De diffusor bevindt zich in de filtertank en verdeelt het water gelijkmatig over het filterbed, waardoor optimale filterprestaties worden gegarandeerd en kanaalvorming door het zandmedium wordt voorkomen. Hij is vervaardigd uit duurzaam, chemisch bestendig kunststof (PVC\/PP) voor een lange levensduur in zwembadwateromgevingen.<\/p>\n<h3>Compatibiliteit<\/h3>\n<p>Deze diffusor is uitsluitend ontworpen voor het AstralPool Aster-zandfilter met een tankdiameter van 650 mm, geschikt voor zwembaden van 80\u2013120 m\u00b3 in combinatie met pompen van 1 HP tot 1,5 HP. Deze is niet uitwisselbaar met andere Aster-diameters (bijv. D.350, D.450, D.750, D.900) of andere AstralPool-filterseries. Controleer altijd het model van uw filter voordat u bestelt.<\/p>\n<h3>Waarom authenticiteit belangrijk is<\/h3>\n<p>Als een in de fabriek afgestemd OEM-onderdeel, is deze diffusor nauwkeurig gevormd volgens de exacte inwendige afmetingen van de Aster D.650-tank, wat zorgt voor een correcte afdichting, een gelijkmatige waterverdeling en volledige compatibiliteit met de maximale werkdruk van het filter van 2,5 kg\/cm\u00b2 en de filtratiesnelheid van 50 m\u00b3\/h\/m\u00b2. Alternatieve onderdelen uit de aftermarket voldoen mogelijk niet aan deze toleranties, wat kan leiden tot een verminderde filtereffici\u00ebntie of voortijdige uitval.<\/p>\n<h3>Installatie<\/h3>\n<p>De diffusoreenheid past in de filterbehuizing en is toegankelijk zodra het schroefloze, snel te openen deksel van de Aster is verwijderd. Zorg ervoor dat het filter volledig drukloos en leeg is voordat u de diffusor vervangt. Hoewel het gereedschaploze dekselontwerp van de Aster de toegang vereenvoudigt, is een juiste uitlijning van de diffusor in de tank essentieel voor een goede werking \u2014 bij twijfel wordt professionele installatie aanbevolen.<\/p>","protected":false},"excerpt":{"rendered":"<p>AstralPool &#8211; diffuser assembly for Aster d.650 sand filter This is the genuine AstralPool replacement diffuser assembly designed specifically for the Aster D.650 laminated sand filter.
