Onyx Series

Onyx series represent the next evolution in fan technology. Featuring our patented Bypass technology, Onyx fans are ideal for cooling schools, offices, theatres, galleries and large stores. Only Airius fans use this system to create strong columns of air that reach the floor, without any of the audio or visual pollution associated with primitive bladed fans.



The constant movement of air provides a powerful cooling effect, and can make your environment feel up to 7°C cooler on hot days.


Airius Onyx fans use our patented technology to achieve this impressive effect in a compact package. Onyx fans push a laminar column of air all the way to floor level. In addition to eliminating pockets of hot and cool air, it creates a constant flow of air to improve comfort.



Using a similar approach to airflow optimisation as that found in the latest generation of Rolls-Royce jet engines, Onyx fans achieve a big impact with minimal energy consumption.


Our patented Bypass technology increases the air draw through suction, maximising the air volume bypassing the fan motor, exponentially increasing air flow performance. This system is unique to Airius fans – and is one reason why our products far exceed the efficacy of primitive bladed fans.


Our Onyx fans use intelligent technology to move large volumes of air while consuming very little energy.


Compared to the costs of buying and operating air conditioning systems, Airius fans cost 90% less. And when used in conjunction with air conditioning systems, you can reduce your reliance on these costly systems and also improve comfort levels throughout your environment.


Airius fans are built to deliver maximum impact with minimum energy use. We use premium components, including EBM Papst motors, to furnish our destratification fans, which are designed and assembled in the USA.


We’re confident that your Airius fans will deliver the cooler and more comfortable environment you want. And with a 5-year warranty backing your Airius products, you can place your order with confidence.


Onyx fans are quick and easy to install in a wide variety of settings. Because they require no ductwork or infrastructure, they can be positioned perfectly without any additional labour or materials required.


These free-hanging units can be angled using the ratcheted handle, as much as 90 degrees from vertical.


Onyx series destratification fans are ideal for cooling spaces with ceilings up to 12m high.


Onyx fans are suited to a wide variety of applications, including educational facilities, retail venues, sports halls, workshops and offices.


A single Onyx fan can achieve destratification for floor areas of 60m2 to 120m2 – depending on the height of the ceiling and the nature of the space.


This means you can transform comfort levels in your environment without having to add a fleet of unsightly ceiling fans. Airius fans achieve impressive effects with minimal footprints.


Airius fans are the smart destratification solution. Using patented technology and premium components, Airius fans can make a huge impact from a compact package.

Onyx destratification fans can be used with the Airius 1 AMP, 5 AMP and EC wall-mounted speed controllers. This allows you to customise your installation to gain maximum efficiency from your Airius system in any climate.

Airius engineers can help you evaluate your options and select the most efficient and effective fleet of destratification fans to lower your energy costs and improve comfort in any environment.


All Airius destratification fans come as off-white (Cool Gray C) as standard. For installations where colour and aesthetics are a factor, Airius destratification fans can be RAL colour match painted to suit your unique application.


This colour-matching option, combined with our elegant designs, means that you can transform the comfort of your environment without impacting the aesthetics.



Airius destratification fans are designed to run 24/7. By running constantly, they prevent the fluctuations in temperature that occur when stratification goes untreated. In most cases, running the fans all day, every day, is the most efficient and effective way to maintain comfortable conditions.

When buildings are unoccupied for periods of time, Airius fans can be installed in conjunction with timers, integrated with a building management system (BMS) or used with wireless controls.


Onyx series destratification fans are available with either PSC (permanent split capacitor) or EC (electronically commutated) motors from leading manufacturer EBM Papst. EC motors offer optimal operation at less than 100% speed.

All motor options offer incredible performance and efficiency, giving you years of cost savings while consuming remarkably low levels of energy.
