VACUUMGENERATORS Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice 28 Single stage vacuum generators Single stage generators, robust reliable and compact suitable for applicationswhichneed the required degree of vacuum to be reached quickly with high flow rates. Performance and application The single stage vacuum generator operates using the Venturi principle. By feeding compressed air into port 1 of the generator, a depression (Vacuum) is generated at port 2 with the air being drawn from port 2 discharged out at port 3. When the compressed supply to port 1 is interrupted, the suction (Vacuum) at port 2 is lost. The optimum inlet pressure is different for each type of single stage generator which ranges from 1 - 6 bar. These generator are generally used in conjunction with suction cups for gripping and the handling of porous and non-porous objects with limited suction flow required. Adjustable version Based on the Venturi principle, these differ from traditional ones, infact they have an ejector with a much larger diameter, and are adjustable. This feature makes possible to change the device’s flow rate and degree of vacuum without affecting the inlet pressure. 2 1 3 Rotate/turn G1 (Vacuum) G2 (Supply) G3 (Exhaust) Vacuum technology Catalogue Single stage vacuum generators Series 1900
