Our products

We provide products that increases the energy efficiency and profitability of our customers. Good filtration ensures a sustainable production and contributes to less pollution in the air, water and land. For example, by using the right filter of high quality our customers can:

  • Prolong machines and components life – a high quality filter removes particles and contamination which reduces wear at components and systems.
  • Reduce oil consumption – clean oil does not need to be replaced as often as contaminated oil, with right filtration the oil keeps clean and our customers do not have to make unnecessary oil changes, which save resources.
  • Condition monitoring – we have equipment that monitors the oil. This means that our customers further avoid unnecessary filter changes.
  • Clean air – our filters ensure that the air emitted from, for example industries, is not polluted. We help to clean the air we breathe in.


We do not only work with a product that makes the world more sustainable. We do everything we can to reduce our own impact in different ways.

  • Joint purchasing group for all three countries – we work together to optimize purchases, for example through co-deliveries, fixed weekly deliveries and reduced transport between the companies.
  • We offer our customers flexible logistic solutions. For example, they can get direct delivery from the factory when and where it’s possible. We also offer weekly co-deliveries for big orders.
  • We use Skype as much as possible to reduce unnecessary travels between the companies.
  • Our goal is to reduce the energy and water consumption by installing automatic sensors, low-energy lamps and suchlike arrangements.
