New Impeller Design
All fans can be modified to run more efficiently in a variety of ways, including tipping/de-tipping the fan blades and changing the fan blade design. More designs available to cover every permutation of pressure and volume likely to be required, at temperatures of up to 450°C. The narrower fans at the lower flow end of the range are fitted with parallel shrouds to give greatest stability of performance, while the wider models have tapering, high-strength shrouds designed to prevent stall. Partial or full liners of abrasion-resistant steel, chromium or tungsten carbide can be fitted, and stainless steel liners are also available for scrubber applications.
Retrofit Impeller
All fans can be modified to run more efficiently in a variety of ways, including tipping/de-tipping the fan blades and changing the fan blade design.
In many cases a
more efficient fan impeller can be retrofitted into the existing fan housing
while re-using the existing foundations, bearings, motor, and coupling.
