The premium Nidec-Emerson 1/2 HP sealed ball bearing motor features a very important component, a 10% larger internal stator and rotor 'stack' for more horse power than standard 1/2 HP motors. This extra 'stack' powers it to run faster than any other livestock fan that we know of. As an added benefit, the Turbo motor runs 11% cooler than competitors 1/2 HP motors, this allows cooler air output from the Turbo. All while only drawing 4 AMPs of electricity, equaling a super-efficient fan. The Problem-Free Guard... Built for Longevity! Constructed of extra-thick 7 gauge and 11-gauge steel wire that is formed into a continuous one-piece spiral formation for reinforced strength that is not provided in other fans. This engineered craftsmanship has proven to create strength that is virtually crush-proof! Baked-on powder coat treatment for corrosion resistance and a cleaner appearance. No other fan guard withstands the rigors of the show road like the Turbo. | Sullivan Supply Inc Turbo Fan | Size 24"
