Features

AM Series

● Low air supply pressure, reach max. vacuum level at 3.4 bar.
● Optional energy-saving system(ES) or other control device.
● Suitable for occasions requiring large vacuum flow.


AL Series
● High vacuum flow 
● Optional energy-saving system(ES) or other control device.
● Short evacuation time.


AH Series
● Especially for non-leakage and non-porous applications.
