Puradyn Filter Technologies Incorporated designs, manufactures, markets and distributes the Puradyn bypass oil filtration system (the Puradyn system) for use with various internal combustion engines and hydraulic equipment that use lubricating oil. Working in conjunction with the equipment's full-flow oil filter, the Puradyn system cleans oil by providing a second circuit of oil filtration and treatment to continually remove solid, liquid and gaseous contaminants from the oil through a filtration and evaporation or absorption process. The Puradyn system consists of a base filtration unit or housing that is connected via hoses to the engine or hydraulic system, along with filter elements that reside inside the filtration unit and are replaced periodically. The Company also manufactures disposable replacement filter elements (Element) for the Puradyn system. The Puradyn system is offered in approximately three families of models, Millennium Technology System (MTS), TF and PFT.
