Fan Propeller Selection

fan propellerFans are dynamic machines, subject to wear, vibration, and other issues due to constant movement. It is an unfortunate fact that fan propellers can become broken or damaged during operation. Any number of occurrences can cause a fan propeller damage, ranging from an object striking it, to build up of residue from the environment in which the fan operates.

Another unfortunate fact is that fan propeller damage can happen at a critical time. In these cases, fan failure can bring production to an expensive halt. It is important that you know how to get that fan propeller replaced quickly, to get the fan back in operation as soon as possible.

Air Solutions is Here to Assist with Fan Propeller Replacement

When you need fast fan propeller replacement, Air Solutions is your source for quality-made propellers and fast turn-around. To make the ordering process easier, here is a quick fan propeller selection question list that you can use to prepare. This fan propeller selection “cheat sheet” will make securing your replacement propeller simple and get you back in production in no time.

1. What is the Fan Propeller Size/Trim Diameter?
Be sure to measure the diameter of your propeller from tip to tip. Keep in mind that the diameter of the propeller is not necessarily based on the size of the fan.

2. What is the Fan Propeller RPM?
Sometimes the RPM of the propeller is unknown. In the case of a belt driven application, you can provide the pulley sizes and the motor RPM. In the case of direct driven fans, the motor RPM will be equal to the fan speed.

3. What is the Bore Size?
The correct way to determine bore size for a belt driven fan is to measure the diameter of the fan shaft. For direct drive fan applications, the bore size will be the same as the motor shaft size.

4. What are the CFM Requirements?
To order a propeller that will deliver the optimal air requirements, knowing the CFM requirements is extremely helpful. If CFM is unknown, a propeller can be made to deliver the optimal CFM that the fan’s motor HP can deliver without becoming overloaded.

5. What are the Static Pressure Requirements?
This important detail will assure that the propeller will deliver optimal static pressure without overloading the motor. Be sure to note if the fan is operating with ductwork attached or any other restrictions that would affect CFM.

Other information that would be helpful if you can provide it will be:

  • Construction Material
  • Operating Temperature
  • Bore Type
  • BHP Requirements
  • Hub Location – air entering or air exiting
