With less than a month to go in the year, we can’t wait any longer to report the good news about our on-time delivery averages for 2019. It’s our first full year designing, building and shipping centrifugal fans and blowers with on-time delivery to industrial and OEM customers as our number one manufacturing metric. The results are making us as happy as Christmas morning.
When comparing forced draft versus induced draft industrial fans, the primary difference boils down to push versus pull. Forced-draft fans focus the pressure and volume at the outlet of the fan to push air through a system, creating positive air pressure. Industrial induced draft fans operate by focusing the pressure and volume at the inlet of the fan to pull air through a system.
All companies and jobs are not created equal. When you own the company, when you trust your colleagues, when you know your customers, you may start feeling right at home. The family culture at AirPro Fan and Blower Company is a win for our employee/owners, our customers and beyond.
Spark-resistant fan construction is essential in many industrial fan and blower applications. These include applications where the fan is handling explosive materials or where the fan is installed in hazardous environments. For example, dust collection applications commonly require some level of spark resistant construction due to the explosive nature of dust.
RTD Temperature Sensors can prevent complications that could otherwise lead to bearing failure. Maintaining proper temperatures, along with vibration monitoring and proper greasing, optimizes the longevity of your bearings so they reach their L10 potential.
Adding vibration monitoring can lead to extended bearing life, and ensure your bearings reach their L10 potential. Vibration velocity measures in inches per second (IPS) how the equipment in question is being fatigued from vibration, ultimately influencing its longevity. The standard IOM (Installation, Operations, and Maintenance) manual recommends keeping vibrations under .124 inches per second for industrial fans operating in the installed state.
Fan bearing maintenance helps increase longevity and potential to reach the fan bearing’s full L10 life. Stated as a number of hours, L10 life indicates the life expectancy with 90% confidence that the bearings will meet the expectation. The higher your L10 life, the longer your bearings should last, provided you maintain your bearings.
The radial blade fan wheel in an industrial pressure blower helps move material-laden air at medium to high static pressures and stays clean in the process. That includes everything from light particles to heavier materials that can be sticky or abrasive, without compromising the fan wheel integrity.
Over our years designing, developing and delivering custom centrifugal fans and blowers for industrial applications, we have learned that no detail is too small in the specification process. This holds true when we talk about motor bearings too. There’s a specific nuance to consider when selecting motors for high horsepower belt-driven fans.
How do you determine the right motor speed for your industrial centrifugal fan? You’ll need to consider your fan’s drive arrangement and one more factor that frequently gets missed: frequency of the motor’s input power.
The key indicator for determining fan motor size is fan brake horsepower (BHP), which represents the force needed to brake, or stop, the motor. This is the minimum amount of power needed to operate the fan.
The Arrangement 7 fan is center-hung with the impeller mounted between two bearings and an integral inlet box to direct the air into the fan from above or from the side. This fan arrangement is optimal for use when your application requires large fan impellers and/or when you want to go the extra mile for increased fan life.
Fan arrangements define the way a motor drives the fan, and how the motor mounts to the fan, based on AMCA standards. The Arrangement 7 Fan offers a maintenance-friendly and reliable design for fans with larger impellers, as the impeller is center-hung between two bearings. The entire fan assembly is assembled on a common base and can be either belt or direct drive.
