VACUUM EXTERNAL VACUUM GENERATOR CONTROLLER VACUUM PAD VACUUM ACCESSORIES Complex vacuum generator best suitable for control large flow Vacuum Generator ● Bestsuitabletocontrollargeflowwithwidthof31.5mm. ● 3typesofstandardizednozzle;Singlenozzle,Two-stagenozzleandTwinnozzle. ● Thetwin-nozzletypeisthemostdurableunitforapplicationswithlongersuctioningortransportationtime. The large-bore nozzle controls vacuum generation from start up to a prescribed reference preset pressure level, after which the small-bore nozzle takes over for maintaining a vacuum level. This combination makes possible substantial reductions in air consumption. Only one signal is used for vacuum generation as with previous models.
