Large Airflow AC Axial Fans - MRS Series

The MRS Series fans are large airflow, high static pressure and high-efficient AC input axial fans, available in frame sizes ranging from 6.30 in. to 9.84 in. (160 mm to 250 mm). Models are also available with built-in alarm circuits that can detect fan rotation abnormalities and respond by outputting alarm, allowing for service to be performed.

A Variable Flow model is also available in a frame size of 7.09 in. (180 mm) and features an internal power control device which allows adjustment of airflow to match the cooling requirements.

Single-Phase 110/115 VAC, Single-Phase 220/230 VAC or Three-Phase 200/230 VAC

Large Airflow Axial Fans

Cooling Densely Mounted Devices with One Fan

Effective cooling is possible using a large cooling fan offering high static pressure. Using one large axial fan is more efficient than using multiple small axial fans. they are also suitable for equipment with high blower, high duct air flow and high installation density.

High Static Pressure

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.

Thermostat Available for Energy Saving

Thermostats (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.

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.

Finger Guards

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

Filters

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.
