High reliability: generous lubrication of moving parts.
Safe process and systems: fast acting inlet valve for best in class anti‑suck back protection.
Configured to meet your vacuum needs: mode selector and two position gas ballast.
No unplanned downtime: designed for easy maintenance.
Better work environment: quiet running and intrusive frequencies minimised.
Two position gas ballast: allows either 60 g/hr or a class leading 290 g/hr of water vapour to be handled.
Universal motor: to cover the widest possible voltage and frequency range from a single variant.
Smooth controlled inlet valve: opening by oil pressure to eliminate pressure surges.
Rapid closing inlet valve: within 0.4 seconds of pump stopping.

1. Huge final vacuum pressure, capable of high pumping speed and superior steam handling.
2. It is quiet during operation.
