Howden American Fan Company, a manufacturer of fans, blowers, compressors and rotary regenerative heat exchangers, offers a wide range of fan product lines ideal for serving industrial boilers, gas turbine installations, and heat-recovery steam generators in combined cycle installations. Howden works closely with original equipment manufacturers (OEMs) to supply a high quality industrial product at a competitive price, designed to meet specific air flow and pressure requirements. Also available are start-up and commissioning and after-market service and repairs.
Consulting closely with OEM engineers, Howden’s experts review such performance criteria as air flow, resistance, temperature, and elevation and make recommendations on the entire fan package, including fan selection, base, and mounting. Automated software assistance is available for entering fan parameters and reviewing available options and costs.
Howden’s direct-drive fans include the popular industry-standard AF line of cast aluminum medium pressure blowers, nine types of backwardly inclined fans, as well as turbo pressure blowers and industrial exhausters. Also available are dual skid-mounted fan assemblies, including two fans connected to a common diverter damper, all mounted on a common unitary channel sub-base. This popular choice provides one fan for everyday operation and one fan to serve as a standby.
Priding itself on flexibility and willingness to develop non-standard packages specifically tailored to meet the application, Howden has designed turbo pressure blowers with an inlet filter silencer as well as an integral damper for flow control. Howden has also provided special nondestructive structural integrity testing and certification of the wheel and shaft to ensure the equipment will be long-lasting and stand up to its intended use.
Howden also builds fans with housing percentage widths at 5 percent increments from 60-100 percent. Changing the fan construction so it can handle lower volumes without slowing fan speed eliminates any need for use of a belt drive, which can reduce maintenance costs.
