3 Key Factors for Designing Vacuum Pump Inlet Filtration ...

A standard 10 or 5 micron filter will trap a portion of the smaller particulates but over time there will be a buildup of small diameter contamination in the vacuum pump. Some vacuum pump technologies are able to handle this situation without incident but many other technologies will have severe problems ingesting a heavy load of small particulates. The result will be vacuum pumps that need to be taken off line to
