Most standard centrifugal type blowers impart energy to incoming air by simply hurling it outward from a central point. And operate on a regenerative principle that provides much higher pressure and vacuum. In these devices, air enters through an inlet port and is accelerated by the impeller. Through centrifugal force, this air is thrown against the walls of casing where it is reflected back to the base of the impeller blades. The process is repeated many times during each revolution of impeller and constantly compounds the energy and acceleration imparted to incoming air. The overall effect is not unlike that obtained in multi-stage devices. However , in the case of the centrifugal blower, the increased output is due to many regenerative cycles that take place during each revolution of the impeller . To meet specific requirements, many combinations of these blowers are possible.
The VFC Series are single-stage ring compressors with a maximum pressure of 139 in. H2O, a maximum vacuum of 110 in. H2O and a maximum capacity of 570 SCFM. Motors are direct drive from 1/10 to 10HP. Voltages are available in 240V single phase, 3-phase 220-415V dependent upon motor size. All units are provided with threaded flanges.
