The EMU Series AC axial fans offer lower power consumption by utilizing a brushless motor. A wide voltage range can be used, single-phase 100-240V (50 / 60Hz), and the same performance characteristics are obtained regardless of the frequency used.
By using brushless motors, power consumption is reduced by approximately 68%
By using brushless motors, heat generation can be reduced and unit life is increased 2.2 times*
Wide Voltage Support
Can be used with single-phase 100~240 VAC (50/60 Hz) power supply. The same characteristics can be achieved regardless of the frequency used.
The mass of the fan has been lightened by approximately 45%* by using resin in the frame.
*compared to MU1238A-21B
No grounding is required due to the double insulation structure.

An alarm is output when the fan rotation speed drops below the alarm activation speed due to the life of the fan or contamination by foreign particles. This allows you to arrange and replace the fan before it stops. Even if the cooling capacity of the fan is reduced, the impact on the equipment can be minimized, contributing to improved reliability of the equipment.


Thermostats (sold separately) make it possible for fans to operate only when cooling is necessary. Thermostats provide energy-saving by automatically stopping fans for example, at night, when the amount of heat generation declines following the load rate's decline in equipment, or in winter, when the ambient temperature drops and forced cooling is not necessary.

When using a fan to cool machinery, dust may accumulate inside the machinery after long periods of operation. Depending on the parts involved, this could cause a malfunction. These filters prevent dust from entering the device, keeping the air inside the machinery dust free.

Fans are used to cool or ventilate electronic devices that may generate electromagnetic waves. These waves can escape from the fan cooling holes, causing interference to computers and measuring instruments. The screens allow the passage of air but block electromagnetic waves.
The screen is a durable magnetic shield using a stainless mesh fixed to an aluminum frame. Screens are easily attached to the fan using screws.
