Regenerative blowers use an electric motor to rotate multiple vane impellers inside their chamber. The rotational force pushes and compresses the air as it enters through the inlet. The procedure keeps going as the blower continuously draws in more air, compressing it and forcing it to the outer edges of its impellers. The air that has been fully compressed is then gathered and sent to the outlet.
Regenerative blowers function similarly to the two blower types mentioned above, but because of their extremely tight tolerance, they behave like positive displacement blowers in that the majority of the gas is forced through by internal slip (clearances), and they also use the impeller’s velocity to provide pressure, just like centrifugal blowers do. This blower’s typical flow rate, vacuum, and pressure range are up to 1500 CFM, 20″HG vacuum, or 15 PSI at its highest.
