Filters
EN3 generally requires a filter when using aqueous extinguishing media.
Our filters are assembled between the nozzle and the pistol (on pistol lines) or between nozzle and adaptor (on open hose lines) so that a diptube filter is not necessary.
In combination with our patented short foam nozzle (S-SCRO-KU-...) the duration of operation will be increased by about 4 seconds, whereby a higher A-rating can be reached.
The free cross-sectional area should be calculated according to the EN3.
| D | S | B | free sectional area | material | item number |
|---|---|---|---|---|---|
| 14 | 0,25 | 0,4x0,4 | 58,2 mm² | stainless steel | D-SIEB-AN |
| 15 | 0,3 | 0,8x0,8 | 93,4 mm² | stainless steel | D-SIEB-15 |
