Integrated Vacuum Trap LI-400 for Enhanced Diffusion Pump Performance

Integrated flangeless LI-400 trap is installed inside the diffusion pump instead of the standard oil deflector, without increasing the overall dimensions of the diffusion pump.

LI-400 trap performs the function of an oil deflector, is installed instead of a standard oil deflector in pumps, has an additional number of cooled screens for trapping vapours of oil return flow (more than the MU trap), covers the entire area of the inlet high-vacuum flange.
