Copia Clay CP Jet 100 30/60 and CP Jet 100 B 16/30 have proven to be effective in the refining process of ATF. These granulated Attapulgite based clay minerals are specially processed to attain a low moisture level of below 3%, which helps in the removal of traces of water, surfactants and other impurities. ATF treated with Copia clay granules ensures that the aviation turbine fuels so processed meet international standard specifications.
