Drystar® GV80 Vacuum Pumps EDWARD Series

Drystar® GV80 Vacuum Pumps EDWARD Series

Drystar 80-EH500/Drystar 80/EH500 PFPE EDWARD Drystar80 is the most cost effective introduction to basic dry pumping. It is available as a stand-alone unit for 80 m3h-1 repeatable pumping performance; or in a combination with the respected EH500 hydrokinetic drive mechanical booster, offering 500 m3h-1 displacement for applications where increased pumping speed and/or lower vacuum levels are required. Depending upon the application the Drystar80 can be supplied with mineral oil or PFPE lubrication.
