Motors located out of the high temperature zone with in-built protection against shaft transmitted and/or radiated heat. In larger sizes, belt drive can make the motor even less vulnerable to the heat, which then only reaches the impeller bearing.
The type of impeller used depends on the application. In general a scroll housing will have forward-curved, and an open plenum will have a backward-curved impeller.
Hot air circulation within packaging equipment, printing dryers, industrial washing machines, kilns, industrial and laboratory ovens, environmental cabinets, laboratory incubators (low temperature air circulation).
