The capacity of power a system can hold, or the amount of
power flexibility it allows dictates the type of fan which can be
used. The difference in the cost between AC fan and DC fan is
negligible, therefore choosing the right fan according to its
functionality and performance. While AC fans provide a constant
flow, DC fans provides a variable, uneven flow. DC fans consume
lesser power, lower levels of Electro Magnetic Interference and
Radio Frequency Interference. DC fans and blowers provide a silent
operation and can be used in applications such as medical
instruments, telecom switches, car entertainment systems, etc.
When choosing fan for your applications, it is important to look at
the cooling requirements of the system and applications, the fan
type, the air flow, and AC or DC power operation.
