Vortex fan is a kind of high voltage fan, also called ring fan. The impeller of the vortex fan is composed of dozens of blades, which is similar to the impeller of a huge gas turbine. The air in the middle of the impeller blade is subjected by centrifugal force and moves toward the edge of the impeller, where the air enters the pump chamber and circulates in the same way from the starting point of the blade. The circulating airflow generated by the rotation of the impeller leaves the air pump with extremely high energy for use. The vortex gas pump uses a special motor, compact structure, small volume, light weight, low noise, to send out the air source without water without oil.
