Foreline vapour traps are design to protect vacuum systems from oil contamination as a result of back streaming once the rotary pump has reached the molecular flow pressure range.
|HV & UHV Traps|
HV & UHV Traps are fitted between the system and the high pumping group.
These traps serve two purposes:
They prevent vapour backstreaming and also help to produce a lower system ultimate vacuum as a result of cryogenic pumping.
