puraDYN Unveils New By-Pass Filter Technology At TMC Show

    NASHVILLE, Tenn.--March 14, 2001--puraDYN(TM) Filter Technologies Inc. unveiled the next generation of its by-pass oil filtration systems at The Maintenance Council of American Trucking Associations Inc. (TMC) show in Nashville, TN on March 11, 2001.
    The product was introduced by Kevin G. Kroger, President and COO of puraDYN.
    Similar to the company's previous units, the new puraDYN by-pass oil filters allow engines to operate for hundreds of thousands of miles without the need for a traditional oil change. This substantial reduction in oil changes permits puraDYN customers to save significant maintenance costs including up to a 90% reduction in the need for new oil and the amount of oil for disposal.
    "Our new generation of filters utilize cutting-edge technology to maximize the ability of our by-pass filters to keep engine oil constantly clean and conditioned," said Kroger. "We have introduced the new generation of filters to work with the latest engine and lubricant technology and to assist fleet and individual truck owners in saving money and preserving the environment."
    As with puraDYN's previous system, the new generation of filters clean, reduce and maintain oil contaminants down to 0.25 micron (standard full-flow oil filters maintain contaminants in the 15 - 40 micron range). By continually removing contaminates and replacing vital additives through its patented time-release additive package, puraDYN's filters substantially extend intervals between oil changes.
    For its new filters, puraDYN has implemented patented technology that provides several improvements over previous puraDYN filters including:

-	CGP (Chemical Grafting Process): This new technology improves the attraction and retention of soot and other solid contaminants to the packed cotton filter material.
-	Increased oil distribution within the filter: New product engineering distributes oil more evenly throughout the main filter element. This reduces the effect of "channeling."
-	Ease of maintenance: The filter element of the new filter can be replaced in a matter of seconds.

    puraDYN developed the new filter technology over the past three years. Field testing was conducted over the past 30 months. The consolidated results from across the country show that test vehicles averaged more than 160,000 miles without the need for a traditional oil change. In addition, 1800 hours of in-house and independent testing has been conducted on the new filter. No oil related problems were experienced during laboratory or field testing.
    The filter elements for the new generation of puraDYN filters have been designed so they can also be used with all previous puraDYN units.
