Seltek Oy was originally started in 1956 and has worked ever since mainly in the pulp and paper industry. It all started around a patent for the material on a suction cover box. Later Seltek started to represent various companies in the pulp and paper industry and focused on the Finnish pulp and paper market.

Among others, Seltek represented Ronningen–Petter® Filters systems for many years with great success. For several years Seltek was among the top 5 sales representatives worldwide

Seltek Oy specialises in liquid filtration systems for all kind of liquids. From simple raw water applications to high viscous colour coatings, there are good solutions for every application. The aim is to offer filter systems that automatically regenerate the surface, guaranteeing a minimum amount of waste. Only unusable material is removed and gently taken from the process.

White water, wet end chemicals and surface treatments can be protected with our filters systems, ensuring the quality of your final product is as expected.

After spending 30+ years in liquid filtration we have a good experience base and knowledge on applications and dare to call ourselves specialists in this field. There are not a lot of applications we have not seen and we would be happy to suggestion how to solve a filtration challenge.
