Destratification fan system for acoustic ceiling. Our Air Pear 10, 15, 25 and 45 sized fans are available in a 2 ft. x 2 ft. ceiling tile package.

Product Overview

Airius offers the only air turbine destratification fan featuring a venturi nozzle design and patented stator system to ensure a laminar non-turbulent column of air is delivered from the ceiling to the floor below where we live and work. The combination of housing shape, patented stator, energy efficient motors, control selection and wide product range is what makes Airius the world leader in destratification technology.

In our Suspended Ceiling model, a dome separates the Air Pear from the air space (plenum) above the ceiling grid. Only the conditioned air in the room below the unit is mixed.

At delivery, the Suspended Ceiling fan speed can be preoptimized for your building’s layout. We also offer multiple control options, including variable speed or wireless control for use by staff or with energy automation platforms.

    Iam in need of this fan. What would be the cost in India? Where i will be able to get the fan in India.

  • Avatar Wayne Donaldson says:

    I am interested in trying some of your suspended ceiling units in a group of our classrooms to see the effects and evaluate for a long term plan to add these in all classrooms in the district.

    I have an office area that is a portion of a pre-engineered building system. Because of the lighting and office heat generated the area above our ceiling is quite often warmer than the air below the ceiling. Can I physically remove the “dome” during the winter months, and replace it during the summer when I want to keep that warm air up there?

    I know this sounds weird, but I am just curious.


    • Sam Smith Sam Smith says:

      The dome should always be used to separate the plenum space from the conditioned space below. Check with an inspector and local fire codes to see if this type of use would be appropriate. There are some cases were removing the dome is acceptable. One of those is with dropped ceiling “clouds” that hang in the space and do not span from wall to wall. In this situation, removing the dome to capture stagnant stratified air is acceptable.

    Is there a trim option if these are installed in a sheet rock ceiling?

  • Avatar Ray Morton Jr says:

    Do I need a switch or is there a remote switch?

    • Sam Smith Sam Smith says:

      Ray, we’ve reached out via email to get a little more context on your specific situation. To answer a more general question about switches: No switches are provided with the fans. A simple wall switch, like you would use for lights, can be used to turn the fans on or off.
