Frequently Asked Questions

Having an issue? Below are some of the commonly asked questions about Flexxaire and our variable pitch fan. If you don’t find the answer to your question, scroll down to submit your specific question.

What machines do you have fan designs for?

We have a vast library of fan designs covering many industries and applications, and if we don’t have a design for your application, chances are we can design one for you.

What is the typical life of the fan?

The Flexxaire fans should last the life of the engine. A yearly visual inspection is recommended. Service parts are readily available if required.

What are the fan's maintenance requirements?

Our fans require no maintenance. We use high-quality synthetic lubrication, and our hub is fully sealed to keep the lubrication in and dirt and debris out.

What is the delivery time?

If we have the design for your machine already in our records, we can have your fan ready for delivery in 2 weeks or less from time of order. Otherwise, if it is a new design, we require 3 weeks (engineering review and new design).

Can I install the fan myself?

Yes, we supply all necessary supporting documents to make for a straightforward installation.

What diameter range do you cover?

Our fans cover the diameter range of 16” (425mm) – 61” (1550mm).

Are your parts readily available?

Most service parts are readily available, and if we have your order in the morning, we can have it packed and shipped the same day.

Where can I find my fan serial #?

The serial number can be found on the front face of the fan on a white label.
