Powerfoil X2.0 from The Big Ass Fan Co. features a patented new airfoil system that increases overall coverage by 28 percent to improve a natatorium’s IAQ by sweeping the chloramines off the water’s surface and aiding ventilation. In the summer, it keeps spectators and athletes comfortable without creating a chilling effect, while creating uniform temperatures in the winter months to lessen the load on heating systems, per maker.
