Screw machines are essentially automated lathes that are used to quickly mass-produce parts; in doing so, many can produce oil mist as a byproduct of the cutting process, which uses various forms of coolant.  The idea is to create a slight negative pressure environment within the machine enclosure, to reduce or eliminate the overspray and smoke that can plume out of the cabinet when opened.  Certain precautions should be taken, though, because if the mist eliminator’s airflow is set too high, it can make it VERY difficult to open the access door.

Most screw machines are very easily accommodated by a low cfm mist collector attached directly to the enclosure.  Some circumstances will deem that the mist eliminator should be ducted into a port on the machine, or a more powerful mist collector can be used to service multiple machines.

There are certain types of applications that require different filtration methods. For example, if you have extensive production hours or long cycle times, ESP may be more beneficial to use rather than replaceable media, which can increase machine downtime if the filters are constantly getting plugged and soaked.

This should be a pretty good start for this category; feel free to post comments, experiences, etc… After all, this is a blog!
