Coaxial Foreline Refillable Traps (metal sieve traps) use a fibrous stainless steel mesh for removal of hydrocarbons or large particulates. The coaxial design provides maximum filtering and flow. The two piece design allows for easy cleaning and removal/replacement of the filter element.

Will reduce or eliminate the undesirable effects of mechanical vacuum pump oil backstreaming. The Assimilation trap is one of the most effective, durable and easy to use foreline traps.

Construction is of 304 stainless steel with an easy open body by way of a machined flange set held together with a unique quick toggle stainless steel clamp.
