Coaxial foreline traps offer easy maintenance and room temperature operation, they require no bakeout or cooling and are virtually maintenance-free. They are ideally suited for trapping roughing pump hydrocarbons and preventing them from backstreaming into a vacuum system. Single piece coaxial foreline traps contain absorbent filter cartridges filled with a bronze wool element. This filter element is permanently sealed inside the trap's body and can't be removed or replaced. These traps are serviced by replacing them with a spare unit while cleaning the contaminated trap. Single piece traps are available in 4" and 6" body diameters.

Trap bodies are manufactured from type 304 stainless steel. Traps are offered with a choice of hose or flange connections in seven sizes. Del-Seal™ CF metal seal flange connections have one fixed and one rotatable flange for alignment purposes. Kwik-Flange™  and Large-Flange™ ISO flanges are clamp-style. Hose connections may also be welded, but permanent installation is not recommended. Used traps may be cleaned with a solvent and allowed to dry before replacing into service. MDC recommends having a spare trap available for rapid replacement to minimize down time. The used unit may be cleaned and stored for re-use as convenient.
