Drystar GV400 & EH2600/4200 Packages Edwards has pioneered the use of dry vacuum pumps in some of the most critical and demanding applications. By combining the well proven Edwards claw mechanism pumps with a hydrokinetic drive booster; the Edwards Drystar GV400/EH2600 and GV400/EH4200 series provides benefits in economy, performance and compactness, with a clean robust pumping alternative to oil-sealed vacuum pumping systems. The Drystar systems non-contacting mechanism reduces wear and maintenance for higher up-time and provides for faster pump-down performance. The Drystar packages are effective and cost efficient, and offer the ability to handle dust and water vapour without the risk of process contamination, loss of performance and maintenance issues associated with oil-sealed vacuum pumping systems. Features and benefits • Reduced maintenance ͳͳ Eliminate regular oil changes, non-contacting mechanism eliminates wear ͳͳ Extended pump life on dusty applications - no dust build-up in oil, leading to high wear ͳͳ No need for pressure switching and bypass arrangements • Improved process ͳͳ No oil contamination of process - improved product quality ͳͳ Consistent vacuum performance - no water contamination of seal oil which reduces pump performance and extends pump down time ͳͳ Hydrokinetic drive booster gives faster pump down performance product datasheet • Added environmental and safety standards ͳͳ Eliminates exhaust oil mist, oil handling and disposal costs ͳͳ Reduces handling of contaminated pump oil, spillages and exhaust oil vapour around the pump area ͳͳ Reduced footprint for better space utilisation ͳͳ Global aftermarket support for improved uptime and support Vacuum scien
