan systems can provide all the breeze necessary for an evaporative cooling effect of six to eight degrees, resulting in a more comfortable work environment and increased productivity.
 
Throughout the year, High Volume Low Speed fans can be used alone or in tandem with A/C or heating systems. When used with A/C systems, the fans distribute the air and allow thermostats to be kept on a higher temperature setting, producing less A/C output and significant energy savings. During heating seasons, the fans improve comfort by bringing trapped warm air from the ceiling down to floor level. Temperature differences of 15 degrees or more from floor to ceiling are common in the absence of the fans. With the destratification of heated air in a facility, thermostats can be kept at a lower temperature setting, producing less heat output and significant energy savings (20% and greater).
 
The fan's massive air mixing also results in greater absorption and dispersion of noxious fumes and damaging moisture and humidity, resulting in a healthier, drier, and safer environment. Other benefits include elimination of birds and bugs, as well as avoiding the noise and disruption that would be present if other air flow solutions were in place. Periodic maintenance of the High Volume Low Speed fans involves cleaning of the anodized blades, minor lubrication of components, limited bolt tightening, and inspection of built-in safety features.

Because of the large diameter of an HVLS MegaFan and the resultant column of air size these fans produce a unique and effective deep wall of horizontal moving air. This is called a horizontal floor jet. A floor jet is relative to a fans diameter and to a lesser degree the speed the fan is turning. Once the floor jet reaches it potential it migrates outward and radiantly until it meets a side wall or other large barrier; there it continues to entrain and circulate. This is what makes HVLS fans so effective. Small high speed fans regardless of their number cannot produce a similar floor jet of moving air. For example; and 8 FT fan would produce a floor jet of air approximately 1 metre deep. A 24 FT fan would produce a floor jet of air 2.8 metres deep.
 
MegaFans require very little maintenance. Both the motor and the gearbox (which is lubricated for life) have a 3 year. And all other components have a lifetime warranty.
