Award Permits Purchases of New Systems and Replacement Filters for Miami-Dade Equipment

�

puraDYN Filter Technologies Incorporated (AMEX:PFT) announced today that Hydraulic Sales & Service, a Miami-based distributor of puraDYN(R) products, has been awarded a blanket open purchase order allowing up to $650,000 for the purchase, installation and service of puraDYN(R) systems by Miami-Dade County. The open order is valid for a period of one year.

Fred Orig, Sales Manager of Hydraulic Sales & Service, said, "Miami-Dade County has been using the puraDYN(R) systems for a number of years and this purchase order means we will be able to keep Miami-Dade County well-supplied and serviced over the coming year."

Orig continued, "As a distributor for puraDYN since 2003, we have had considerable success in marketing, installing and servicing the puraDYN(R) line of products, especially now with the cost of oil hitting record highs on an almost daily basis. Payback on the puraDYN(R) systems usually runs about one year or less on the over-the-road equipment used by Miami-Dade."

Richard C. Ford, CEO of puraDYN, said, "This blanket purchase order demonstrates the ongoing demand for our filtration systems in Miami-Dade County. We know Hydraulic Sales & Service will be able to meet and service the needs of the County over the next year as it sells and installs the bypass oil filtration systems for various pieces of their equipment.

"The total number of puraDYN(R) systems currently installed on Miami-Dade County equipment now stands at over 2,000. This blanket open order will cover the purchase of approximately 1,000 systems in addition to replacement filters for their existing puraDYN(R) systems."

The puraDYN(R) bypass oil filtration systems work with the full flow filter to reduce solid contaminants in engine oil to below one micron with the use of its patent-pending CGP(R) filter element; to evaporate harmful gaseous contaminants; and to replenish the base additives so as to maintain the proper total base number (TBN) and viscosity of the oil. By maintaining continuously clean oil, oil drain intervals are significantly and safely extended thus reducing new oil purchases and waste oil disposal costs.
