Grafting Process Shows Improvements in Contaminant Reduction in Engine Oil

September 5, 2001

puraDYN Filter Technologies Inc. announced Sept. 5 that the new filter elements featuring the Company’s patented grafting process have exceeded expectations in extended field test updates. The announcement was made by Kevin G. Kroger, president/COO of puraDYN.The tests include two class-8 trucks owned by Vulcan Chemicals in Wichita, Kan., a business unit of Vulcan Materials Company, which were equipped with new puraDYN by-pass filters earlier this year. The trucks are operated under normal conditions and the new data shows that one truck has traveled nearly 125,000 miles (5 times longer than the current filter change of 20,000 miles) without the need for a traditional oil change or puraDYN® filter change. The second truck has traveled more than 67,000 miles without an oil change or puraDYN filter change.The only maintenance performed on the trucks’ oil filtration systems has been at 20,000 mile intervals at which time an oil analysis was performed, according to the company, which says each analysis has shown that the oil supply in both trucks is clean, conditioned and suitable for continued use. The maintenance schedule also calls for the replacement of standard full-flow filter at 80,000 miles.“The field test data support the laboratory test results we had received during development of our new patented grafting process to improve our filter elements’ ability to remove soot and other solid contaminants,” Kroger said. “We are responding to the industries’ concerns of increased soot contamination in the new engine lubricating systems and are dedicated to providing our customers a filter that is a major source of savings in maintenance costs, conserving the consumption of new oil and reducing the amount of waste oil generated. Test results in both laboratory tests and in the field continue to show our commitment to excellence in by-pass oil filtration and setting new standards for the industry.”For its new filters, puraDYN says it has implemented patented technology that provides several improvements over previous puraDYN filters including:- CGP™: This new technology for chemical grafting improves the attraction and retention of soot and other solid contaminants to the packed cotton filter material, according to puraDYN.- Ease of maintenance: The filter element of the new filter can be replaced in a matter of seconds, according to puraDYN. Simply twist off the lid – pull out the old filter – and drop in the new one.The company has installed puraDYN filters on its entire fleet of class 8 trucks. “The performance of these two new filters has exceeded any of our expectations,” said Douglas Webb, logistics supervisor for Vulcan. “We want to express our gratitude to puraDYN for substantially lowering our costs associated with oil changes.”About puraDYNpuraDYN manufactures and markets the puraDYN By-Pass Oil Filtration System, a unit that continuously filters lubricating and hydraulic oil by reducing solid contaminants down to 0.25 micron, as well as removing liquid contaminants, therefore maintaining the oil’s viscosity and greatly reducing or even eliminating the necessity for oil changes.As a result of this continuous process, the useful engine and hydraulic system life can be extended, according to puraDYN.According to puraDYN, the system is effective for internal combustion engines, hydraulic applications and automatic transmissions in the automotive, transportation, construction, marine, agriculture, mining, military and power generating industries.The puraDYN By-Pass Oil Filtration System has been certified as a "Pollution Preventing Technology" by the California Environmental Protection Agency.For more information, visit www.puradyn.com.
