It’s all about selling fans

Good fan selection software is vital to fluid and successful sales.
If you don’t already have software, your competitors almost certainly do.  
If you do have software, is it up to the job? 

Business & sales-orientated

A happy sales representative is a productive one and we’ve designed this product with them in mind.  It goes without saying that the fan, motor and VFD selection are vital, but so is the business side. It quickly gets the salesperson the results they need to sell your products and give you the edge over your competitors.

Fast and accurate

With nearly forty years of working in the air movement industry and a background in fan engineering, we’re experts in our field. Our algorithms are based on recognised standards (ASHRAE/AMCA), so you can be sure of accuracy. It’s quick and intuitive to use to create those BOMs and technical  submissions. 

Quick and easy integration

Do you need something now and don’t want to wait months for a custom build? We aim to get our clients up and running within a month of their order being placed (based on the standard system). It’s not a problem if you need customisations, we add them on after you’re already operational.                                    


Will it support your fans?

Air movement using fans obeys the physics of the fan affinity laws.Our selection software is based on the fan affinity laws so it will work with your fans.
It doesn’t matter if the application is HVAC, petro-chems, aeronautics, automotive, mining etc, the principles are the same. We also provide specialist customization where required.


Propeller, vane, jet, tube fixed/variable pitch & speed. All types supported. 


Plug plenum, housed centrifugal blower, custom. Radial, airfoil, forward/backward curve. All types supported.


High volume, pressure & temperature. Mixed flow. Low sound, high efficiency applications. Specialist environments (hostile/clean)


Fixed/variable speed. Direct drive AC Induction/VFD & EC Motors. Direct drive/Belt drive.


Desktops, tablets & mobiles

When we designed this software we were looking to the future. In business, as in life, people are leaving their desktops behind and using tablets and mobiles.  The expectation is that even everyday communication can be done on the move.   

We have designed our software to work on all standard platforms in use today. This means that in years to come, people can still make fan selections on their preferred device, at a time of their choosing. Flexibility and accessibility is key.


Language and global reach

The software currently supports 8 different languages and we are constantly adding new ones. So it doesn’t matter where you are in the world, we can support your native language.

If you export your fans to other countries, you can allow your people to use the software in their native language which can really streamline your sales operations.

Computair already supplies software to the countries shaded blue.
