Axial
Flow Fans
Axial flow fans use a propeller to create a flow of
air in the direction of the axis of rotation. These fans create
a large airflow, making them optimal for use as ventilators
for overall cooling of internal machinery components. In the
ORIX fan line, axial flow fans are available in a wide variety
of sizes and voltage characteristics. |

Centrifugal
Blowers
Centrifugal blowers move air by means of the centrifugal
force generated by rotating a cylindrical runner on which blades
have been arranged. Centrifugal blowers have a small outlet,
which concentrates air in a single direction, and are therefore
suitable for local cooling. They also create large static pressure,
making them optimal for cooling equipment through which air
cannot flow easily and for airflow through ducts. |

Cross
Flow Fans
Cross flow fans create a wide flow of air using a long cylindrical-shaped
impeller. Air is drawn inn along the sides of the runner, flows
along the circumference of the runner, and is blown out laterally,
creating a uniform flow of air. Cross flow fans are used for
cooling circuit boards installed in equipment, air curtains,
and other applications. In addition, cross flow fans offer the
advantages of right-angle air flow and rectangular shape which
facilitates installation in corners and saves space. |

Thermostat
By detecting the ambient temperature, the thermostat turns the
fan on and off to maintain appropriate working temperatures.
The use of a thermostat is recommended for energy conservation
and noise reduction.

Overview
of Cooling Fans
A fan is a device
that creates airflow by using a motor to rotate blades. Cooling
fans are essential in the smooth operation of many sophisticated
machines, such as electronic equipment. The ORIX fan line includes
AC and DC axial
flow fans for ventilation and cooling, centrifugal
blowers for local cooling, and cross
flow fans for a wide, uniform sheet of air. The ORIX fan line
incorporates specially designed fan blades for increased air pressure,
increased static pressure, high airflow and low noise.
Advanced functions
are often needed to ensure equipment is cooled adequately, thereby
improving the reliability of the equipment itself. Temperature sensors
can detect changes in internal temperature and adjust airflow, and
alarms that can detect faults, are some of the functions offered
with ORIX fan products. In addition, accessories such as thermostats
are available for energy savings by only operating the fan when
needed.
