I had a Koolmist system which seems as if it was like the Bridgeport system that you mention but I was never really happy with it. I was forever having to adjust it. A year or so back I made a new block with rearranged passages and I replaced the coolant tank with a filter housing similar to the one in the video, which allowed for the coolant to be pressure balanced to the air flow. The system works much better now. It is no more complicated than the original, just different. The block was replaced with another and the coolant tank was replaced with the filter housing. None of the complication of the video.
When I had my Bridgeport, I usually ran Chevron soluble oil B at a 10 to 15 to 1 ratio coolant, and I always seemed to neglect cleaning out my tank, frequently the mix might stay in the tank for weeks maybe longer if I wasn't doing any milling, sometimes it would be left in the tank so long I would even have to add a tablespoon of bleach to get rid of the Monday morning stink. I don't remember having to fiddle with adjusting it all that much, as I would normally just open the valve and nozzle pretty wide
