Vacuum suction unit with emphasis on functions Fast and stable suction transport without positive pressure source Pressure sensor Vacuum filter PCD Silencer TotAirSys (Total Air) TotAirSys (Gamma) 3QR negative pressure switching unit Electrical response and pressure waveform Negative ON pressure Overshoot present Atmospheric pressure Vacuum release without positive pressure to prevent small chips from being blown away. Air blow-out 0!! * Small workpieces may be blown away Vacuum pressure Solenoid valve Ideal for suction transport of small articles! Solenoid valve Atmospheric pressure Vacuum pressure...

1 Vacuum burst 1 valve not required • Vacuum release without positive pressure to prevent small chips \ from being blown away. No further countermeasure required • No need for burdensome adjustment of burst pressure, flow rate and timing • Slimmer with no vacuum burst valve Speeds up the vacuum release in returning to positive pressure and shortens suction time with the use of solenoid valve with large flow rate Discrete chip tray 2 Footprint minimized • The footprint has been reduced by 44% and weight by 53% as compared with CKD's conventional unit with burst, making it ideal for downsizing...
