K..P.A.F is introducing innovations in the field of HEPA filters. Using state-of-the-art technology K.P.A.F not only supply conventional HEPA filters but also extended surface HEPA filters, manufactured for a flow rate of 3600 m3/h at an initial resistance of 250 Pa, for example. Depending on the application, we can deliver these filters with efficiencies from 95% to 99.99996% (as per the NaCI test, Eurovent standard 4/4 and DOP test). K.P.A.F. can supply the filters for all makes and applications.
