The Blue Giant Eagle VI Series has an innovative blade design that moves more air with less energy. The six-airfoil system increases air velocity in summer and de-stratifies hot air pockets in winter, resulting in an energy cost reduction of up to 30%. In many cases a return on investment can be realized in less than two years. Eagle VI Series HVLS fans keep indoor temperatures at comfortable levels in warehouses, sporting facilities, open-concept offices, and other high-ceiling locations. Specifying an Eagle VI model for a new construction project can also reduce building costs by lowering required HVAC tonnage and duct work.
