Vmeca's pumps are based on "multi-stage" ejectors that are vacuum generation by supplying compressed air through a series of nozzles.
This provides a very effective difference between added air flow and achieved vacuum flow, and is up to 70% more energy efficient than rotary vacuum pumps.
Vmeca's program covers most needs. From "Micro" to "Mega" and from "simple" to full-rigged version with integrated valves and digital pressure sensors.
