Foreline
Traps
These rechargeable in-line traps effectively block oil backstreaming from mechanical pumps. Any mechanically pumped system, even one with a turbo pump, should have a foreline traps. The trap is placed in the foreline between the roughing pump and the diffusion or turbo pump. It uses a disposable, oxygen-free copper maze absorbent which requires no liquid nitrogen and will not hold water. Typically the maze is replaced every 1-2 years. The seamless body is available in aluminum.
- A quick change clamp for replacement of maze
- A viton “O” ring end cap
- A recessed screen
- Available in five pipe diameters
Replacement elements (Copper Maze) also available.

Vacuum
Monitor
This vacuum monitor allows you to monitor the vacuum level in the foreline between the roughing pump and the diffusion (or turbo) pump. A high value would indicate a leak in the system or possibly an inefficient roughing pump. Comprised of a thermocouple gauge control module and cable. The unit can mount directly to the Foreline Trap via a thermocouple (TC) port supplied at no charge when ordered with a Foreline Trap. The 3-station version of the Vacuum Monitor allows the vacuum levels of several pumps to be measured.
