What is the difference between an industrial fan and blower?
An industrial fan and blower are similar in that their purpose is to circulate air. In fact, a blower uses a fan as part of its assembly.
The fundamental difference between industrial fans and blowers is that an industrial fan uses blades to create a continuous flow and circulate the air in every direction. A blower on the other hand uses its impellers to direct air flow in one specific direction.
Industrial fans move large amounts of air at low pressure, with a specific pressure ratio of 1:1. With a pressure ratio of 1:1 to 1:2, blowers can move large volumes of air at a moderate pressure setting, using centrifugal force to blow the air out.
Finally, although industrial fans consume less power, and are therefore more energy efficient, blowers typically produce more airflow than industrial fans.
