The idea for a venturi vacuum has existed in theory for nearly 300 years going back to physicists who studied how fluids work under pressure. Venturi vacuum generators create vacuums using a venturi chamber designed to move gases or fluids out of a region of space.

A multistage design generates a high vacuum flow with less air consumption than other air powered vacuum pumps. Venturi pumps depending on the design have the. Though most applications can use vacuum from either one of the sources one will clearly outweigh the other depending upon the design and application requirements from the point of view of cost space temperature etc. 4 0 out of 5 stars 2.
