Axial PC fan MRS series

The MRS Series fans are large airflow, high static pressure and high-efficient AC input axial fans, available in frame sizes ranging from 5.51 in. to 9.84 in. (140 mm to 250 mm). Models are also available with built-in alarm circuits that can detect fan rotation abnormalities and respond by outputting alarm, allowing for service to be performed. A Variable Flow model is also available in a frame size of 7.09 in. (180 mm) and features an internal power control device which allows adjustment of airflow to match the cooling requirements. Cooling Densely Mounted Devices with One Fan Effective cooling is possible using a large cooling fan offering high static pressure. Using one large axial fan is more efficient than using multiple small axial fans. they are also suitable for equipment with high blower, high duct air flow and high installation density. Low Speed Alarm Types An alarm is output when the fan speed drops due to the service life of the fan or ingress of foreign objects. This makes it possible to order and replace the fan with a new one before it stops. If multiple cooling fans are being used, it is possible to only replace the cooling fan with decreased cooling capacity. Even if the cooling capacity of the fan decreases, the effect on the equipment can be minimized.
