CASE SIZE
Square axial fans come in standard sizes set by the industry. They are commonly quoted
with millimeters in the format length times height times width. A case size measuring 120
mm tall,120 mm long, and 38 mm wide may be quoted as 120 x 120 x 38 mm.
CURRENT AND VOLTAGE
Fans designed to be powered by alternating current are known as AC fans. They are
available in two voltage ranges, 100 to 125V, and 200 to 240V. A fan rated between 100 to
125V can be powered by household outlets in the US, which run at around 120V AC.
CONNECTORS
AC fans usually have terminal or wires as its power connector, located on the edge of its
case. Terminals are two metal prongs which can be attached to a cord such as a power
plug. Wire connectors, also known as leads are directly wired to the power source.
SPEED
Some applications demand a high airflow while others require minimal noise. To meet
these requirements, fans are available in different speeds rated in RPM or rotations per
minute. Given the same fan size, a higher RPM is correlated with higher airflow and noise.
BEARINGS
Axial fans are available with different types of bearings that can affect its life expectancy
and mounting position. Dual ball bearings have the longest life and allows the fan to be
mounted in any direction. Sleeve bearings have a low cost but a short life expectancy.
