Eriez HydroFlow manufactures an array of compact filter systems. The products in this line include Gravity Filter Systems, Magnetic Coolant Cleaners and Hydrocyclone Separators.

The Eriez HydroFlow Gravity Filter Systems product line refers to filters that use gravity to force dirty coolant through the filtration media. These systems are primarily used for industrial machine applications, but large flow cell type systems can be offered. Gravity Paper Systems employ disposable roll media for filtration and are ideal for grinding applications. Gravity Drum Systems employ a permanent stainless steel or nylon mesh filter media and are ideal for machining applications, particularly aluminum machining where floating chips are present. Standard units are designed with low coolant entry height, allowing for gravity return from the machine tool.

Eriez HydroFlow Coolant Cleaners keep machine tools running longer and more accurately with lower costs per unit produced. As stand-alone units or in conjunction with the Gravity Bed Filters, Magnetic Coolant Cleaners provide media free removal of ferrous contaminants down to 50µm.

Hydrocyclone Separators from Eriez HydroFlow are media free systems that use centrifugal force created by a feed pump to separate solids from liquids. Dirty coolant enters the cone through a vortex tube, which causes the coolant to swirl downward. The solids in the coolant are forced to the outside of the cone and exit through an underflow outlet at the bottom. Clean coolant flows back up through the vortex column and is discharged out the top of the cone.
