Opal Series

Precision-engineered airflow and silent running. The Opal series circulates the air and creates constant movement to keep you feeling cool in summer and warm in winter. Unlike primitive bladed fans, the Opal destratification fans create powerful columns of air that reach all the way to the floor.



The Opal series fans create laminar columns of air that circulate the air around your environment, equalising temperatures and humidity at all levels. They greatly reduce stratification, the layering effect that occurs when warm air rises and pushes cooler air down, leading to temperature imbalances in your buildings.


Whether you need to reduce temperatures in summer or improve the performance of your heating, the Opal series achieves a big impact with very low power consumption – and very little noise or visual disturbance.


Opal series fans employ the same unique technology that our larger units use to transform comfort levels in warehouses and aircraft hangars, but in a smaller form factor that is suitable for residences, care homes, hotel rooms and other small spaces.


While primitive bladed fans churn the air around the ceiling, Airius Opal fans create a laminar flow, which means they push the air downward in a tight column. And because Airius fans are enclosed, they don’t produce the distracting strobing effect of traditional fans.


Airius fans achieve their impressive results through the application of our patented technology. Only Airius fans feature our stator vane technology and Venturi nozzle.


This design allows Airius fans to move large quantities of air, quietly, while drawing very low levels of power. This means you can run your Opal fan 24/7 without worrying about the impact on your energy bills.


Weighing just 2kg, the Opal series is easy to hang in small spaces and from a wide variety of ceilings.


Because Airius destratification fans do not require any ducting or additional infrastructure, they are quick and easy to install.


Every Airius fan features premium components, including electric motors from EBM Papst in Germany.


By using the best components, we can achieve remarkable energy efficiency, and can confidently offer 5-year warranties on all fans.


In smaller spaces, the sound of whirring or chopping fans can become a nuisance, and it may deter users from running the fans overnight.


With the Opal series of destratification fans, you don’t have to choose between comfort and quiet. You can enjoy perfectly balanced temperatures and humidity throughout the night and day.


Opal series fans are ideal for ceilings between 2.4m and 7m high. This makes them ideal for a wide range of deployments, from small residential properties and care settings to larger hospital wards and retail units.


Airius engineers can help you select the correct quantity of Opal fans to perfectly balance the temperatures and humidity in your properties.


A single Opal fan can achieve up to 40m2 coverage, depending on the height of installation and the nature of your environment.


Airius engineers can help you determine the ideal quantity of Opal destratification fans to improve comfort in your facilities.


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

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.

These subtle colour options help the Sapphire destratification fans to sink into the background. You might forget the fans are there, but you will always appreciate the constant improvement to comfort.


Airius destratification fans are designed to run 24/7, 365 days per year. By running constantly, they prevent the fluctuations in temperature that occur when stratification goes untreated, and ensure that your building is comfortable when people first arrive, to the moment they leave.

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.


Opal 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.
