Why Trust Airius?

Why should every building with ceilings above 20' have a destratification fan system, and why should Airius be the company that provides it?

Why Airius Fans Are Unique

Airius destratification fans will significantly reduce “hot spots” and “cold spots” as well as energy consumption and utility costs due to heating, ventilating, and air conditioning (HVAC) in any existing facility. Further, these “too hot”, “too cold,” and “too costly” problems can be substantially avoided in new facilities or major renovations of existing facilities when HVAC designers coordinate use of our Airius fans within their conventional HVAC designs. Our clients generally realize 20% – 30% or greater annual HVAC energy consumption reduction and cost savings that typically yield simple economic payback periods of 1-4 years for the purchase and installation costs.

Airius destratification fans uniquely achieve thermal air destratification because of their patented air turbine design with stator vanes and Venturi nozzles. With any fan, the spinning impeller blades induce a rotational component into the air flow from the fan causing turbulence and reduced vertical (ceiling to floor) throw distance. Airius’ patented stator vanes eliminate rotational air flows and create columnar laminar air flows. The effects of the Airius stator vanes and Venturi shaped nozzles are increased air flow velocities and significantly increased vertical (ceiling to floor) throw distances for any given fan power consumption. These increased velocities and throw distances enable Airius fans to efficiently and effectively throw relatively warm, buoyant air from ceiling to floor to thermally destratify conditioned spaces with ceilings up to 125’ above the floor. Other ‘destratification fans,’ that do not have stators and/or Venturi nozzles, can only efficiently destratify conditioned spaces with ~30’ or lower ceiling heights with any reasonably economically sized motors.

Airius fans can destratify conditioned spaces within their design ceiling heights because their vertical throw distances are greater than their design ceiling heights; i.e., Airius fans can throw relatively warm and buoyant air near ceilings vertically down towards floors through layers of cooler and denser air at distances that are greater than their design ceiling heights. These throw distances mean that there is sufficient air flow verlocity at the floor to have the air flows spread laterally across the floor before rising up to set-up the necessary thermal equalizing air circulation patterns in the area of influence of each fan. Air flows from a properly laid-out array of Airius fans will set up effective full-floor to ceiling air circulation patterns in the areas surrounding each fan to thoroughly mix and equalize humidity and temperature throughout the full ceiling-to-floor and wall-to-wall volume of a conditioned space.

Please also note that the relatively high velocities and tight columnar laminar air flows produced by Airius destratification fans induce surrounding air to entrain into the laminar air flow columns from our fans; so, the air volume (cubic feet per minute, or cfm) delivered to the floor is actually greater than the air volume (cfm) exiting the fan nozzle. Since this air volume is delivered to the floor at a velocity of about 110-130 feet per minute, the air delivered to the floor spreads radially across the floor from the 4’-20’ diameter floor impact area before it gently rises to again be drafted through the fan or to again be entrained in the air flow from the fan.

Airius fans are unique because they efficiently and effectively destratify conditioned spaces with ceiling heights from as little as 10’ up to as high as 125’ above floor level.
