MAGNETIC PREFILTER

［Application］
This prefilter removes fine iron powder from machining liquid discharged from a
wire electric discharge machine (WEDM). This can also be used for honing
machines and hydraulic circuits (under no pressure).
Install this prefilter at a point between a wire electric discharge machine and a
pump unit.

［Features］
●By roughly removing fi ne iron powder from machining fl uid with the
powerful magnet as a pretreatment, the service life of the paper
fi lter, for example, becomes two times longer.
●The prefilter collects impurities as well as fine iron powder.
Consequently, the paper filter to use may be of coarser type than
that of the straight infl ow.
●The duplex construction facilitates removal of fine iron powder.
