How Does a Blower Work?

One of the most important components of a blower is the blower wheel. It passes fresh air through the ducts. It improves the airflow around coolant tubes to expedite the cooling process. If the airflow is not proper around the tubes, the air will not be cooled properly. This can happen if you do not maintain your aircon well. 

Different Choices of Blowers

Blowers are available in the market in different sizes and shapes.  The right choice for your machine depends on the specifications of the machine itself. Some of the most common types of AC blowers are:

  •         Propeller fan
  •         Centrifugal fan
  •         Vane-axial fan
  •         Tube-axial fan
