Alphair Cyclone Series
The comprehensive line of ALPHAIR Cyclone custom engineered centrifugal fans from Howden are perfectly suited to applications that require moving air at higher pressures or volume, or air that is comprised of hot gases (up to 1000F/540C), corrosive gases or abrasive particulate.

Key Benefits

  • The Cyclone series is made up of six unique Centrifugal Wheel families, each featuring a number of design widths, and ranging in size from 24" to 120" wheels diameters.
  • Wheels are engineered to operate at conservative stress levels and incorporate fabricated or spun shrouds while rotor designs feature scalloped center plates on large double width fans to reduce weight and inertia.
  • Single and double width designs are rated to air flows up to 1,000,000 CFM (470 cms) and static pressures up to 130 in.wg. (2,500 mmwg.).
  • The structures are continuously welded to CSA Welding Standard W59.
  • ALPHAIR offers several standard AMCA arrangements, as shown in AMCA Standard 99-2402. All arrangements are available with, or without inlet boxes.
  • Single width fans can be supplied in all arrangements.
  • Double width fans can be supplied in Arrangements 3 and 7.

Standard Features

  • Each Cyclone Series fan is customized to meet a specific set of operating criteria determined by the individual application.
  • Each fan incorporates materials selected for the application, from carbon steels to specialized materials such as stainless steel, aluminum, FRP, and other heat and corrosion resistant alloys.
  • Within the Cyclone series, ALPHAIR has developed six unique Centrifugal Wheel families, each featuring a number of designs widths, and ranging in size from 24" to 120" wheel diameters.
  • These wheels are engineered to operate at conservative stress levels.
  • The wheels incorporate fabricated or spun shrouds while the rotor designs feature scalloped center plates on large double width fans to reduce weight and inertia.
  • Single and double width designs are rated to airflows up to 1,000,000 cfm (470 m3/s) and static pressures up to 130 in. wg. (2,500 mm wg.).
  • The structures are continuously welded to CSA Welding Standard W59.

Optional Features

  • Stainless steel, aluminum, FRP, and other heat and corrosion resistant alloys.
