SQAD / SQBD Direct Drive

Direct Drive SQAD/SQBD fans combine the performance and efficiency of Chicago's versatile "Square" Fans with the advantages of a compact directly driven arrangement. With the fan wheel mounted directly onto the motor shaft maximum efficiency is constantly maintained. Belt noise, power loss, maintenance and troublesome adjustments are eliminated.
Chicago's Direct Drive Fan is available as a SQBD with backwardly inclined blades in addition to the airfoil bladed SQAD. With the choice of two types of wheels application duty can be matched precisely. Also, the different performance characteristics of the two wheels allow for a wider performance range at standard synchronous motor speeds. The compact SQAD / SQBD fans are used in diverse OEM applications, from packaged forced air and dust collection systems to pressurizing and aeration installations.
