These rechargeable in-line traps effectively block oil from backstreaming into mechanical pumps. Any mechanically pumped system, even one with a turbo pump, should have a foreline trap. The trap is positioned in the foreline between the roughing pump and the diffusion or turbo pump. It uses a disposable, absorbent, oxygen-free copper maze which requires no liquid nitrogen and will not hold water. Typically the maze is replaced every year. The seamless body is available in Aluminum. Features include:

• a quick change clamp for replacement of maze
• an O-ring end cap
• a recessed screen
• available in five pipe diameters

Larger sizes, special flanges and replacement parts for all traps are available by special order. Call for details.

Replacement elements also available.
