Edwards GXS range incorporates our unique screw technology with a world leading high efficiency drive to achieve excellent vacuum performance and low running costs. With advanced temperature control, low maintenance and long service intervals, the GXS is the most robust and economical vacuum pump that establishes a new standard in dry pumping.
Features and Benefits
Maintenance
- Low capital cost and minimal maintenance requirements lead to lowest cost of ownership.
- Extended periods between user intervention.
- Lower consumable costs.
Environmental
- No oil disposal.
- No oil emissions into atmosphere.
Performance
- Very stable pumping speed gives repeatability to processes.
- Continuous pumping at atmosphere.
- Ability to handle particulates.
- Dry eliminates back-streaming, thus protecting reactive alloys from contamination.
Safety
- Unobtrusive noise levels.
- No unsightly oil spills.
- No hazardous oil vapours.
