Product Details

Comair Rotron AC Axial Fan

The COMAIR ROTRON major series axial fan features outstanding airflow performance in high-pressure systems and all include a permanent 3350rpm split capacitor motor. It has a supply voltage rating of 230VAC 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 of time (51,000hours 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. These fans have a power consumption rating of 30W.

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, the axial fan would be mounted directly to the motherboard and blow air directly at the processing unit. A constant high-pressure of airflow ensures PC will continue to running smoothly.

Why choose a ball bearing axial fan?
Ball bearings are the 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.
