Construction of Centrifugal Blower
Centrifugal Blowers move air by means of centrifugal force generated by a rotating cylindrical impeller. Used for applications where increased air pressure, increased static pressure or high airflow is required. Centrifugal Blowers have a small outlet, which concerntrates air in a single direction and are therefore suitable for local cooling.
Centrifugal blower provide concerntrated airflow in a single direction suitable for forced cooling or heating
