Leybold TRIVAC D 4 B Dual-Stage Rotary Vane Vacuum Pump 5.8 m³/h 3~ Motor
The Leybold TRIVAC D 4 B is a compact, reliable dual-stage oil-sealed rotary vane vacuum pump perfect for laboratory and industrial medium vacuum applications. With a nominal pumping speed of 5.8 m³/h (3.4 CFM), ultimate partial pressure of 10^-4 mbar (0.75 x 10^-4 Torr), and water vapor tolerance of 30 mbar (22.5 Torr), it excels in freeze drying, rotary evaporation, Schlenk lines, vacuum ovens, and backing high-vacuum systems.
- Ultimate total pressure without gas ballast: < 2 x 10^-3 mbar (< 1.5 x 10^-3 Torr)
- Ultimate total pressure with gas ballast: < 5 x 10^-3 mbar (< 3.8 x 10^-3 Torr)
- Water vapor capacity: 110 g/h (0.243 lbs/h)
- Oil filling min/max: 0.3 / 0.8 L
- Noise level: 50 / 52 dB(A)
- Motor: 0.37 kW (0.5 HP), 3~ 50/60Hz, 1800 rpm
