Use with 2" Body Traps

  • Easy exchange of cartridges
  • Metal sieve units are reusable

Two-piece coaxial foreline traps offer a wide selection of replaceable filter element materials. Filter elements for a two-piece trap are removable stainless steel screen cartridges filled with copper, stainless steel or bronze wools, activated alumina, activated carbon or dual element absorbent material.

Metal wool filter elements are used primarily for the trapping of pump oil backstreaming through a vacuum system. During pump operation, oil coalesces on the metal wool element and drains back to the vacuum pump. Activated alumina effectively absorbs both acids and water vapor while activated carbon adsorbs organics and water vapor. The selection chart at the bottom of the facing page will help in choosing a filter element for your specific application.

Filter cartridges are quickly and easily replaced by removing the banded clamp that fastens a two-piece coaxial trap body. To minimize down time, MDC recommends keeping spare filter elements on-hand for quick replacement. Reusable elements may be cleaned and stored for the next exchange. With the exception of the activated carbon and dual element filters, all others are reusable. Filter elements are not included with trap assemblies and must be ordered separately using the part numbers detailed on the next page. Filters for 2", 4", 6" and 8" body diameters are included. Contaminated elements may be cleaned with a solvent and allowed to dry before reusing.
