Airius Diamond series fans pack a lot of power into a small package. Highly energy-efficient and remarkably quiet, these destratification fans create a constant flow of air around your building.
In addition to eliminating hot pockets of air, Diamond destratification fans can make your space feel 7°C cooler on hot days (>36°C). This cooling effect can also extend the lifespan of plant and machinery, as well as other infrastructure such as lighting systems.
The flexible installation options for Diamond series fans means they can be easily deployed in any space. They can also be angled (up to 90°) to suit the cooling needs of your space.
Diamond destratification fans are ideal for a wide range of buildings and use cases, and are particularly suited to sports arenas, gymnasiums, airports, agricultural facilities and factories.
By using premium components and our patented designs, our Diamond series of destratification fans can achieve powerful cooling effects while using minimal energy.
Using Airius destratification fans instead of air conditioning can dramatically reduce your energy costs and significantly improve your carbon footprint. And when used in conjunction with traditional air conditioning systems, the movement of air can improve the performance of your system, simultaneously improving comfort levels and reducing energy bills.
Diamond series fans can be used for cooling environments with ceilings between 8-25m high. They can achieve destratification under ceilings as high as 20m.
While primitive bladed fans create a great deal of noise and visual disturbance, and are only capable of churning the air near the ceiling, Airius destratification fans discretely create a column of air that descends all the way to the floor. This column has enough force to circulate the air at ground level, but without kicking up dust or creating a draughty environment.
Airius Diamond series destratification fans can achieve coverage of between 120m2 and 300m2, depending on the height of installation.
Our engineers can help you evaluate your cooling needs and design the ideal package of Airius fans to improve comfort and reduce energy costs in your facility.
Our new Bypass technology is an Airius-patented component of our new Diamond series destratification fans. It is an approach also found in the engines powering the latest generation of Dreamliner passenger jets.
