Feature Case Study

ROI: Eliminated Valve Failures

Annual Cost Savings of $25,200


Calgary, Ab Canada / 2013

Rand High Pressure Air Compressor

Lube Oil

Moisture in the air system was causing corrosion
of the carbon-steel piping was producing high levels of contamination in the system.
The contamination was prematurely damaging the solenoid valve rubber seals. The damage forced the valves to remain open resulting in the need to replace them monthly. The valve failures were inhibiting production. In an effort to reduce unscheduled downtime and the monthly expense of replacing the valves, the maintenance team removed them all together.

Install an OEI magnetic filter Y-Strainer before the solenoid valves to remove the sub-micron wear particles that were damaging the seals.


The photo shows contamination removed from the system after two weeks. The air flow is now clean, and the valves were re-installed. A similar amount of contamination is removed every three weeks during cleaning. If left in the system, these contaminants would continue to cause premature valve failure.

The annual savings realized from eliminating the replacement of 3 valves each month ($700/valve) can be equated to $25,000. This does not include the cost savings realized from preventing unscheduled downtime.

Excessive amounts of ferrous and nonferrous contamination in the circulating oil system of the gearbox were causing several problems including premature wear of the gearbox and its components as well as shortened life cycles of the oil/lubrication.

Hydraulics and Pneumatics

Finishing Line Pneumatic Control Valve Protection

The challenge was to reduce downtime due to pneumatic control valves failing every four to six weeks. This is a common occurrence in pneumatic systems due to pressurized air producing wear contamination under 10 microns. Rust and slag are also produced in pressurized air environments which results in the plugging off of seals and pneumatic system components.

Powepure Hydraulic Test Bench

Traditional filtration is unable to remove contamination below ten microns and the company wanted to ensure the life of their pump. Upon start-up there is much wear debris that is passed through the system due to machining and fabrication.

Kinecor Pump Hydraulic Test Bench

Kinecor offers their customers a hydraulic testing facility to ensure that serviced equipment is functioning properly. It is powered by an 8V92, 470 horse power, Detroit Engine and has a 300-gallon hydraulic reservoir. A 2-micron filter is installed at each of the two hydraulic returns to protect the $250,000 test system from older equipment, which typically has high levels of ferrous contamination.

Medisystems Injection Molding Hydraulics

High level of ferrous contamination as a result of premature failing of pump components causing OEM filters to clog once a week resulting in downtime for repairs. To complete the production run they would have to leave the failing pump in service. The OEM filters would not allow them to maintain production because they were unable to remove the large volume of fine wear contamination.

PT Ecco Tannery Hydrulic Press Shoe Factory

Ferrous metal contamination with particles down to sub micron in size the traditional filtration is unable to remove resulting in seal failure and scoring of the hydraulic piston shaft.

Specialty Laminate Wemhoner Hydraulic Press

Tutty approached One Eye Industries (0EI) with the hope that he could at least keep his 4,500-pound Wemhoner presses running without interruption. A OEI Magnetic Base filter rod was immediately installed at the inlet and the outlet of the Wemhoner’s 250-gallon hydraulic reservoir.

Ford Truck Factory Hydraulic Press

Install an OEI 24” Magnetic Filter Rod (3RNPT24ES) with protective screen. The screen is recommended because the length and location of the rod is near the exterior of the reservoir. If the rod were to attach to the reservoir removal would be problematic.

Jager Manufacturing Plant Hydraulics

375% drop in Ferrous Hydraulic Contaminants under 10 microns
One Eye Industries, specializing in longterm industrial filtration solutions, partnered to support the efforts of Jager’s plant maintenance program. Implementing a test study, JBS installed the FM4000 Scrubber on the feed side of plant hydraulic equipment before, and then after, their standard filtration systems to evaluate present filtration capabilities and effectiveness.

After one week of operating time with an OEI Magnetic Filter an abundant amount of ferrous metal was extracted. After these results they also installed OEI Magnetic y-strainer on the air/water system, to remove slag from the pipes as they are formed.

Parts Washers & Milling Machines

Gildermiester Milling Machine Cooling Fluid Filtration

The challenge was to prevent metal filings from filling the cooling system to avoid overheating and shutdown. The traditional filtration in the Gildermeister machine’s cooling system was not providing effective filtration and, therefore, the machine’s radiator was filling with metal filings. As a result, the machine was running at temperatures from 32-34 degrees Celsius (shut down would occur at 35 degrees). This was causing frequent unscheduled downtime for cooling system maintenance.

Ariston Parts Washer Quality Control

The challenge was to reduce contamination in the parts washing fluid to meet quality control cleanliness levels for painting.

The challenge was to clean cooling/cutting oil contaminated with wear particles, to prevent wear on system components. 

Improving Cleaning Capability of Linamar’s Hotsy Parts Washer

The challenge was to reduce fine ferrous contamination, under 10 microns in size, which was missed by 40 micron nominal filter bag. Linamar’s specifications for parts cleanliness were not met, and the secondary washer was considered.

Husky’s Injection Molding System Protection

The traditional drum filtration system was ineffective in filtering the cooling/cutting fluid thereby reducing the fluid’s operational life. The contaminated fluid caused premature wear  on the cutting dies, decreasing the system pump life. The challenge was to remove ferrous contaminant from the fluids to submicron particle levels. 

Improving Linex Parts Washer Cleanliness

The challenge was to remove ferrous contamination from the washing fluid because products were consistently rejected due to lack of cleanliness, even though the parts are passed through three washing systems. 

Danieli Corporation Cutting Coolants

The traditional filtration system (yellow arrow) was not cleaning the fluid efficiently thereby reducing the fluid life, prematurely wearing the tools and reducing production.
