The Air Cooled series of split ducted units shown are part of Dunnair’s range of high quality units
for every application. Dunnair has also become the first choice when individual engineering solutions are required.
Fast-moving and responsive, Dunnair supplies made-to-measure HVAC solutions to a growing number of high profile developments across Australia.
Dunnair research and development plus a strict quality control program have been fundamental to their growth, success and reputation. Dunnair units are manufactured in accordance with strict quality control standards and are MEPS rated and developed for Australian conditions.
Dunnair’s modern factories manufacture 16 separate product lines and some 600 different models. Dunnair can supply most products the HVAC industry requires.
The recent acquisition by Air Change, a company known for it’s award winning innovation, is proof that the company is working continuously to improve its product range and the efficiency of its products.
Dunnair will engineer and manufacture equipment to suit the application and building
design. No challenge will go unaccepted. We will design and make special products as required for the building, mining, transport and maritime industry.
We employ mechanical engineers in all sales offices in Australia. Their role is to supporting designers to achieve their goals.
Our promise to system designers is: “Tell us what you need and we will work with you to deliver”.
