Oil mist filters

The Nederman Filtac OMF range of oil mist filters are designed to eliminate the negative effect that oil mist can have on employee health, productivity, production equipment and overall business revenue.

Oil mist is comprised of liquid droplets generally up to 20 microns in size whereas high speed machining can generate mist drops that form a liquid smoke with droplets less than 1 micron. To effectively capture these extremely small droplets, Nederman has developed its FibreDrain technology.

Incorporated into the new line of Nederman Filtac OMF units, the FibreDrain filters capture even the smallest submicron droplets and drains them back to the process. The fluid drainage capacity is said to ensure maximum coolant retrieval and to reduce coolant consumption. The FibreDrain design is also said to extend filter life and reduce operating costs. 

With six models in the OMF Series, the modular range offers an airflow from 1000 to 6000m3/h with an inlet diameter that extends from 150 to 400mm diameter. Available as a free-standing vertical design that sits alongside the machine tool or as a horizontal system for mounting upon the machine, the OMF has the option of two or three filter stages depending upon the chosen model. These filters are easily accessible for cleaning or replacement, which reduces the maintenance requirement and machine downtime.

The first filter stage consists of a cassette with Filtac's FibreDrain technology whilst the secondary stage consists of a HEPA filter in Class H13 with an efficiency of 99.95%. The performance of these individual filters can be monitored by gauges that indicate any drop in pressure. The separated oil is collected in the bottom of the unit where it can be drained to a container, a pump box or re-circulated directly back to the machine tool.
