Metal Sieve

Metal Sieve Traps

Ebara metal sieve traps are provided with a fibrous stainless steel sieve for removal of hydrocarbons which backstream toward the chamber when the mechanical pump oil is at its vapor pressure.

Standard designs include a sealed, single piece, coaxial body and a two-piece, clamped body with coaxial or right angle port configurations The sealed trap design requires removal from the system before cleaning. The two-piece clamped body design makes disassembly, cleaning and sieve replacement a simple task. For proper sealing of two-piece body traps, apply a light coating of Krytox lube when cleaning or replacing the O-ring.

Standard body finish is beadblast. Electropolish finish, larger body sizes, CF, EVAC and ASA flanges are also available. Call for pricing.

Copper sieve is available as an option at no additional cost. Add "-CS" to model number. The body Range option is also available for 4, 6 and 8 inch trap bodies. Add "-BF" to model number.
