A cheap filter replacement for Ulvac G-100DB oil mist filters

Ulvac rotary vane pumps shipped with many different JEOL SEM's (and probably others too) have an oil mist filter cartridge, and if you don't want to buy an OEM cartridge, you can make your own. Thanks to Spirit for the suggestion, so I thought I'd make a video showing how I did it. Original link: https://fixupx.com/Spirit532_/status/... Music by ZenMan on pixabay, free use with credit
