PremAir® Catalyst Unleashes the "Smog Eaters" to Reduce Emissions

With Corporate Average Fuel Economy (CAFE) standards and more stringent emissions regulations looming, we are well-suited to help OEMs gain emissions credits by using our PremAir® product and other sustainable solutions.

As air flows over a vehicle's coated radiator, PremAir catalyzes the reaction that converts ozone into oxygen.

PremAir is a patented catalyst coating that transforms ground level ozone, the main component of smog, into oxygen. As air flows over a vehicle's coated radiator, PremAir catalyzes the reaction that converts ozone into oxygen.This process capitalizes on the large volume of air that passes through a vehicle's radiator.

"PremAir is the first commercial product that destroys harmful, ground-level ozone already in the air," said Nick Leclerc, Product Manager, BASF Corporation. "The California Air Resources Board recognizes PremAir as an effective ozone-reduction strategy and offers credits toward LEV III certification for car makers using the technology."

Ground-level ozone, the main component of smog, is produced when sunlight reacts with emissions from mobile and stationary sources such as cars, trucks, power plants and industrial facilities. Ground-level ozone contributes to serious respiratory problems and is of particular concern to individuals with impaired lung function or asthma.

This technology can yield emissions credits to help achieve LEV III Emissions Regulations. These credits include:

  • Meet lower fleet average emissions requirements
  • Lower emission bin classification
  • Raise emission catalyst system engineering safety factors
  • Reduce Platinum Group Metal (PGM) costs

Our PremAir systems provide a proven solution to help reduce ground-level ozone. With more than three million vehicles on the road using PremAir, BASF is helping car makers deliver cleaner air for a sustainable future.
