Our flex traps are provided with fibrous stainless steel sieve for removal of hydrocarbons which backstream toward the chamber when the mechanical pump oil is at its vapor pressure.
Copper sieve is also available as an option by adding the suffix “-CS” to the model number at no additional cost. The flex trap’s two-piece clamped body design makes disassembly, cleaning and replacement of the sieve a simple task.
Coaxial and right angle port configurations are available with 2, 4, 6, 8 and 12 inch OD bodies with port ODs from 1/2 to 8 inches with or without NW, ISO, CF or ASA flanges.
These traps are being phased out and are being replaced by the traps from Solberg. Please see https://www.duniway.com/catalog/mech-pumps/solberg-intakeexhaust-traps .
