One Eye Industries


One Eye Industries introduced an innovation to magnetic filtration 17 years ago with application on all rotating equipment found in oil and gas, mining, construction, wind, food, manufacturing and marine industries.This is a cleanable, reusable technology that offers an environmental alternative to disposable depth media filtration.


OEI filtration technology is unique in that it filters contamination to sub-micron levels with minimal flow restriction, maximizing efficiency.

OEI filters are engineered for individualized applications to account for flow rate, pressure, temperature, viscosity, space, ports, as well as multi-direction flow.

OEI technology is currently installed on water, gas, lube oil, fuel, condensate, LNG, LPG, glycol, coolant, chemical and oil applications.

Patented Design

OEI designs magnetic filter rods using the highest-grade neodymium and samarium cobalt rare earth magnets. These magnets are then installed in a stainless steel encased magnetic rod with radial fields for optimized magnetic field strength.

Ceramic and low-grade rare earth magnets are unable to effectively filter below 5 micron contamination due to loss of field strength when exposed to temperature variance and vibration.

This radial field design allows for a large surface area for capture, therefore a high contamination holding strength. Because of the design and the quality magnets, OEI Magnetic Filter Rods are powerful enough to filter both ferrous and non-ferrous contamination to sub-micron level. Contamination below 5 microns in size is the most damaging because machine components (such as bearings, servo valves, meters etc.) are subject to failure due to low tolerance of wear particulate.

OEI Magnetic Filtration captures non-ferrous contamination through two methods: static adhesion and entrapment. With static adhesion, the flow of liquid induces an electro-magnetic charge to the particulate which is then attracted to the radial magnetic fields. Entrapment occurs from cross contamination of sub-micron iron particulate and non-ferrous particulate. This occurrence is found in all fluids and oils used in rotating equipment.
