CLOUDWAY S10 Next-Gen EC Motor Features a cutting-edge Electronically Commutated (EC) motor that is digitally controlled using precise electronic pulses. This PWM technology enables the fan to operate quieter and control the full range of its speed 0 to 100% without generating great volumes of heat or noise. EC motors pay for themselves in the long run having twice the lifespan and being 40% more energy-efficient than AC motors.|Efficient Performance This attic fan has a 50,000-hour continuous run lifespan, using dual ball bearings that allow omnidirectional mounting. It is also IP-44 rated to resist dust and moisture while performing in most humid environments. The insulated damper uses gravity-fed shutters that close the opening when the whole house fan is not in use. This keeps attic air from entering your home.
