Vacuum Blowers The blades (A) transport, accelerate and compress the air on the momentum principle. The air is dragged by the blades in this case. A vacuum is created...

Vacuum Pumps Vacuum pumps include an eccentrically mounted impeller with lamellas (A) which are pressed against the walls of the housing by centrifugal force and thus provide a seal....

Vacuum System and its Components Vacuum systems are used as grippers in automated applications. Customers benefit from the comprehensive component program of Schmalz, the vacuum specialist, when designing a...

Measurement Units of Vacuum Data The units pascal [Pa], kilopascal [kPa], bar [bar] and millibar [mbar] are most widely used in vacuum technology as units for pressure. The units...

The Coanda Principle Operating principle Pneumatic operation with integrated vacuum generation With the Coanda principle, compressed air is guided through an annular gap which accelerates it The increase in...

Bernoulli’s Principle Bernoulli’s Principle Pneumatic operation with integrated vacuum generation Compressed air escapes through holes in the suction cup and is greatly accelerated when doing so Due to the...

Venturi principle Operating principle Pneumatic vacuum generators function based on the Venturi principle Compressed air is introduced into the ejector (A) Due to the reduced cross-section of the motive...

Energy Required for Vacuum Generation The energy required for vacuum generation increases disproportionately to the attained vacuum. Increasing the vacuum from -600 mbar to -900 mbar, for example, increases...

The Atmosphere and its Effects on Vacuum Technology The air pressure (ambient pressure) depends on the elevation of the location as well as the temperature at that site. As...

Definition of Vacuum Vacuum is the term for air pressures which lie below normal atmospheric pressure. The ambient pressure is 1.013 mbar at sea level and decreases with elevation....
