Metalworking Fluid mist is a serious health concern for machine operators. Nova GREEN LINE Series from 3nine may be a step in the direction of reducing this health hazard. Nova 300 is suited for all applications involving processes using metalworking fluids or neat cutting oils. It works on all machine tools with a cabin volume up to 70CF and has a flow rate capacity of 176 CFM (300 m³/h) . They claim their unique patented technology, based on disc stack separation, will separate 100% of particle sizes down to 1μm by using centrifugal force. The machine is attractive and internally accessible. The data is impressive as well. At the end of the day, your chamber has to be sealed and the lower the volume the better the cleaning.
