Oil-free vacuum pump – HiScroll 18

  • High Safety:
    • The hermetically sealed HiScroll 18 vacuum pump features a check valve as a safety measure
    • A two-stage gas ballast valve ensures high water vapor tolerance and allows individual process adaptation of the pump
  • ATEX certification:
    • The pump is certified to ATEX II 3/-G Ex h IIC T4 Gc X +5° C ≤ Ta ≤ +40 °C as standard
    • It can be used with internal explosion protection of equipment category 3G for Ex zone 2 with gas types IIC (These versions are only available without the optional integrated pressure sensor)
  • Environmentally friendly:
    • The use of novel IPM (Interior Permanent Magnet) motor in the HiScroll pump allows its power consumption to be significantly reduced despite high pumping performance
  • Low noise level:
    • The pump is extremely quiet at <47 dB[A] (<42 dB[A] in stand-by mode)
    • It makes it ideal for use in quiet and highly integrated working environments, such as on mass spectrometers, in research institutes or leak detection systems
