Active since 1980.

Computair has been the original innovator of HVAC software since its inception in 1980 and continues to improve and expand the business of our clients cementing our status as a global leader of this sector.


Web site

Computair announced the release of their ‘new look’ corporate website. As part of our ongoing web activities we periodically revamp our website in line with the current design practice of the time. You’re looking at it and we hope you like it!


Computair announce a new enhancement to their web-fan software for manufacturers who provide variable width fan solutions.

The addition to our proprietary fan selection algorithm allows fans to be selected with an operating point on or close to the peak static efficiency slope by adjusting the wheel width. In a world where efficiency is becoming more important this helps drive down running costs and gives the fan manufacturer a definite sales edge on their competitors.

fan dll

Computair announce a new enhancement to their web-fan software that allows for the creation of a ‘fan DLLs’ with just one click! This exciting new feature allows web-fan users to easily create fan dll’s and a web-service of their fan inventory.

These can then be used by air handler design software to include our client’s fans. For some this really opens up some new sales opportunities
