For retrofit installations, the compact direct drive configuration allows greater system flexibility. These fans assure high efficiency as well as quiet operations. Airfoil fans are used in applications where ambient or elevated temperatures are involved such as chemical, power generation, metals, resource recovery industries, and so on. Applications include packaged equipment for cooling, drying, dust collection, recirculation and aeration systems. Airfoil Fans: Centrifugal fans are named so owing to their airfoil-profiled blades. Consult your Canada Blower Fan Engineers for above optionsВ tcffan.Chicago's direct drive airfoil plug fan offers a compact economical alternative to belt drive plug fans.Your Canada Blower Sales Engineer can offer technical advice along with recommendations for corrosion resistant applications. Fans with special coatings can be furnished per paint manufacturers recommended surface preparations, such as continuous welding, rounding of sharp edges, sand blasting, etc. CORROSION RESISTANT FAN CONSTRUCTIONДepending upon conditions, Canada Blower can furnish fans with special coatings, galvanizing, rubber coverings or special metal ventilator construction. Non-sparking construction type Everdur is also available. Offered for fans handling explosive mixtures, the type of construction depends upon the degree of spark protection desired.
