In contrast to the single piece units on the previous two pages, the two-piece coaxial foreline traps offer a wider selection of 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. During operation, pump oil coalesces on the element and returns to the pump. Activated alumina effectively adsorbs acids and water vapor,while activated carbon adsorbs organics and water vapor. Filter cartridges are quickly and easily replaced by removing the banded clamp that fastens the two-piece body. MDC recommends keeping a spare element on-hand for a quick change to minimize down time. Reusable elements may be cleaned and ready for the next exchange. Note that filter elements are not included with trap assemblies and must be ordered separately. Two-piece traps are offered with 2", 4", 6" and 8" body diameters. All coaxial trap bodies are made of type 304 stainless steel and are offered with a choice of hose or flange style connections. Del-Seal™ CF metal seal flange connections have one fixed and one rotatable flange for alignment purposes. Kwik-Flange™ ISO KF and Large-Flange™ ISO LF flanges are clamp-style. Hose connections may also be welded, but permanent installation must be carefully evaluated. Contaminated traps may be cleaned with a solvent and allowed to dry before replacing into service. MDC recommends having a spare trap or filter element available for rapid replacement to minimize down time during the cleaning process. Filter elements are not included with trap assemblies; they must be ordered separately from the tables in Filter elements.
