Functional description
Thefan(1)takesinthe airfromboth sidesviathe coarsedustlter (2)orthe Quattrolter, re-
spectively.Afterpassingthehumidicationdrum,thepuriedairisledtotheairoutletgrill(5)and
distributed in the room.
The unit continuously measures the air humidity in the room with the integrated humidity sensor
andcomparesitwiththesetreferencehumidityvalue.Iftheactualvalue(e.g.40%rh)isbelowthe
referencevalue(e.g.45%rh)thehumidicationdrum(3)startsturning.Thevaporizermatisdipped
intothebasetub(4)andtakesupwater.Theairpassingthroughthehumidicationdrumabsorbs
the humidity.
Thecoarsedustlterretainsdustparticlesupto100µm.IftheDefensorPH28/PH28Aisequipped
withaQuattrolteritcanretaindustparticlesupto0.1µm.Inadditiontheactivatedcharcoallayer
intheQuattrolterremovesunpleasantodour.
Thewaterlevelinthebasetubismonitoredbythelevelregulatingvalveinthewatertank(Defensor
PH28)orbythelevelcontrolledinletvalve(DefensorPH28A).
