■Advantages of fans with alarms
Alarm output from the fan helps prevent equipment problems and failures in the event of an emergency. You can choose from two alarm types.
■Notification when the fan stops
Outputs an alarm signal when the fan stops rotating. Abnormal stoppage can be detected immediately and the affected fan can be replaced.
■Notification when fan speed decreases
If the rotation speed of the fan decreases due to contamination with foreign matter, an alarm signal will be output. Fans can be replaced before they cause thermal damage to the equipment, contributing to predictive maintenance of equipment troubles. Even when multiple fans are installed, you can only replace the fan whose cooling capacity has decreased.
■Advantages of long-life fans
With an expected lifespan of up to 180,000 hours, it exhibits not only excellent cooling performance but also tough long-life performance that can withstand continuous use for approximately 20 years. Contributes to equipment maintenance and total cost reduction. Expected lifespan varies depending on the product. Please check the product page for details.
■For equipment maintenance and total cost reduction
The long-life fan significantly reduces the number of fan replacements compared to the S type, leading to a reduction in total costs.
■Expected lifespan
We conducted an accelerated test to show that more than 90% of the fans meet the criteria below when the operating ambient temperature is 60°C.
Judgment criteria: Rotational speed (at rated voltage): 70% or more of rating Input current (at rated voltage): Within 130% of rating
■Ideal for equipment that requires high reliability
Because it is a long-life fan that is difficult to break down, it is suitable for systems and equipment where a failure would have a large impact, and for applications that require continuous operation.
[Application example]
・Backup device in case of power outage
・Various devices installed in data centers, etc.
・Continuously operating factory equipment
■Rotation stop alarm
Outputs an alarm signal when the fan stops rotating.
