Vacuum pumps/generators Medium
piCLASSIC Xi40-3
Patented COAX® technology inside – the most
energy efficient ejector technology
The Xi cartridge offers high flow at deep vacuum
levels to 95 -kPa.
Suitable for non-porous applications when deep
vacuum level is needed.
Large capacity range, available with 1 to 6
COAX® Xi40 three-stage cartridges. A smaller
piCLASSIC can easily be upgraded with more
capacity if needed.
Low-weight, configurable and modular design.
Easy disassembly for maintenance.
