Price Guide: POA


  • Air Shield™ Diesel Exhaust Fluid is compatible with all on- and off-highway SCR systems, Air Shield DEF is API- and AdBlue®-certified.
  • Air Shield enables on-highway diesel engines to meet the EPA's near-zero NOx emission levels required for
  • 2010 and later on-highway diesel engines.
  • The SCR systems work by injecting DEF into the engine exhaust, creating ammonia which then flows through a SCR catalyst and reacts to form harmless nitrogen and water vapour.
