Foreline trap

HHV’s Foreline Trap has a cylinder filled with activated alumina which absorbs oil vapor typical of those generated by rotary vacuum pumps. When placed in the backing line of a diffusion pump or between a roughing pump and the vacuum system it can reduce back streaming of hydrocarbon contamination to negligible levels.

The Foreline Trap is made of SS body with quick seal type (KF-TYPE) inlet, outlet connections, to suit all our ED series pumps. Foreline Trap is fitted with built in heater for regeneration of the molecular sieve. This trap is available in two models FT-25H and FT-50H for 1" and 2" connections respectively.
