inspection, replace the filter, etc. Injury may occur as a
result of touching the Fan blade.
Which has a better cooling effect, blowing air in or
blowing air out?
It depends on the location and number of heat-generating
elements.
What kind of precautions are there for building an
Axial Fan into equipment?
Always mount the optional Finger Guard when there is
any possibility that a person may touch the Fan blade.

How do you define the service life of an Axial Fan?
The service life of an Axial Fan is generally determined by
the bearings.
The following diagram is a simple, mechanical illustration
of the Fan structure.
The Fan blade will turn smoothly if the bearings are in
normal condition. When there is an abnormality in the
bearings, however, the friction between the shaft and the
bearings will increase until the blade eventually stops
turning.
This is the definition of a Fan's service life.
