MacroAir Technologies
 • Moving air breaks up the moisture-saturated boundary layer surrounding the body, accelerating evaporation to produce a cooling effect
• During heating seasons, Airvolution HVLS technology de-stratifies uneven temperatures that occur at each level throughout the facility – forcing unused heated air from the ceiling down to floor where it can have a positive impact on employees. This heat differential can be in excess of 15°F from ceiling to floor, enabling significant cost savings when thermostat levels are reduced
• One Airvolution fan consumes about the same electricity as one high-speed alley fan while moving over 12 times the amount the air
• One Airvolution fan costs about a nickel an hour to operate
• Cows do not bunch up - air moves over the herd, regardless of their position in the barn
• Flying insects stay away, or on the ground. Birds also react to the large, slow moving air foil blades and stay out!
• Quiet and non-disruptive operation       1.866.MOVE AIR                http://www.macro-air.com
