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.
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.
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.
Fan arrangements define the way a motor drives the fan, and how the motor mounts to the fan, based on AMCA standards. They can also be application-specific, as with the Arrangement 4V Top Mount Fan.
When designing and installing your industrial fan, it is essential to consider the full system and long term needs, including surrounding ductwork and fan maintenance.
Centrifugal fans, with their moving parts and sometimes heavy-duty air processing, require regular fan maintenance in industrial applications. You might need to clean it, you might need to balance it, you might need to repair a part, or even retrofit the fan. At some point, you’ll need access to work on the wheel and shaft. If you’re not sure you’ll be able to get into the access doors in your application, split housings might just save the day.
Industrial fans have a special job to do when used in a dust collection application. They need to get the dust-laden air past the filters in the dust collector baghouse. The system pressure varies based on how “dirty” the filters are, and you can adjust the fan speed accordingly. Properly adjusting the speed can reduce your overall power consumption, but that depends on whether or not you place the pressure gauge in the right spot.
You’re probably not going to be looking for a lot of “peace and quiet” on the shop floor, but you and your employees and colleagues are working there for hours at a time. You might even need to have a conversation, or just hear yourself think. Industrial fans can add to the noise level, but fortunately, you can accomplish fan noise reduction by way of an industrial fan silencer.
We often get questions from our customers about how to determine the best synchronous speeds for belt-driven industrial fans. The answer depends on the fan’s operating speed and motor horsepower.
