ULVAC DAU-20 High Vacuum Diaphragm Dry Vacuum Pump
The ULVAC DAU-20 is a three-stage diaphragm dry vacuum pump designed for laboratory and industrial applications requiring high vacuum performance. Thanks to its enhanced compression ratio compared to standard diaphragm pumps, it can achieve an ultimate pressure of 200 Pa, making it an ideal backing pump for turbomolecular pumps (TMP).
Its completely oil-free (dry) design ensures that no oil comes into contact with the process gas, eliminating the risk of contamination. The three-stage diaphragm mechanism enables a significantly lower ultimate pressure than conventional single-stage and two-stage diaphragm pumps, providing outstanding performance in analytical instruments and precision vacuum systems.
The DAU-20 can be started directly from atmospheric pressure. Equipped with a built-in automatic resettable thermal protection system, a compact housing, and a simple mechanical design for easy maintenance, it offers a reliable and long-lasting vacuum solution for laboratories, research institutes, and OEM manufacturers.
