A combination of the patented double start scroll form technology and by-pass valves have enabled Edwards to offer the XDS35i Enhanced range of pumps to complement our original family.

XDS35i incorporates smart drive technology to look after the pump and provide worldwide performance.

With reduced peak power requirements at roughing pressures and continuous higher roughing speeds, these enhanced pumps enable the user to address the performance envelope to help with those special applications where roughing performance or the ability to evacuate a large chamber volume is important.

The enhanced versions offer up to 20% lower peak power requirements during initial pump down: meaning it has the ability to pump down large volume chambers with no loss of performance.

It has up to 25% more pumping speed at these roughing pressures, which helps on higher frequency cycling applications as well.
