・Compatible with ejector systems and vacuum pump systems ・Energy saving ejector Air supply is cut-off when vacuum is reached. Air consumption: 93% reduction (Under SMC’s measurement conditions) ・More efficient ejector: Suction flow increased by 50% (Compared to other SMC 1-stage ejectors) ・Energy saving efficiency: 93% reduction ・Improved low noise and suction flow by adoption of a high-noise reduction silencer ・Supply valve: N.O. specification: ZK2mA-X188: Single Unit, ZK2mA-X211: For Manifold
