The KC series are heavy duty tubular centrifugal supply and exhaust fans designed for class I and II performance with reliable air movement in comercial and industrial applications. ATC centrifugal in line fans are available in 9 sizes with wheel diameters from 10 ¼” through 24 5/8”, different performance classes, rotations, discharge and mounting positions, offering the line of most versatile, quiet, energy efficient and space saving fans which can handle a wide range of air volumen and pressure in the global market..

Construction Features

• Housings, inlet cones, drive stands, flanges, weather proof motor and drive cover are made of air tight heavy gauge all welded steel construction
• Backward inclined non-overloading wheels are constructed with welded steel, stainless steel or aluminum, statically and dynamically balanced at the factory and designed for optimum performance for most operating conditions.
• Electrostatically applied powder coating is Standard on all ATC fans. For special requirements, please contact the factory.
• The fans are available in 2 different discharge and construction arrangements (Horizontal, Vertical), 2 distint type of mounting positions (Floor mounted with rubber – in – shear or spring type isolators; ceiling mounted with spring type isolators), 3 motor positions for floor mounted (0°, 90°, 270°), 4 motor positions for ceiling mounted (0°, 90°, 180°, 270°) and clockwise (CW) or counter clockwise (CCW) wheel rotation.
• Self-aligning heavy duty, pillow block ball bearings are designed to operate under the most severe atmospheric conditions and are supplied by the most prestigious world wide manufacturers.
• Shafts are designed for long life in different diameters and lengths, turned, ground and polished of solid SAE 1045 steel for smooth operation, key-wayed on each and are protected with a corrosion resistant coating.
• Adjustable steel motor plate pivoted at one end for ease of belt tensioning.
• The KC centrifugal series are the ideal choice for the general ventilation applications with the space saving advantages of an axial type fan in both belt drive (KCB) and direct drive (KCD) design.
• AMCA classifications for spark resistant construction where hazardous, explosive or flammable conditions exist.
• Type A- All parts of the fan in contact with the air or gas being handled shall be made of non-ferrous material.
• Type B- The fan shall have a non-ferrous bearing cover and wheel about the opening through which shaft passes. Ferrous hubs, shafts and hardware are permitted.
• Type C- The fan shall be so constructed that a shift of the wheel or shaft will not permit two ferrous parts of the fan to rub or strike. Fans for this condition will be furnished with a nonferrous inlet cone and bearing cover around the shaft opening.
