Features & Options

airius fans air pear patented multi vane stator and nozzle

Patented multi-vane stator and Venturi nozzle

Old style ceiling fans or a simple tube design generally will not offer adequate throw for destratification. Airius fans feature a unique nozzle design and patented stator system to ensure that a column of air is delivered from ceiling to floor — where we live and work. With any axial fan, there exists a radial component to the air flow causing it to spread laterally and lose velocity when leaving the nozzle. Airius’ patented fixed blade stator sits below the fan to transfer this rotational energy into linear motion exiting the nozzle. Having the airflow energy in line with the fan axis promotes a tight air column and maximizes the throw. In addition to the stator, the slightly tapered nozzle increases the exit speed and allows for the air throw to be maximized even further.
airius fans q series motor mounting

Unique motor mounting and intake

The Q series fan design suspends the motor at the intake without using a fan grille. By eliminating the grille, we reduce the turbulence induced into the blades to keep the fan quiet. Without a grille, less intake area is blocked which maximizes airflow. Because this fan does not have an intake grille, it should always be installed in a place where occupants can not reach it.
airius fans quick service installation

Quick and easy installation

Complete with a 6-foot cord and plug for 120V fans, installing a Q Series fan is quick and easy. Mount an electrical j-box/receptacle near the intended fan location and use one of the recommended mounting methods to hang the fan from the supplied eyebolt. Additional low voltage wiring may need to be installed for control of an EC motor or eliminated with a wireless control option.

6 ft. steel leash and anchor point for safety

Every Q series fan is supplied with a steel safety leash pre-installed. The safety leash acts as an additional restraint in the case of catastrophic failure of the main attachment point. Airius is the only small destratification fan manufacturer with this safety feature.
airius fans air pear basic motors

Standard AC motors and controls

Our standard AC motors are a great option to keep things simple. Controls for these types of motors are installed in-line with the power circuit feeding the fans. Several control types are available, from simple wall mounted controls to our Smart TRIAC that can adjust speed using: dip switches for fixed speed, 2-20mA current, 0-10VDC, or high and low temperature sensors that adjust fan speed based on the temperature difference. Please see the following information sheets for specific details.
airius fans air pear premium motors and controls

Premium EC motors and controls

Our premium EC motors, made by ebm-papst®, are a great option for maximum efficiency and controllability. EC fans maintain higher efficiency across the entire speed range when compared to traditional AC motors. Controllability of EC fans can be through a direct 0-10VDC wired connection, using our Pearlink Wi-Fi based app, or integrated into an existing automation system over BACnet/IP.


Q Series fans are available in three standard colors: Off white (Cool gray 2C), gray (gray 432C) or black. Custom colors will be considered for large bulk purchases. Contact Airius for further details. If you need small quantities of fans with custom colors, look at our Designer Series fans.
