An example of an emissions control system using a CleanAIR PERMIT diesel particulate filter installed on a wheel loader in Torreon, Mexico to eliminate black smoke and odors from the exhaust. Notice that there is no dirty black smoke coming from the exhaust filter located on top of the vehicle even though the wheel loader is running at full load. The PERMIT Filter reduces particulate matter, carbon monoxide, and hydrocarbons from diesel emissions when installed on vehicles and stationary engines.
