COMBI RH 3704 L is a vacuum pump unit combining a HiLobe 4504 vacuum booster and a COBRA NX 0650 A backing pump, designed for high pumping speed and low ultimate pressure in industrial vacuum applications. It achieves a pumping speed of 3668 m³/h at 1 hPa with an ultimate pressure of 1 × 10⁻² hPa and a maximum power consumption of 18 kW, operating on 400 V AC (±10%), 50 Hz. The unit has a noise level of ≤80 dB(A) at 1 hPa, weighs approximately 1130 kg, and features a gas inlet of DN 160 ISO-F/PN 16 and outlet of DN 160 ISO-F/PN 16 / G 3". All models in the COMBI RH series share a maximum noise level of ≤80 dB(A), 400 V AC input, and integrated process monitoring for safety and uptime.
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
