Fan Retrofit Solutions

Customers may need to upgrade their existing fan systems to improve performance, fan efficiency or to meet new process air requirements in their plant.

In these cases substantial cost savings may be achieved by replacing the existing impeller with a custom designed impeller that fits into the existing fan housing. CFW’s experience in air applications together with its extensive fan testing capabilities has provided our customers with unique solutions when applying fan retrofit technology. Fan efficiency, air power density and impeller mechanical reliability is typically improved, and the aerodynamic performance is guaranteed. An engineering solution using the existing fan casing, drive motor, fan shaft and bearings may often be achieved. A thorough analysis of the fan and system must be done beforehand when applying this technology. This includes site performance testing and a detailed inspection of the fan installation.
