COAST FILTER TEST RESULTS:
In this test conducted with joint cooperation of both Gulf Coast Filters and Scott Paper Co., the following test objective for the GCF Filters was established:
TEST OBJECTIVE: To safely extend lube oil drains to at least 1,000 runtime hours and eliminate routine hydraulic fluid drains. Also to reduce the amount of solid contamination within engines and hydraulic systems, thereby reducing the amount of component wear.
OUTLINE OF TEST:
In July of 1992 the following pieces of equipment were outfitted with GCF By-pass Lube & Hydraulic Oil Filters:
The lube oil and hydraulic fluid within the test equipment was monitored by complete spectrometric oil analysis, automatic particle counts, and the GCF Model LS-HS portable oil quality analyzer, which offers dielectric oil quality testing. The GCF Lube Oil Filters were installed approximately midway through the equipment's normal 100 to 150 hour oil drain interval. From this point the oil was not changed within the engines or hydraulic systems, but rather the GCF Filters were changed each 100 hours. Listed below is a brief summary of the accomplishments achieved by the use of the GCF Filters during the 1,000 hour test.
1. 1,000 HOUR OIL DRAIN INTERVALS REACHED: Analysis taken during the test period showed that oil drains could be safely extended to 1,000 hours. The lube oil within the test equipment at the end of the test was still suitable for further use and was far above the engine manufacturer's requirements.
2. MASSIVE REDUCTIONS OF SOLID CONTAMINATION: Particle counts taken of the hydraulic fluid from the Loader and Hydro-Ax both showed massive reductions of solid contamination. There was an average of 98% reduction of solid contamination within the hydraulic system of the Loader Crane. A sample taken from the Hydro-Ax equipped with the GCF Filter and a sample taken from another Hydro-Ax, not using the GCF Filter, also showed the efficiency of the GCF Hydraulic Filters. The Hydro-Ax using the GCF Hydraulic Filter had an average of 80% less solid contamination than the Hydro-Ax not using the GCF Filter.
3. WEAR RATES WITHIN ENGINES WERE MAINTAINED FAR BELOW THE ENGINE MANUFACTURER'S ALLOWABLE LIMITS: Wear rates in critical wear metals, such as Chrome, Iron, Copper, etc., were maintained far below the engine manufacturer's allowable limits. There were many cases in which wear rates were actually reduced during the 1,000 hour test.
4. REDUCTION OF WEAR WITHIN HYDRAULIC SYSTEM: Large reductions of wear within the hydraulic systems were achieved by the use of the GCF Hydraulic Filters. Both the spectrometric analysis and the Automatic particle counts showed massive reductions of wear within hydraulic components. The photo micrographs, taken with a magnification of 100X, showed visual signs of the larger 50 to 5 micron size wear particles being greatly reduced. Also, the spectrometric analysis also showed a reduction in the much smaller wear particles below 1 micron in size.
5. 78% SAVINGS ON LUBE OIL, FACTORY FILTERS, AND LABOR COST:
6. REDUCTION IN DOWNTIME: A reduction in downtime can be seen from no longer having to perform routine hydraulic Fluid drains, less downtime from routine oil drains, and less downtime for repairs on hydraulic systems, due to failures from contaminated Fluid.
7. LONGER EQUIPMENT LIFE EXPECTANCY: Due to running the engines and hydraulic systems on cleaner oils and fluids, the equipment would be compelled to have a longer life expectancy. This is further enforced by the facts from the spectrometric and particle count analysis. Less wear was seen within the test equipment, therefore the equipment will last longer.
