Air Force, MEEP Management Office, Eglin AFB, FL
This is a one year study of PPI reusable oil filters: four on M-1097 (HMMWV’s), two on a 60KW stationary generator, and two on a 10KW stationary generator. The study concluded that, “the Spin-On Washable Oil Filters worked as advertised. The advantages of using the Washable Oil Filters are numerous. A large oil filter inventory, primarily at overseas locations and in mobility parts kits, can be eliminated, if a washable oil filter as a one-time purchase is used. Also, using washable oil filters eliminates the potential of a violation of base, state, and/or federal regulations when disposing of used oil filters. Based on overall test results, the Pure Power Filters were recommended for Air Force use.”
SAE J1858 Multi-pass Test, Southwest Research Institute
This test employed various sized contaminants which were injected upstream of the oil filter and allowed to flow through the filter for 40-60 minutes without pause. The Pure Power filter far exceeded the standard filtration of OEM filters, indicating 90% better filtration.
SAE HS806 Resistance to Flow Test, Southwest Research Institute
This test measures the amount of oil which can be circulated through an oil filter without the filter becoming “stalled” or incapable of allowing oil to flow through the filter because of excess differential pressure. The flow rate of the Pure Power filter was 20 gallons per minute at 65 psi, while the OEM filter in comparison only flowed 5.8 gallons per minute. The results show the flow to be 50% less resistant in the Pure Power Filter compared to the OEM Filter.
SAE ARP1400 Rev.B Burst Rate Test, Southwest Research Institute
This test was performed at the request of the FAA. The results showed that the filter withstood maximum pressure (1000 psi) with no failures and in good condition. OEM aircraft filters are not normally tested at more than 500 psi.
NASCAR Technical Institute Test, North Carolina, 2011
A Jack Roush NASCAR engine was used in this test. It showed 775.2 horsepower at 8,000 rpm with a Wix Filter and 778.2 horsepower at 8,000 rpm with the Pure Power Filter. An increase of 3 hp in this type of engine is significant.
Cummins Test, Pennsylvania
This test compared Pure Power Filters to OEM Filters on the ISB engine. The results showed that the Pure Power Filters surpassed the OEM Filters in flow, filtration and strength.
Mack Truck Test, Texas
This is a 17 month test comparing Pure Power Oil Filters with Spinner (a reusable filter and a centrifuge filter) Oil Filters. This test showed Pure Power Filters to be 50% more efficient than the other two filters combined in removing 10 um particles and smaller (these particles cause engine damage). Pure Power Filters also met or surpassed the Mack specifications Field Test.
STC from the F.A.A.,
Based on tests done at Southwest Research Institute, the F.A.A. issued a Supplemental Type Certificate which allows Pure Power Filters to be used for up to 100 flight hours before an oil change is necessary (in piston driven aircraft). Pure Power is the only cleanable oil filter to pass stringent F.A.A. testing and receive an STC for Lycoming, Continental and Rotax aircraft engines.
5 Gas Analyzer Test, State of Wisconsin, 2010
This test was conducted on a 980 CAT Loader. This test compared a new OEM paper filter (with new oil) and a Pure Power Filter (with new oil). Pure Power Filters showed a reduction in Nox, CO, HC. There was also a significant increase in oil pressure with the Pure Power Filter.
5 Gas Analyzer Test, B & K Trucking, Wisconsin, 2011
This test showed a significant reduction in Nox, CO, HC and CO2 with a Pure Power Filter over an OEM Paper Filter. The Nox went from 191 (paper filter) to 123 (Pure Power- a 35.6% improvement), the CO went from 0.04 to 0.02 (a 50% improvement), the HC went from 11 to 4 (a 63% improvement), and the CO2 went from 2 to 1.3 (a 35% improvement).
SAE J1667 Diesel Smoke Opacity Test, S & S Testing (BT 2000 Smokemeter), California, 2012
This is a snap-acceleration smoke test for heavy-duty diesel powered vehicles. The opacity meter showed 5, the Cal. Air Resources Board allows 10. The smoke density read out value varied between 4.5%-5.4%, for an average score of 5% in multiple tests on a Chevy Duramax 3500 truck.
