Abstract: A Filtering System which is capable of handling large quantities of coolants and the System includes a reservoir for filtrates as, for example, from metal-working machines. The filtrate is returned to such machines by a pump which draws some of it from the reservoir, passes it through an eductor and then returns it to the reservoir. In operation, suction is applied to the outlet side of the filters to cause flow through them. In addition, valve means are provided so that the pump discharge can be used to clean the filters.
