Efficiency
It is common knowledge in fan design that the power required to drive a fan varies approximately with the cube of the average air speed through the fan – i.e. doubling the air speed requires eight times the power. Accordingly, a fan delivering air at 20 mph requires 64 times as much power as one delivering air at 5 mph.
With their larger diameters and Rotatair™ blades, AirMotion Sciences AltAir™ HVLS fans create larger flows of air that have proportionally less surface area and therefore encounter less friction and related drag. This allows the air to move further using less energy and effort than smaller fans. Combine this with judicious use of our VPT™ (Variable Pitch Technology) and you get what we call optimal CFM – Complete Facility Movement of air.
This energy efficiency equates to energy savings where one AirMotion HVLS fan does the work of, and replaces, many typical high-speed industrial fans and other HVAC solutions, for example:
Efficiency = Savings versus using 36” Fans – It is estimated that it would take at least 15 high velocity ½+ hp 36” fans (or twelve 48” fans) to accomplish the same cooling effect of one 15’ 1 hp AirMotion HVLS fan per 10,000 square feet of a typical 100,000 square foot DC facility in Oklahoma City. The annual electrical operating costs over six months of those 15 smaller fans would be approximately $2,376, versus $302 for the one AltAir fan. The difference in installed cost of the 15 smaller fans is estimated to be $1000 less than the installed cost of one AltAir fan.
Accordingly, payback of the cost difference is less than a year ($2,074 annual savings versus incremental installation cost of $1000). Full payback on the installed cost of one AirMotion AltAir HVLS fan as a cooling alternative is less than 3 years. The NPV (Net Present Value) over 10 years would be about $15,000 per AirMotion HVLS fan (not to mention that the smaller fans will most likely require frequent maintenance and replacement). Cooling 100,000 square feet of DC space means big savings with the big fans. In addition, the AirMotion HVLS fans provide more effective evaporative cooling that results in greater employee comfort and productivity.
Efficiency = Savings versus other HVAC equipment – As above, significant financial benefits can result from using AirMotion HVLS fans in lieu of, or as a supplement to, installing and operating typical heating, ventilating, cooling, and other air movement equipment. For example, AltAir fans are more effective in performance and cost than multiple wall and ceiling mounted ventilation fans that typically have eight to twenty-five horsepower motors. Payback comes quickly from the operating cost savings while providing superior air movement.
AirMotion AltAir HVLS fans are efficient. This results in meaningful cost benefits. In addition, their effectiveness results in substantial Energy Savings.
