 Axial
Fans
With Axial fans,
the air enters and leaves the axial fans in the same axial direction.
Typically the air volume in these axial fans are relatively high (dependant upon the
frame, size and motor), and the pressure, measured in inches of
H2O is on the lower end of the scale. The greatest variety of size
and airflow performance is offered in axial fans (25mm - 172mm
with airflow of 2cfm - 350cfm).
 PC
cooling (PC fans), Electronic cooling, Component Cooling
PC cooling
(PC fans), electronic cooling, and component cooling fan motors
rotate fans to cool the inside of PCs and other office automation
(OA) equipment. The PC cooling
(PC fans), electronic cooling, and component cooling fan does this by directing heat outside. Minebea manufacture
high-end axial fans using ball bearings produced in-house.

 DC
Fans / AC Fans
Selecting between
DC Fans and AC Fans:
First,
consider whether you want DC fans or AC fans. In the past,
the higher cost of DC fans
led to the
almost exclusive use
of AC fans. Now that this price differential has disappeared,
the many advantages of DC fans make them the best choice. One advantage
of DC
fans is longer life. Another is almost 60% less power consumption
than AC fans.
According to industry experts, a 10°C increase in fan temperature
can reduce its life by as much as 20,000 hours.
Another selection
factor is that the speed of DC fans is directly proportional to
voltage, so it can run at the speed required for adequate cooling.
However, usually DC fans runs at less than maximum speed, creating
less noise, and using less power.

 Blowers
 Cross
Flow Blowers
Cross flow
blowers are unique in that they are designed for large surface
airflow needs as found in appliances or air curtains.
Air is circulated twice through the impeller blades
before exiting the fan. The cross flow blowers are more suitable
for high flow and low pressure applications.
 Centrifugal
Blowers
Centrifugal
blowers require a scroll to enclose the impeller
to generate pressure. Air enters axially and is exited
radially while
being directed at a focused right angle for spot cooling.
Centrifugal blowers generally have a low airflow and high
pressure. Efficiency is lower than that of axial fans and
the impeller is typically smaller as well. Noise concerns
must be taken into account when considering these
fans as they have much higher dBA levels.
