Select from Purpose
Reducing the Number of Maintenance Services
Properly Cooling High-Density Packaging Equipment
Detecting a Fan Abnormality
Agenda
- Fan cooling function had deteriorated before being noticed.
- How do I prevent damage to precision equipment caused by heat generated?
Example) Data center
Advantages of Fan With Alarm
Alarm output from the fan helps prevent equipment issues and failures in the event of an emergency.
Choose between 2 alarm product lines.
Notification When Fan Stops
Alarm signal outputs when fan rotation stops. Stops due to abnormalities can be quickly detected, allowing for the problem fan to be replaced.
Notification When Fan Rotation Has Deteriorated
An alarm signal is output when the rotation speed of the fan deteriorates due to ingress of foreign particles, etc.
Contributes to predictive maintenance of equipment issues by allowing fan to be replaced prior to heat damage to equipment.
Even in multi-fan installations, just fans with a deteriorated cooling capacity can be replaced.
Reducing the Number of Maintenance Services
Agenda
- Reducing the number of maintenance services as much as possible
- Equipment must be installed where maintenance is difficult.
Example) Base station
Advantages of Long Life Fan
With an expected life of up to 180,000 hours, providing not only cooling performance but also a tough long life performance capable of withstanding continuous duty for about 20 years. It contributes to lower equipment maintenance costs and overall costs.
- Expected life varies depending on product. Check product page for details.
Lower Maintenance Costs and Overall Costs
Long life fan significantly reduces the number of fan replacements compared to S Type, reducing total costs.
Lifetime Comparison Example
- *Estimated life is 40,000 hours at an ambient temperature of 60 °C. The estimated life is an estimated value calculated using the formula for the life of the bearing grease. The estimated life varies depending on the product.
[Expected Life]
This indicates that 90 % min. of the total number of fans satisfy the following criteria when an acceleration test is conducted at an operating ambient temperature of 60 °C.
Criteria:
Rotation Speed (at rated voltage): 70 % min. of rated value
Input Current (at rated voltage): 130 % max. of rated value
Ideal equipment for where high reliability is required.
Since it is a long life fan that is not prone to failure, it is suitable for systems and equipment that have a significant ripple effect should a failure occur, and for applications that require continuous operation.
[Example applications]
- Backup Equipment for Blackouts
- Various Equipment Installed at Locations Such as Data Centers
- Continuous Operation of Plant Equipment
Stall Alarm
Alarm signal outputs when fan rotation stops.
Properly Cooling High-Density Packaging Equipment
Agenda
- Increasing the cooling efficiency
- The number of devices in the control cabinet has increased, and the pressure loss has increased
Example) Control cabinet for high-density packaging
Recommended product
Large fan
- φ172mm-51mm thick
- □140mm-51mm thick
Advantages of Large Fan
When pressure loss inside equipment is large, using a large fan is more effective in saving energy and wiring than using several small fans.
For high-speed specifications, the air flow and static pressure are increased without changing the frame size (S type)
The S type is available in "standard speed specification" and "high-speed specification" with up to twice the air flow.
Even when the number of devices in the control cabinet increases and the pressure loss becomes large, the air flow and static pressure can be increased without changing the fan frame size, by replacing it with a high-speed specification.

Easy Setup and Arrangement With the Accessory Set
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.
Other Accessories (Single unit)
Finger Guard/
Stainless Steel Finger Guards
Prevents fingers and other foreign particles from entering the rotating surface of fan.
Blocks air-borne dust, and keeps the air inside equipment clean
