The mobiclean R system provides emission reductions of diesel particulate matter by at least 85% and is designated as a California Level 3 Plus system. It can be applied to diesel engines from 3.4 to 16 liters (100 to 600 horsepower) in any type of on-road applications. Temperature requirements are 392 degrees for 15% of the time in a duty cycle.

Hug DPFs are compliant with both U.S. EPA and CARB requirements to provide maximum PM emission reductions for a wide range of on-road diesel applications. This allows Hug to immediately market and install systems to support California and U.S. fleet regulations and air quality improvement efforts.

The product, with its CleanCoat coating material, does not require any filter cleaning due to its self-cleaning capabilities, according to the company.
