Met een maximale luchtstroom van 450 m\u00b3\/u biedt de Q450 28% meer capaciteit \u2014 genoeg voor grote woningen, vrijstaande huizen en panden met extra vertrekken of hoogtes. Het rendement en de geluidsprestaties zijn identiek aan de rest van de Q-serie: uitstekend.<\/p>\n<h2>Voor welke woning is de Q450 geschikt?<\/h2>\n<p>De ComfoAir Q450 is berekend op woningen van circa 250 tot 400 m\u00b2. Heeft u een gemiddeld grote woning tot circa 300 m\u00b2? Dan kan de Q350 al voldoende zijn. De Q450 kiest u wanneer uw woning aan de ruimere kant is, u veel slaapkamers heeft, of u graag extra capaciteitsruimte wilt zodat het systeem nooit op zijn limiet hoeft te draaien \u2014 wat de levensduur en het geluidsniveau ten goede komt.<\/p>\n<p>Voor woningen groter dan 400 m\u00b2 of voor kantoren en utiliteitsgebouwen is de ComfoAir Q600 geschikt.<\/p>\n<h2>Dezelfde kwaliteit, meer capaciteit<\/h2>\n<p>De Q450 deelt zijn kernarchitectuur volledig met de Q350: dezelfde tegenstroom warmtewisselaar, dezelfde EC-motoren, dezelfde filterklassen en hetzelfde automatische zomerbypasssysteem (Climate Switch). Het verschil zit uitsluitend in de ventilatorgrootte en het toerental bij maximale belasting.<\/p>\n<p>Op de normale dagstand draait de Q450 voor een gemiddeld groot huis nog maar op 60\u201370% van zijn maximale capaciteit. Dat is stiller, spaarzamer en zorgt voor een langere technische levensduur. Op nachtstand daalt het geluidsniveau tot minder dan 29 dB(A) \u2014 vergelijkbaar met het zachtste gefluister.<\/p>\n<p>De besturing verloopt via de ComfoSense C touchpanel of via de ComfoConnect 2.0 app op uw smartphone. Daarmee stelt u ventilatiestanden in, ontvangt u filteralarmen en kunt u het systeem op afstand beheren.<\/p>\n<h2>ISDE-subsidie ook voor de Q450<\/h2>\n<p>Net als de Q350 is de ComfoAir Q450 erkend voor ISDE-subsidie. Vraag uw installateur of neem contact met ons op voor de actuele subsidiebedragen. Combineer de subsidie met de jaarlijkse energiebesparing en de terugverdientijd is concreet te berekenen voor uw situatie.<\/p>\n<h2>Onderhoud: halvejaarlijks filters wisselen<\/h2>\n<p>De Q450 werkt met een G4-groffilter voor de afvoerlucht en een F7-fijnfilter voor de toevoerlucht. Zehnder adviseert beide filters twee keer per jaar te vervangen \u2014 een klusje van enkele minuten zonder gereedschap. Vervangende filters zijn bij ons direct leverbaar. Overige onderhoud is minimaal: de warmtewisselaar reinigt zichzelf bij normaal gebruik.<\/p>\n<h2>Technische specificaties<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Maximale capaciteit<\/th>\n<td>450 m\u00b3\/u<\/td>\n<\/tr>\n<tr>\n<th>Warmteterugwinning<\/th>\n<td>\u2265 93% (Eurovent gecertificeerd)<\/td>\n<\/tr>\n<tr>\n<th>Geschikt voor<\/th>\n<td>Woningen ca. 250\u2013400 m\u00b2<\/td>\n<\/tr>\n<tr>\n<th>Filterklassen<\/th>\n<td>G4 (afvoer) + F7 (toevoer)<\/td>\n<\/tr>\n<tr>\n<th>Geluidsniveau<\/th>\n<td>\u2264 29 dB(A) op stand 2<\/td>\n<\/tr>\n<tr>\n<th>Aansluitdiameter<\/th>\n<td>\u00d8 200 mm<\/td>\n<\/tr>\n<tr>\n<th>Zomerbypass<\/th>\n<td>Automatisch (Climate Switch)<\/td>\n<\/tr>\n<tr>\n<th>Besturing<\/th>\n<td>ComfoSense C \/ ComfoConnect 2.0 app<\/td>\n<\/tr>\n<tr>\n<th>Energielabel<\/th>\n<td>A+<\/td>\n<\/tr>\n<tr>\n<th>ISDE-subsidie<\/th>\n<td>Ja, erkend<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Twijfelt u tussen de Q350 en Q450?
