De diffusor verdeelt het binnenkomende water gelijkmatig over het filterbed, wat zorgt voor een effici\u00ebnte, gelijkmatige filtratie en het ontstaan van kanalen door het zand of glasmedium voorkomt. Het is de directe OEM-vervanging wanneer het originele onderdeel barst, kromtrekt of beschadigd raakt.<\/p>\n<h3>Compatibiliteit<\/h3>\n<p>Deze diffusor is speciaal ontworpen voor de AstralPool Aster-serie zandfilters met een tankdiameter van 450 mm (\u00d8450). De Aster-filterserie is verkrijgbaar in verschillende diameters \u2014 controleer altijd de tankdiameter van uw filter voordat u bestelt, aangezien diffusoren specifiek voor een bepaalde diameter zijn en niet onderling uitwisselbaar zijn tussen verschillende maten. Raadpleeg bij twijfel het etiket op uw filtertank of de installatiehandleiding.<\/p>\n<h3>Waarom authenticiteit belangrijk is<\/h3>\n<p>Het gebruik van een origineel AstralPool-onderdeel garandeert een nauwkeurige pasvorm in de filtertank, waardoor de juiste stromingsdynamiek en de maximale werkdruk van maximaal 2,5 kg\/cm\u00b2 behouden blijven. Niet-originele onderdelen van de diffusor kunnen de filtereffici\u00ebntie aantasten, de helderheid van het water verminderen en het risico op voortijdige uitval van de omliggende filteronderdelen vergroten. Als OEM-onderdeel dat rechtstreeks afkomstig is van AstralPool (Fluidra), voldoet deze assemblage aan alle originele fabriekstoleranties.<\/p>\n<h3>Installatie<\/h3>\n<p>Voor het vervangen van de diffusoreenheid moet de filtertank worden leeggepompt en moeten de meerwegklep en het tankdeksel worden verwijderd, voordat de interne onderdelen toegankelijk worden. Het onderdeel is ontworpen voor een nauwkeurige, gereedschapsvriendelijke installatie volgens de technische normen van AstralPool. Professionele installatie door een gekwalificeerde zwembadtechnicus wordt aanbevolen om een correcte hermontage en een waterdichte afdichting te garanderen.<\/p>","protected":false},"excerpt":{"rendered":"<p>AstralPool &#8211; diffuser assembly for Aster sand filter \u00d8450 mm This genuine AstralPool diffuser assembly is the factory-original internal spare part for the Aster laminated sand filter with a 450 mm tank diameter.
