ScandMist units manage the oil mist emissions from production facilities such as CNC machine shops and are particularly popular in high-volume manufacturing environments that require filtration systems for entire production lines. These high capacity systems are designed to operate as part of a local ventilation system and can handle air flows from 6,000 m³/h to over 100,000 m³/h. These units are modular in design so to increase the capacity of the filtration system several units can be linked together with a common inlet and outlet.

Filtration Stages

  • In the first ScandMist stage, multiple layers of pleated media collect the oil or coolant, allowing it to drain to the base of the unit. The filter media does not absorb the oil, but rather coalesces the ever-increasing droplets until they are heavy enough to drain. Contaminated air passes through the filter media where oil particles are attracted to the oleophobic fibres. The oil droplets continue to collide with the fibre and grow in mass. As the oil drop becomes bigger, it becomes heavy enough to fall against the airflow to the base of the ScandMist unit. Here, it can be collected or drained straight back to the machine tool sump.
  • The scrubbed air is then passed through a second coalescing filter, where the process is repeated. This second coalescing filter has a higher filtration efficiency than the initial stage and captures the smaller oil particles that were not caught in stage one. After this second filtration stage, the air is on average between 95 – 98 % free from oil mist.
  • The third filtration stage is designed to completely clean the remaining air to a standard far higher than the surrounding ambient air. Using a HEPA filter, this final stage ensures that fine, sub-micron particles — trace oil, smoke, bacteria, pollen and spores — are trapped and not allowed to return to the workshop. ScandMist employs an H13 (to EN 1822) HEPA filter that provides 99.95 % efficiency at 0.3 μm. This means that in a workshop environment, effectively all hazardous particles are trapped and only clinically clean air is returned to the workshop


  • 2 coalescing filters.
  • Third stage Hepa filter.
  • 11kW motor.
