Advantages of Variable Speed Axial Flow Fan
- I want to change the air flow as necessary
- I want to ship to a region where power supply frequency differs
- I want to suppress fan noise
- I want to reduce costs
We can solve such on-site problems with a speed control axial flow fan!
3 Reasons to Choose a Variable Speed Fan
Reason 1: Air Flow Can be Adjusted to Suit the Situation
Air flow can be matched to the equipment operating conditions and temperature.
For example, it is possible to build a system that operates at a set speed under normal conditions, but switches to high-speed operation when an abnormality occurs, such as "the temperature inside the equipment exceeds the setting temperature."
It is also possible to manually change the air flow to an appropriate level even if equipment conditions changes.
Reason 2: Air Flow Can be Adjusted Regardless of Where It Locates Anywhere in Japan and in the World, Even After Purchase
If power supply frequency changes, the air flow of the fan will also change.
The air flow can be adjusted to suit the shipping destination by adjusting the variable speed fan.
The same level of cooling can be achieved anywhere in the world, regardless of whether in a 50 Hz or 60 Hz region.
Reason 3: Noise Reduction, Power Saving, and Even Longer Life
By adjusting the air flow according to the situation, it is possible to reduce noise and save power.
This also helps to reduce bearing deterioration and extend the life of the fan.
How is It Used? 2 Adjustment Methods You Can Use
-
Manual Air Flow Adjustment
Air flow can be easily adjusted manually.
-
Automatic Air Flow Adjustment
Automatically controls the air flow of the fan according to the operating conditions and temperature.
Important Point MRS/MRE Series (Three-phase power supply input type) Can be Combined With Inverter
Combination With an Inverter is Possible
Oriental Motor has prepared the "air flow - static pressure characteristics" and "inverter parameter setting values" when combined with common inverters for your reference. (The graph on the right is 1 example.)
On product details page of this website, you can see the combination characteristics data for each product name.
Preventing Electric Corrosion
Electric corrosion is a phenomenon in which a bearing is damaged by an inductive current flowing through the bearing due to high frequency noise generated by an inverter, etc. This is a factor that shortens the life of the fan.
The MRS/MRE Series three-phase power supply input type uses ceramic ball bearings as a preventive measure against this problem. (Right figure)
Use as an "anti-electric corrosion fan" with confidence.

Important Point With the EMR Series, You Can Check the Operating Status of the Fan at a Glance.
The alarm output function is activated when the rotation speed drops due to unexpected conditions such as the cooling fan reaching the end of its service life or intrusion of foreign particles.
The fan can be replaced before it stops completely, contributing to efficient operation.
Important Point Easy to Control Air Flow.
The MD Series V type (speed control) can be combined with fan speed controller FSC-24 to allow for intuitive speed control by simply turning a setting dial. (Eliminates the need to design for a PWM control circuit. Also, multiple fans can be controlled by 1 unit.)
In addition, when used in combination with the thermostat, the 2 speeds can be switched automatically.
