What is the difference between H-type and L-type vacuum generators?
H = High vacuum L = High suction rate (large flow) An H-type is optimised for creating high vacuums > -0.4 bar. They are suitable for use in all standard applications. An L-type is optimised for generating a high suction rate at a moderate vacuum level up to -0.4 bar. They are can be used to great advantage with porous workpieces. The increased suction rate can deal better with leakages.
