See How the CleanAIR PERMIT Filter Works

View the CleanAIR PERMIT Filter at work as it reduces diesel emissions of particulate matter by greater than 85%, and reduces hydrocarbons and carbon monoxide by up to 99% on off-road diesel vehicles. The PERMIT Filter is individually customized for each application and can be designed as a filter/muffler emissions control system taking the place of a standard muffler. Diesel retrofits using particulate filters can substantially reduce toxic air pollution emissions at a construction site or mining facility.

The CARB Verified CleanAIR PERMIT Diesel Particulate Filter

Animation showing the CleanAIR PERMIT Filter/Silencer reducing back-up generator emissions using PERMIT diesel particulate filters. The PERMIT Filter is CARB verified - Level 3, for emergency and prime power stationary diesel engines to reduce particulate matter by greater than 85 percent. It also reduces hydrocarbons and carbon monoxide by up to 99 percent. The CleanAIR PERMIT Filter/Silencer with the CleanAIR HiBACK Data Logger and Alarm System is a complete air pollution control system for stationary generators.

The ENDURE SCR Catalyst (Selective Catalytic Reduction) for SCR Control

Animation of CleanAIR Systems' ENDURE SCR Catalyst as it dramatically reduces NOx emissions by up to 95% using selective catalytic reduction. The ENDURE SCR Catalyst is designed for use with lean burn engines, gas turbines and fossil-fueled power plants (coal-fired). The ENDURE SCR Catalyst is also available as replacement panels for existing installations.
