Posi-Trap®
Single Stage Vacuum Inlet Trap
- Positive Flow
- No "blow-by"
- Variety of elements
- Positive trapping
- Easy changing and cleaning
The flow of the effluent gas is directed through the inlet port to the filter elements. Unlike other traps, the filter elements of the POSI-TRAP® are sealed at both the inlet and the exhaust ends, eliminating blow-by and maintaining a positive flow through the elements. This means all contaminants must pass through the filter medium.
Choose from stainless steel gauze, copper gauze, molecular sieve, SodaSorb®, activated charcoal, and PolyPro (2, 5, and 20 microns). One (4" Posi-Trap) or four (8" Posi-Trap) filter elements are required per trap .
