Posi Traps®

POSI-TRAP®

Posi-Trap vacuum inlet trap filter elements are sealed at both the inlet and exhaust to provide positive trapping of the effluent gas stream and eliminate “blow-by.” Forcing all particulates to pass through the filter medium, the Posi-Trap comes in a 4” (25 mm ports) model which uses one user selectable filter element and an 8” (40 mm ports) model that holds four filter elements. Made from stainless steel in straight-thru and right-angle styles, they are equipped with a quick-release clamp for easily changing the filter elements.

Key Features

  • Ensures positive flow with no “blow-by.”
  • All stainless steel construction.
  • Straight-thru and right angle styles offered.
  • Wide variety of filter elements to choose from:
  1. Sodasorb® filter elements are used for trapping acids.
  2. Copper Gauze filter elements have a large surface area to trap condensable particles and oil vapors.
  3. Stainless Steel gauze filter elements are the same as copper but with added corrosion protection.
  4. PolyPro 2 filter elements trap high volumes of solids and particulates as small as 2 microns.
  5. PolyPro 5 filter elements trap high volumes of solids and particulates as small as 5 microns.
  6. Activated Charcoal filter elements remove organic vapors.
