Foreline vapour traps are designed to protect vacuum systems from oil contamination once the rotary pump has reached molecular flow pressure range, known as back streaming.
The copper and stainless steel wools in an ambient trap prevent direct line of site from the inlet to the outlet. A high capacity of oil vapour can be contained due to the copper and stainless wools highly absorbent properties.
Replacement copper and stainless wools inexpensive and easily replaced once maximum saturation of oil vapours has been reached.
