ULVAC RDA Series Multi-Stage Roots Dry Vacuum Pump
The ULVAC RDA Series is an oil-free (dry) multi-stage Roots vacuum pump designed for continuous operation from atmospheric pressure down to high vacuum levels. Its compact design, low maintenance requirements, and excellent water vapor tolerance make it an ideal solution for analytical instruments, helium leak detectors, semiconductor manufacturing processes, and backing applications for turbomolecular pumps.
The pump features a contact-free rotor design with no wear parts inside the pumping chamber, ensuring a long service life. Its oil-free compression mechanism eliminates the risk of process contamination. Thanks to its air-cooled design, which requires no cooling water, and its electronic control system supporting both single-phase and three-phase power supplies, the RDA Series can be easily integrated into a wide range of industrial applications.
