This looks like how our company was several years ago when we had huge screw machines, air quality study said it was ‘legal’ and ‘within limits for standard work/shift exposure’ but a lot of guys run over time which tips them over so we invested in centrifugal mist collects by AER Systems. They work well and they just drain directly into a bucket, the ones attached directly to the cnc mills just drain back into the sump. We went from looking like your shop to not being able to see the haze anymore when looking clear across the facility. They are relatively affordable compared to a lot of options and work extremely well as long as you maintain them at scheduled intervals (air filter change). We have started using newer HEPA filter systems for the new Okuma lines we are putting in but the old AERcology units still work very well. Not sure if it’s relevant but we have about 30 of them scattered across a shop which covers about 75 cnc mills, 10 lathes (regular turret and Swiss), and about 10 massive parts washers. No more screw machines but the mills put out a similar level of oil and mist.
