The COMBI RH 1904 L is a vacuum pump unit combining a HiLobe 2104 vacuum booster and a COBRA NX 0950 A backing pump, designed for high pumping speed at low pressures. It achieves a pumping speed of 1925 m³/h at 1 hPa with an ultimate pressure of 1 × 10⁻² hPa and a maximum power consumption of 22 kW, operating on 400 V AC (±10%), 50 Hz. The noise level is ≤80 dB(A) at 1 hPa, and the unit weighs approximately 1270 kg. Gas inlet and outlet connections are DN 100 ISO-F/PN 16 and DN 100 ISO-K. The unit features integrated process monitoring and intelligent control through its booster interface.
Reliable: High uptime, increased safety thanks to process monitoring via integrated sensors, intelligent user interface of vacuum booster High performance: High pumping speed at low ultimate pressures, fast pump-down times, high energy efficiency Flexible: Various design options available, different combinations of backing pumps and vacuum boosters possible
