Drive rrangements rrangement Versatile and rugged V-belt drive arrangement with the motor mounted separate from the fan base. Maximum temperature of standard fan is 300. Maximum temperature of heat fan is 600 *. Specify M motor position designation (see below) and fan RPM when ordering fan complete with drives and motor. rrangement 9 ompact V-belt drive arrangement with the motor mounted on the fan support base. This arrangement will accept a full range of motor frame sizes through 84T. Maximum temperature of standard fan is 300. Maximum temperature of heat fan is 600 *. Standard construction is with the motor on the right when facing the end of the shaft. Indicate motor and mounting description (right or left) when ordering. * Heat fan includes an aluminum-bronze Dura alloy wheel, 240 aluminum two-piece heat slinger, and heat shield. The heat slinger protects against transfer of heat through the shaft to the bearings. rrangement 4 The most compact and least expensive direct drive arrangement with the wheel mounted directly on the motor shaft. rrangement 4 fans are available in a limited number of models. Minimum motor frame size is 48 for the 8" and 56 for the 0" and 2". Maximum temperature of standard arrangement 4 fan is 80. or direct drive heat fans (rrangement 8 only), please consult the factory. Motor Positions The drawing at right illustrates the M motor position standards for rrangement fans. The location of the motor is determined by facing the drive side of the fan and designating the motor position by letters W, X, Y, or Z.
