Finsa Filtros was founded more than 30 years ago to provide solutions to the filter media market for all dry and wet filtration processes. Finsa has its own weaving plant and manufacturing department equipped with the latest generation looms, quality control machinery and rolls packaging prepared to produce ready-made cloths. Our wide range of standard products is produced in materials such as polypropylene, polyamide, polyester and other special fibres. The types of yarn we use include monofilament, multifilament and staple fibre.

Our philosophy is based on the ongoing development of new products. Finsa is certified under ISO 9001:2000. In our R&D department, we have a filtration laboratory where we simulate the filtration always based on the information we get through the liquid questionnaire.
