Why should I buy an OMF rather than a cyclonic filter?
Cyclonic filtration is effective down to 10 microns. Below this level, efficiency drastically reduces. Coolant mist can be sub-micronic – the final stage HEPA fllter in an OMF allows for very high grade filtration.
In addition, cyclonic filters may require daily maintenance – compared to monthly maintenance for an OMF. This is a significant time commitment.
