COMAIR Rotron Major DC Axial Fan

The COMAIR Rotron Major series axial fan features an outstanding airflow performance in high-pressure systems and all include a permanent 4200rpm split capacitor motor. It has a supply voltage rating of 24VDC and dimensions of 171.4mm x 150.4mm x 50.8mm. It has an extended ball bearing life, which ensures fault-free use for a significant period (70,000 hours at 40°C). This ensures COMAIR Rotron AC fans provide a flexible and dependable cooling solution for applications that require an axial fan to be mounted in any axial position. This fan has a power consumption rating of 39W.
What is an axial fan used for?
An axial fan is used for both, cooling and ventilation purposes. The impellers or blades rotate around a parallel axis and force air to move in an axial position, allowing air to move both, in and out. As an example, on a desktop PC, an axial fan can be mounted directly to the motherboard and blow air directly at the processing unit. A constant high-pressure of airflow ensures the PC will continue to running smoothly. This axial fan can also be used in various other applications, such as:
Refrigerators
Enclosed server cases
Air conditioners and other ventilation systems which use ducting
Why choose a ball bearing axial fan?
Ball bearings are a more common choice over ceramic and sleeve bearings. This is mainly due to the ability of the fan to be mounted at both horizontal and vertical positions, especially in applications which either need to be mobile or have to be suspended in an unnatural position. Another highlight would be the life expectancy, a ball bearing axial fan would last significantly longer than its sleeve counterpart.
What is an automatic restart?
As an example, if the fan locks up while the motor is still running, this can cause an increase in coil temperature. The automatic restart function can temporarily remove power to the motor preventing unwanted temperature rise. Once the locked fan rotor is released, the fan restarts and resumes running at its normal operation and speed.
