The Haas Coolant Mist Condenser is a closed-loop recirculation system that removes coolant mist from the machine’s enclosure, without venting it to the outside.

The unit works by drawing mist-filled air from the machine enclosure, and passing it over a sheet metal panel with a lipped edge. As the air passes over and around the panel, the coolant mist condenses into droplets. As more mist condenses, the droplets become heavy enough to drip off the panel’s lip and back into the enclosure.

After passing over the sheet metal panel, the air travels through a dual filter box to remove any remaining coolant. The mist-free air is then returned to the machine enclosure through heavy-duty ducting.

The system has proven very effective at quickly clearing the air inside the machine enclosure of coolant mist, so the operator can open the door immediately after machining is complete.
