Cooling Fans – EC Fans EMU Series

Power Consumption Reduced by Approximately 68 %^*1

By using brushless motors, power consumption is reduced by approximately 68 %^*1.

Expected Life^*2 60,000 Hours (Approx. 6 years)

By increasing the lifetime by approximately 2.2 times^*1, the number of fan replacements due to expected lifetime can be reduced, thus reducing maintenance costs.

Support Single-Phase 100-240 VAC (50/60 Hz)

Regardless of the country or region where it is used, a single unit can handle it. The same characteristics can be achieved regardless of the frequency used.

Approximately 45 %^*1 Lighter Mass in Weight

By using resin as the material for the frame, the mass is reduced to 0.29 kg (EMU1238).

No Grounding Required

No grounding is required due to the double insulation structure.

Fan With Low-Speed Alarm Improves Equipment ReliabilityPredictive Maintenance

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.

Mounting screws, filters, and other components have been installed to finger guards to prevent fingers and foreign particles from getting inside and to the panels which provide ideal ventilating and cooling for the control cabinet.
Since this is a set, there is no need to order individual components, and you can mount it to the fan and use it immediately after arrival.

• *The sets are sold separately from the fan.
