Howden - Model Alphair Cyclone Series -Heavy-Duty Axial Fans
Jetstream Axial Mine Fans (AMF Series) are heavy-duty axial fans designed specifically for main mine ventilation These robust adjustable-pitch fans have been designed to deliver up to 1 million CFM against 14 inches total pressure. Ranging in sizes from 76 1/2" to 148", this fan line delivers high efficiency and reliable service.
Each CYCLONE fan is customized to the specific set of operating criteria of each individual application. Construction materials include: carbon steels, stainless steels, aluminum, FRP and other special corrosion and heat resistant alloys. Each fan combines the ideal mix of ruggedness, reliability, efficiency, maintainability and economy that are the hallmarks of every Howden fan.
The Cyclone series offers six centrifugal wheel designs, in sizes ranging from 24" to 120" wheel diameters. Single and double width designs are rated to handle up to 1,000,000 cfm and static pressures up to 130 inWg.
