Visi-Trap Vacuum Trap
Vacuum inlet trap with a clear sump
The Visi-Trap is a vacuum inlet trap with a clear sump, so you can see when the insert needs changing. It works in both directions: it stops corrosive chemicals, particles and oil vapour reaching the pump, and it cuts oil backstreaming from the pump into the system.
Two sizes
| 300005 | 300010 | |
|---|---|---|
| Sump | 4.5″ (114 mm) | 9.5″ (241 mm) |
| Pump size | 1 to 4 CFM (25 to 100 l/min) | 5 to 15 CFM (150 to 500 l/min) |
| Height | 200 mm | 325 mm |
Both are 140 mm in diameter and need about 40 mm below the sump to remove it. The housing is polypropylene and the sump styrene acrylonitrile, with a polypropylene sump available. Ports are 3/4″ female pipe thread, with hose, NW25 or NW40 terminations fitted at the factory if ordered with the trap.
Inserts
The Visi-Trap comes empty or with an insert fitted: copper or stainless steel gauze, molecular sieve, soda lime, activated charcoal, activated alumina, or polypropylene at 2, 5 or 20 micron. The insert changes without taking the trap out of the line. A dial gauge, a vent valve, or both preassembled, and replacement sumps are available. Part numbers for every insert are on the filter elements page.
Where it’s used
Smaller laboratory and production pumps on freeze dryers and gel dryers, rotary evaporators, leak detectors, SEMs and mass spectrometers, and glove boxes. Mass-Vac also fits a Visi-Trap to each of its vacuum degassing chambers.
