The Vortex Blower Operating Principle
Vortex blowers generate high-pressure airflow during each rotation of a unique one-sided, single-stage impeller. The impeller has 30 to 50 vanes that create discrete air pockets. Air entering these pockets is accelerated in two directions, axially and outward (radially). Air entering the outer casing’s annular chamber is redirected into successive pockets of the spinning impeller. This airflow cycle forms a vortex or stretched spring pattern (see diagram).
Velocity energy is increased or regenerated many times as air moves between the blower inlet and discharge.
Competitive designs
Other regenerative blowers have a double-sided or “paddle wheel” impeller. This design, with its twin vortices, is characterized by higher noise levels as the vortices are created at the inlet and merged at the discharge. These blowers have two seal gaps between the housing and impeller, complicating tolerances during operation at high ambient temperatures.
