When used in line with a rotary vane or diffusion
pumps, complete trapping of water vapor, solvents and other condensable
gases is achieved, as well as a lower base vacuum.
These traps have also been used on diffusion pumping systems to
minimize oil vapor migration from the roughing pump to the diffusion pump.
The primary use though, is as a fore line trap for getting
condensable vapors out of the gas stream so they do not enter the vacuum
pump and degrade the fore line pressure of the pump through contamination.
They are a pretty good size for this style of trap and can be considered
when larger roughing pumps are engaged in the evacuation process.
It is important when using these traps to maintain
the level of the liquid nitrogen at the correct level in the trap.
HyVac’s traps come with a number of nice features.
Quick release clamp allows for easy disassembly of the 2-piece trap
body. A demountable liquid
nitrogen reservoir included for easy cleaning.
The traps provide roughly 6-8 hours of operation.
