OMF Coolant Mist Filters

Central Coolant Mist Systems

OMF coolant mist filters are stand-alone central filtration systems designed for extraction of mist from multiple machine tools.

Ranging in size from the small OMF500 to the OMF4000 which draws 4000m³/h, units can be specified for most mist filtration installations.

The OMF range has recently been updated to a new modular system, meaning filter stages can be specified for each application with ease. An optional metal mesh filter section allows for an additional protective filter to be fitted if required. Additional second stage filter modules can be retrofitted if applications change.

We are able to specify, supply, and install OMF filter units, including wiring to your machine tools for ease of operation.
