One Eye Industries

One Eye Industries (OEI) is a company located in Calgary, AB, Canada that designs and produces magnetic filters employed internationally by leaders in oil and gas, mining, commercial and residential building, manufacturing, transportation, food, pharmaceutical, defense, petrochemical, and marine industries. Company’s mission is to be the trusted partner of industrial machinery operators around the world.

Customers choose OEI products beacause it is the simplest way to achieve rapid payback with the lowest risk by extending the life of rotating equipment. As a result, safety is improved while substantially reducing costs and the environmental impact of operations.

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).

Industries OEI serves


OEI provides unique solutions with proven success protecting high-pressure pumps, compressors, and injectors, as well as standard systems such as hydraulics, reservoirs, engines, and gearboxes.


OEI offers innovative and performance-driven magnetic filters that reduce plant operating costs. OEI filters have application on all rotating equipment in midstream and downstream plants.


OEI has an extensive range of products tailored to meet the demanding applications of power generation facilities. Filters protect equipment, reduce downtime, and improve profitability.


OEI magnetic filtration meets the demand for pulp and paper processing with minimal flow restriction and optimized application designs. These filters are perfect for pulp slurries and produced water.


Effective filtration of industrial manufacturing fluids is critical to facility operations and product quality. Filtration is important for CNC machining, parts washing, hydraulics, water systems, and engines.

food production


In food production, contamination can manifest in the water, air, blending, processing, storage, or transport of product. OEI filtration improves final product quality of fresh and processed foods.



Effective filtration within aircraft and military equipment is vital to ensure all systems are protected from wear contamination that damages system components and leads to equipment failure.


Mobile equipment costs are ever increasing from operation, labour requirements, and capital investments. OEI filters reduce costs by minimizing fluid, filter, and component replacement.


OEI filters prevent scored injectors, damaged engine components, poor lubrication quality, and deteriorated hydraulic components to ensure responsible, cost-effective equipment operation.



Boilers, chillers, water loops, and heat exchangers all require quality filtration of hard wear particles (iron, silica, sodium) to protect tight-tolerance components from wear and failure.


OEI cleanable filters require maintenance intervals of 6 months to 1 year. We strive to be the most trusted partner for maintenance technicians operating in the most demanding locations.



The global impacts of fuel emissions and water quality are provoking governments to source clean technologies for improved municipal operations. OEI meets the requirements for these types of initiatives.
