When you talk to your Sales Engineer or our Customer Service Department, you are just a heartbeat from our shop floor. We will custom design a fan to your exact requirements, build it here at our Burton, Ohio factory and then ship it directly to you

I have a broken fan. Can I replace just the blades or do I need to replace the whole fan?
If your fan hub is in good condition, you may be able to buy replacement fan blades, though we do not recommend aluminum replacement blades for balancing reasons. In order to achieve superior performance, you may want to consider buying a new fan that is professionally assembled and balanced.

Can you supply a replacement for one of your competitors’ fans?
Normally, we can design a fan optimized for your particular application once we determine your cooling requirements. Contact your Sales Engineer for more information.

How will this fan perform? How fast will it spin? How much CFM can I generate? How much static pressure can I generate?

Simply download Optimiser here or contact your Multi-Wing America Sales Engineer.
