The GRM1201 is a high-speed multi-stage roots dry vacuum pump delivering 1200 m³/h pumping speed with ultimate pressure of ≤0.15 Pa. Sharing the same compact platform as the GRM601 (865 * 344 * 751 mm, 260 kg) but with ISO160 inlet for higher throughput, it excels in PECVD, MOCVD and demanding semiconductor clean and medium process applications.
