Regenerative Blowers - 14270 Regenerative Principle Blower Features and Benefits

The impeller blades passing the inlet port draw airor other gasses into the blower. The impeller blades then, by centrifugal action, accelerate the air out- ward and forward. Here the “regenerative” principle takes effect as the air is turned back by the annular shaped housing to the base of the following blades where it is again hurled outward. Each “regenera- tion” imparts more pressure to the air. When the air reaches the stripper section at the outlet (the strip- per is the part of the blower located between the inlet and the outlet in which the annulus is reduced in size to fit closely to the sides and tips of the impeller blades) the air is “stripped” from the impeller and diverted out of the blower. The pres- sures or vacuums generated by the one or two spinning, non-contacting, oil-free impellers are equal to those obtained by many larger multi-stage or positive displacement blowers.
