• High pumping speed (15 m3/h, 250 L/min) and low ultimate pressure provide clean, dry vacuum
• Long-life tip seals generally only need to be replaced on a yearly basis
• Bearing purge port translates to simple maintenance and long bearing life
• Automatic air ballast manages water vapor without reducing pumping speed
