EMR Series
Power Consumption
Reduced by 132 kWh/year
CO2 Emissions
Reduced by 60 kg/year, approximately 30 %
Power Consumption Reduced by Up to 48 %*
By using brushless motors, power consumption is greatly reduced compared to conventional products, while having the same characteristics.
Furthermore, the brushless motor generates low heat, the heat generated by the fan drive circuit can be reduced.
In addition, the same characteristics can be achieved regardless of what frequency is used.

Fan With Low-Speed Alarm* Improves Equipment Reliability
The alarm output function is activated when the rotation speed drops due to unexpected circumstances such as end of service life of the cooling fan or by the ingress of foreign particles, etc.
This makes it possible to replace the fan before it comes to a complete stop.
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.
- *Products equipped with the low-speed alarm function are applicable to low-speed alarm types and variable speed types with low-speed alarms with a frame size of 180 mm and 200 mm.

Accessories
A variety of accessories are available for use in combination with fans.
