Often it's overlooked that the mist droplets also contain a very fine solid particle of the abrasive of the metal being machined. After the worker has the first "opportunity" to inhale it, the droplet settles on a surface like lighting, floors, machines, or work benches, where the mist evaporates, leaving its residue and the tiny solid particles to accumulate. Often called "smut", it's more than a housekeeping nuisance, causing respiratory and skin problems. Mistkop Mist Eliminators from AGET Manufacturing, captures the mist at the source before it's dispersed, traps the mist and drains the cleaned, often reusable fluid.  The system retains the solids in the filter for disposal.
