KleenAir Systems, Inc. (OTCBB: KAIR) believes that its NOx reduction technology will benefit significantly from the newly announced stringent EPA proposed regulations on NOx and particulate reduction for diesel-powered trucks and buses, in addition to earlier proposals for minivans, SUV's and pick-up trucks.

EPA Administrator Carol M. Browner on May 17 proposed measures to "reduce smog-causing nitrogen oxides from these vehicles (heavy-duty trucks and buses) by 95%. Soot and smog pollution is scientifically associated with 15,000 deaths annually, and a million cases of respiratory problems each year. They are also responsible for some 400,000 cases of asthma attacks every year, including thousands of aggravated cases of asthma, especially in children."

KleenAir has a unique computer controlled ammonia system, the NOxMaster(TM), which, when injected into the exhaust stream, interacts with NOx produced during combustion. The result converts environmentally hazardous NOx into harmless nitrogen and water. In addition, the company is testing its system in combination with advanced technologies that reduce particulates dramatically.

The company believes that the increased emphasis on NOx and particulate reduction technologies by U.S. and European environmental regulatory authorities, will provide significant opportunities for commercial exploitation of its patented ammonia injection technology, as the most cost-effective, simple and easily implemented solution to achieving the ambitious goals being set by the EPA and the European Commision.
