In a high vacuum setting, traps and filters may be installed on a vacuum foreline, but each has a different function:

Traps: A trap is a device that is designed to capture vapors and gases.

Filters: A filter is a device that is designed to capture or reduce particulates, dust, smoke, and aerosols. A common filter function, for example, is to captu... (read more)

Water cooled traps protect mechanical pumps and other downstream components from condensable process gasses and their by-products. They can extend or eliminate preventative maintenance intervals and pump overhauls. (read more)

These traps remove particles that might enter the mechanical pump and contaminate the oil. A polyester felt filter traps particles over 10 microns in size at 98% efficiency. Filters can be cleaned with a vacuum cleaner. Suitable for process temperatures from ambient to 149ºC. (read more)
