Accessories There are a range of accessories available with the GXS to suit a variety of applications. These provide reduced engineering and systemisation resulting in low cost of ownership. All accessories are fully integrated with GXS to provide an efficient and safe system. Inlet and exhaust accessories Inlet and exhaust accessories have been especially designed to match the pumping capacities of the GXS range and optimise performance. • Foreline spool adapters for mounting instrumentation • Fully integrated Inlet isolation valves • Inlet filter housing with polyester or stainless steel elements...

Inlet Vacuum Filters The GXS range of pumps all have excellent powder handling capabilities and under fault conditions they will succeed where other dry pumps fail. However dry vacuum pumps aren't designed to continuously pump solid material so on certain applications an inlet filter would dramatically extend the time between services.
