Bearing life is a major component in overall fan life. Maintaining proper lubricant levels with appropriate lubricant for the application will extend bearing life and require fewer replacements. A simple preventative maintenance program implemented for your fan can save thousands of dollars in replacement parts over the course of several years. Such a plan would involve such steps as regular lubrication of fan and motor bearings, connection inspections, and vibration analyses.

AirPro recently built a couple of high pressure blowers for a US paper mill upgrading their power-generating boiler system from coal to biomass. The blowers are supplying the combustion air for the new burner system. Special attention had to be given to proper pressure and air flow as the blowers were required to be located a floor below the actual boiler due to space restrictions. AirPro supplied the fan skid complete with inlet filters/silencers and installed the damper/actuator system, designed and supplied by the plant manager/project engineer overseeing the project.

Story: The following high temperature fan was built for a power company in Colorado. Several years ago, the customer had purchased a Selective Catalytic Reduction (SCR) system with fans provided by a competitor. What followed was a continuous string of unresolved bearing failures that resulted in unreliable performance and unacceptable maintenance costs. Finally, AirPro was called in to review the application and offer a solution.

The following plug fan was rebuilt for a US steel company that heat treats customer supplied castings for automotive companies. After this user’s fan from another fan supplier failed, AirPro was asked to produce a dimensional & functional match. AirPro’s engineers reverse engineered the “model fan” and produced a “match.”

Fan selection software helps engineers select and specify a fan that will deliver the performance needed in the process application.

Waiting on fan manufacturers to get quotes back to you can be stressful. Frequently, you do not have the time — days or even hours — to wait for a quote. Fan buyers have another option though: Most industrial fan/blower companies offer fan selection software, available via the Internet on company websites, or offered as a program to be installed on your computer. No matter the source though, it is important to do two things before using the selection software to find the appropriate fan for your application.
