CARB approves use of filter

Clean Air Partners (CAP) offers the only catalytic particulate filter for natural gas engines approved by the California Air Resources Board (CARB). This filter reduces CAP's Dual-Fuel engine particulate matter emissions to 0.006 grams per brake horsepower-hour — 40% below the EPA's emission standards for 2007.

CAP Dual-Fuel engines do not require ultra-low sulfur diesel. The CAP catalytic particulate filter also reduces emissions of aldehydes, non-methane hydrocarbons, and carbon monoxide.
