Synthetic media in Filter Classes G3 - M5, ISO Coarse, ISO ePM10

SYNFASAN U15 - U50 are outlet-side compressed polyester nonwoven filter media available in Filter Classes G3 - G4 according to EN 779. SYNFASAN is used for coarse dust removal in prefiltration, as a cut-to-size flat panel or as a "Z" pleated filter housed in an exchangeable plastic frame. SYNFASAN is also available in an optional version incorporating a plastic reinforcing grid on the outlet side. SYNFASAN media are environment-friendly products made without bonding agents of any kind.

SYNFASAN C2 - C5G are synthetic-fibre nonwovens compressed on their outlet side to varying degrees of compression, satisfying EN 779 Filter Classes up to M5 / ISO ePM10. SYNFASAN C5G is adhesive-activated for improved dust holding capacity and also incorporates a reinforcing grid. It is ideal for use e.g. as a ceiling filter in application stations for enamels and other coatings.

* : The data given are typical figures. The exact operating data in a specific application may vary in accordance with dust composition as well as other local conditions.
** : Dust holding capacity was measured at the recommended final pressure differential. Depending on the installation configuration and other details of the specific application, filters may be operated to higher or lower final pressure differentials; the dust holding capacity will change accordingly.
