Step Filters System uses our knowledge added to the manufacture partners, through our experience and efficiency in choosing among all of them the best solution for each application or need.

ISO 9001 and/or TS16949 are quality standards usually requested to become an OE supplier. These standards are also needed in order to be a Step Filters manufacture partner. So we always look for manufactures able to fit our quality production needs.

These are some of the tests we usually carry out:
  1. Oil filters flow resistance - ISO 4548/1.
  2. Fuel filters water-separation efficiency - ISO 4020.
  3. Fuel filters filtration efficiency relating to particles counting - ISO 19438.
  4. Porousness of the media.
  5. Gaskets, media, adhesives, etc. damage or ageing.
