Rotary vane vacuum pumps are primarily used in applications demanding a high level of the final vacuum with a large volume flow at the same time. Areas of application are, for example, vacuum supply for centralised vacuum systems or for handling sealed work-pieces.
Their performance range: Final vacuum up to ~ - 999.5 mbar, volume flow ~ 2 m3/hr. up to about 300 m3/h.
Side channel blowers offer a very high volume flow with a low to medium level of vacuum: Performance range: Final vacuum up to ~ -300 bar, volume flow up to 310 m3/h.
Their application areas: Handling of porous products or products having a high degree of leakage, pneumatic extraction or evacuation of particles that are not too coarse or abrasive, for example, extraction of wood dust in the timber processing industry
Ejectors provide a high level of final vacuum (~ -900 mbar) with low to medium volume flows at the same time (10 l/min. up to around 800 l/min.). They can be mounted directly in the suction line or on the vacuum cups.
Their application areas: targeted vacuum supply directly at the material to be handled, e.g. supply to vacuum cup units in a packaging machine. They represent an economic alternative to vacuum pumps, particularly for smaller quantities of suctioned air. Over and above this, FIPA ejectors are practically maintenance-free.
