Optimum vacuum control All GV 630-4800 vacuum pumps are fitted with a modulating vacuum control valve at the pump inlet as standard. An additional vacuum control device is therefore unnecessary, unless the vacuum levels at particular points of use need to be varied. Many other common vacuum technologies utilize ‘air bleed’ to control vacuum level with the additional function of maintaining mechanical integrity in low flow conditions. This is not necessary with Atlas Copco’s screw technology, leading to optimum energy savings. MODULATING VALVE FITTED DIRECTLY TO PUMP INLET The valve’s...

Oil cooler 8. Oil pump 9. Vent Working principle As the rotors turn, air is drawn into the rotor housing through the inlet port. Air is then trapped as the inlet port is closed off. As rotation continues, the air is conveyed to the discharge side and forced out of the discharge port. Oil is present within the twin screw stage to lubricate, seal Inlet port and cool the wetted parts. This oil is...
