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.
