Our company following closely the market trends, presents its completed on line catalogue through its webpage. In addition to the cross reference part, already available for the past three years, the user can find through the application catalogue or the dimension charts the filter that he is looking for. Regular customers can use their personal electronic pass and browse further, checking on availability, variety of choices or even book their future needs. We strongly believe that this is a useful tool for cooping with the ever increasing difficulties in filter finding. Your opinion, prepositions and corrections in omissions or possible mistakes is welcome.
