Product Overview
The SMC ZL112A is a high-performance multistage vacuum ejector designed for precision vacuum generation in pneumatic industrial systems. Manufactured by SMC Corporation, a global leader in pneumatic control technology, this ejector utilizes a multi-stage nozzle and diffuser configuration to amplify vacuum flow while minimizing compressed air consumption. Unlike single-stage ejectors, the ZL112A achieves deeper vacuum levels and higher suction flow rates by cascading compressed air through successive expansion chambers. This unit serves as a critical vacuum source for pick-and-place operations, material handling, and packaging machinery, delivering reliable performance without the need for external vacuum pumps.
