Axial Fans

Axial fans use a propeller to generate airflow in the direction of the axis of rotation. Capable of generating a large air flow, axial fans are suited for applications requiring ventilation cooling.

Axial Fans

Long Life Axial Fans

These axial fans have an expected life of 100,000 hours (about 11 years). They reduce the increase in bearing temperature, inhibit grease deterioration and improve vibration resistance and shock resistance through bearing enlargement. They also increase the life of circuits and couplers and reduce failure rate. They are designed based on the concept of initial failure so that random failure and wear-out failure will not occur, allowing for 100,000 hours of continuous operation or more (survival rate of 90% or higher).

Long-life axial fans have an expected life of 100,000 hours, so the number of cooling fans that need replacing is decreased compared to conventional models.

Long Life Fans

*1 - The conventional models are T-MRS16-BTA-G and MRS16-BTA. The long-life fan is MRE16-BBHG.

*2 - Estimated life of 35000 hours with an ambient temperature of 60°C (140°F). Estimated life is an estimated value calculated using the bearing life-of-grease formula. Estimated life is different for each model.

Device Ventilation and Cooling

The large airflow of axial fans is suitable for ventilation and cooling inside electronic devices.

Ventilation

Low Speed Alarm Types

An alarm is output when the fan speed drops due to the service life of the fan or ingress of foreign objects. This makes it possible to order and replace the fan with a new one before it stops.

If multiple cooling fans are being used, it is possible to only replace the cooling fan with decreased cooling capacity. Even if the cooling capacity of the fan decreases, the effect on the equipment can be minimized.

Low Speed Alarm

Ideal for Hard to Service Environments

Cell Site

· Equipment that is continuously operational and cannot be stopped
· Areas that are hard to enter
· Equipment that is delivered to and installed in remote locations

 

Thermostat Available for Energy Saving

ThermostatThermostats (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.

System Configuration

Finger Guard

Finger Guard

Finger guards prevent fingers or foreign objects from entering the fan. Finger guards are mounted to the fan frame using bolts.

MRE16 FG16D
MRE18 FG18D
MRE20 FG20D

Filter

Filter

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.

Thermostat

Thermostat

Thermostats automatically perform ON/OFF fan control in accordance with the temperature fluctuation inside the equipment. It helps improve the equipment's "environmental" performance relative to energy savings, noise reduction, etc.
