Santa Fe, N.M.-based CleanAIR Systems, manufacturer of emissions control technology for diesel and natural gas engines, was recently granted Level 3 Plus Verification by the California Air Resource Board for the company’s Permit filter.
The designation of “Plus” added to the original product verification certifies that the Permit filter does not increase nitrogen dioxide emissions beyond the 2009 limit of 20 percent over the baseline for stationary engines.
Originally verified five years ago, the Permit filter reduces emissions of diesel particulate matter by greater than 85 percent for prime and emergency generators.
Exposure to nitrogen dioxide can cause serious health issues such as acute lung injury. Unfortunately, many diesel particulate filters on the market increase NO2 while in use. With this in mind, CARB is attempting to limit NO2 emissions with the current ruling and will withdraw verification at the beginning of 2009 if a technology does not meet the specified limit.

CleanAIR Systems has developed and brought to market eleven new technologies to the field of air pollution control, including the company’s proprietary Permit diesel particulate filter characterized by a non-washcoat catalyst. This past June, Caterpillar selected CleanAIR Systems as its strategic alliance partner of choice for emissions control products, supplying retrofit technology for Caterpillar prime and back-up generators.
