The patented magnetic filter element attracts ferrous wear particles down to 4 microns and below with up to 95+% efficiency. The magnetic filter element attracts both ferrous and non-ferrous particles. The radial magnetic field design offers incredible holding strength and a high dirt holding capacity. OEI magnetic filter elements are employed in various housings designed with calculated dwell times for optimal filtration. Magnetic filter elements come in five sizes from 1/2” to 2” outer diameter (OD).
CLEAN AND REUSE
OEI products are reusable for 18+ years, and require minimal consumables. Conventional filters
require frequent, costly changeouts, and disposal.
OEI Magnetic Filter Elements are effective predictive maintenance tools when used for condition
monitoring. When removed for inspection, magnetic filter elements will have varying quantities
of contamination. Abnormally high quantities of contamination indicate component failure. The
composition of contamination will identify which components are stressed, worn, or failing.
Visual analysis of the quantities of wear contamination collected on magnetic filter plugs can
determine component failure. Analysis of wear particle compositions and sizes will determine early
GOES WHERE NO CONVENTIONAL FILTER HAS GONE BEFORE
OEI magnetic filters can be installed on suction lines to protect pumps without risk of cavitation.
Unlike conventional filters, they accommodate space restrictions and unique applications such as
splash oil gearboxes, reservoirs, and small coolant lines.
CAPTURES NON-FERROUS CONTAMINATION
Non-ferrous particles are magnetically captured because of cross-contamination. Particles become
statically charged from flow velocity. This charge is a principal force of particle adhesion; iron
particles contaminate non-ferrous particles by adhering to their statically charged surface. Another
form of cross-contamination occurs when sub-micron iron particles embed in softer non-ferrous
particles after abrasive impact.
PREVENT OXIDIZATION AND VARNISH
OEI effectively removes iron and steel particles under 10 microns that are known to promote oil
oxidation because of their catalytic properties. Oxidation can deplete additives that protect against
wear, corrosion, sludge, varnish, and viscosity changes that affect the thickness of films between
bearing surfaces, friction, control of temperature, and energy consumption.
NO WORMHOLING OR CHANNELING
OEI filters eliminate the opportunity for wormholing and channeling that conventional paper,
fiberglass, and polymer media filter elements are subject to.
Wormholing: when wear contamination punctures the filter media.
Channeling: when fluid flows through punctured holes because it takes the path of least resistance.
