This high static pressure airflow is very useful in various industrial and commercial applications, such as supplying air to high pressure cylinders, pushing gas through pipe systems, increasing oxygen supply during combustion, etc. The working principle of the high pressure air blower is based on the principle of centrifugal fan. When the motor drives the impeller to rotate, the blades on the impeller suck air from the inlet end and compress it at the center of the impeller. Due to the centrifugal force, the gas is accelerated and thrown out from the edge of the impeller, forming a high-speed airflow.
