Historically, AC blower is usually cheaper than DC blower. However, today's price difference is negligible, which means that when making a purchase decision, you need to carefully weigh the advantages and disadvantages of each fan.
DC technology has become increasingly complex in recent years and can now be used in residential and industrial ceiling fans. The DC fan has a motor that relies on a permanent built-in magnet to attract and remove the rotor on the shaft connected to the inverter. DC technology is more fresh than the exchange technology, which means that there are fewer options. As the DC fan of the electromagnetic interference is minimal, sensitive electronic devices often use DC fans to prevent electromagnetic interference. For example, computer applications and devices rely on DC fans because they prevent overheating while minimizing electromagnetic interference that may have a negative impact on sensitive applications.
DC blower is widely considered to be the most effective fans. They consume less power than AC blowers. In fact, DC blowers consume 70% less energy to produce the same amount of output as other fan types. For example, this means that a 25-watt DC drive blower uses the same power as the 100-watt AC drive drive. This is ideal for business facilities such as restaurants so that you can let the fans fly all day without generating astronomical electricity.
DC blower uses a new type of electric commutation motor (ECM). These motors are not only extremely efficient, but also very quiet. Because they are quiet, DC blower is a good choice for applications such as medical instruments, telecom switches, or car entertainment systems, and noise can be annoying. DC fans typically use less voltage than AC fans. Most DC fans are low pressure fans. For example, you can usually find 5V, 12V and 24V versions of DC fans. Larger models of DC fans, such as 119mm to 172mm fan models, are typically available for 48V. In contrast, most AC cooling fan models can provide 115V, much higher voltage. The lower voltage also reduces the risk of DC blowers.
