Three phase motors used are fabricated under NEMA (MG-,998) specifications, also meeting IEEE; Std 2 (R-996) utilized for efficiency determination. Recognized trademark ball bearings, integrated in cast iron floor mounting bearing blocks, selected for long durability at the highest rated RPM. Supporting base motor bearings is fabricated with high resistance galvanized steel. Base motor assembly to the fan frame is supported by means of antivibration blocks in order to reduce sound level and possible vibration of drive which could be transferred to the structure of the system. Venturi-propeller assembly is designed to provide great efficiency and sound level reduction. Outlet-base is made of high resistance and large gage aluminum, which provides rigidity to the assembly. With welded corners for higher robustness. In models and venturi inlet is made with highly rust resistant galvanized metal sheet.
