I want to purchase a coolant mist filter system onto my Haas DM-2 and just looking for some recommondations for what has worked for you.

I would prefer a system that doesn't need to exhaust out of the building ( so if possible I would like the style that drains back into the machine )

from the little research I've done it sounds like Royal brand is a nice unit, but just wondering if there might be a little more economical brand that may do the job.

Thanks,

Kent
