These rechargeable in-line traps effectively block oil from backstreaming into mechanical pumps. Any mechanically pumped system, even one with a turbopump, 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 that 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 the maze
an O-ring end cap
a recessed screen
available in 3 pipe diameters
Larger sizes, special flanges, and replacement parts for all traps are available by special order. Call 301-975-9798 for assistance.
