Coolant Filtration - MicroTech GravityFlo Filter

The MicroTech GravityFlo Filter (MGF) is an automatic gravity filter designed for cleaning all types of water based coolants. The MGF is a simple yet very effective paper roll media filter that provides continuous removal of grinding particles from metalworking coolant. GravityFlo filters assure a consistent supply of clean coolant which is filtered down to 20 - 30 microns at flow rates up to 100 GPM. They are an economical option to roll media vacuum filters or pressure filters.
