Questions and Answers
23 Questions
What type of plug is the 3 pin fan wire that goes to the remote? Is there an extension wire that I can purchase to plug from the fan wire to the remote? All options I see look like screw in connections but the unit does not have room for those.
The product is a three-core cord with an aviation plug. It is not recommended to increase the length of the extension cord as it will cause signal attenuation.
By vevor
What is the longest distance of wires that can be used for controller to still work? How long are the original wires that come with fan? Where can I buy extension wires?
The power cord is 1.8 meters long and the controller cord is 2.5 meters long. Sorry, this is a special aviation terminal plug, which is not sold on the market. We also do not sell extension cords.
By vevor
Can i connect it to the powerful app ipower ? To control it off an on my 8in one has the option..i cant figure out if this one does
The wiring terminals of this product are aviation terminals and may not adapt to other sockets. It is not recommended to replace the plug by yourself.

Super Ventilator
Top Leistung und gute Verarbeitung. Nach einem Monat im Dauerbetrieb immer noch so laufruhig wie am ersten Tag. Aktuell das beste Preis-Leistungs-Verhältnis in seiner Klasse! Versand ging auch wirklich schnell. Alles in allem, kann ich diesen Lüfter nur empfehlen.

Solide und leise, gute Steckverbinder, guter Controller
Für den Preis von ca. 90€ bin ich mit dem Lüfter sehr zufrieden. Die Verarbeitung macht einen guten Eindruck.Auf den Stufen 1+2 ist der Lüfter wirklich sehr leise. Ab Stufe 3 wird es langsam lauter aber noch OK. Die Steuereinheit ist sehr gut verarbeitet, mit einer Metalplatte mit Aufhängern an der Rückseite, gutem Plastik-Gehäuse und guten Knöpfen. Vor allem die Steckverbinder sind gute, haltbare 3-polige Stecker die sehr gut sitzen und bei denen ein Wackelkontakt sehr unwahrscheinlich ist. Andere Hersteller verwenden hier normale 3,5mm-Klinkenstecker wie bei Kopfhörern, die anfälliger für Wackelkontakte sind.Die Lüftergeschwindigkeit kann nur manuell in 10 Stufen eingestellt werden, der Lüfter passt seine Geschwindigkeit also nicht an die Temp./RH an, was ich auch besser so finde, da mehr eigene Kontrolle über die max. Lautstärke.Es können 2 Lüfter an einer Steuereinheit angeschlossen werden, was ich auch gemacht habe. Beide Lüfter laufen dann mit der selben Einstellung. Ab 70%RH Innenfeuchte steuert der Controller bei mir beide Lüfter an. Einer saugt die feuchte Luft raus, der andere saugt Frischluft von draußen rein. Den 2. Lüfter steuere ich aber zusätzlich über eine Hygrosteckdose, die den 2. Lüfter ab 70%RH Außenfeuchte deaktiviert, damit keine feuchtere Luft von draußen rein kommt. Wenn der 2. Lüfter nicht läuft wirddann einfach die (hoffentlich trockenere) Luft aus der Wohnung abgesaugt.Insgesamt bin ich zufrieden, Langzeiterfahrung habe ich noch keine, aber macht alles einen haltbaren Eindruck.

Sehr guter Rohrlüfter für Indoorgrow
Was soll ich sagen, sehr guter Lüfter. Für den Preis unschlagbar. Scheint baugleich zu sein wie die von Mars Hydro und Spider Farmer. Kleiner Tip: Im „ off“ Modus am Display die Menü Taste und die Lef Taste für 5 Sekunden gleichzeitig drücken, dann kann man einen Setup von der Temperatur vornehmen (+9 bis -9). Das Gleiche Spiel nochmal für die Luftfeuchtigkeit.

Top Lüfter
Der Lüfter läuft im Transporter als Abluft. Der Luftaustausch ist sehr leise. Temperatur und Hygro gesteuert ist perfekt.
Wish list Wish list
Works very well even though it is a bit loud.
I installed this fan as an inline duct booster. I had a tight space that this needed to fit in. It would be nice if the mounting brackets did not force the unit to be installed in one way only. This made it difficult and almost impossible to get installed where it had to. When the unit is on it can definitely be heard from around the house. Not much louder than the air conditioning itself but noticeably louder.

Pas encore mis en place
Je tiens a préciser si on regarde la notice qu'il est tout à fait possible de commuté de degrés Fahrenheit à degré celsius contrairement a d'autres commentaires. Mode On + flèche haut et flèche bas maintenu pendant 5 secondes. Il faut faire attention a bien programmer le mode auto et mettre en off des déclencheurs qui ne servent pas selon le besoin. Il est aussi possible de faire des plages comme décrit dans la notice. Il aurait été intéressant que la notice soit traduite en plusieurs langue car j'ai lu beaucoup de commentaires qui disent pas mal de bêtises faute d'avoir compris la notice...Bref, ça m'a l'air d'être un bon produit

Zieht über Kohlenstoff Filter und Verbindungen, zwischen 2 Zelten ( 2x 120x120x200, 8inch gekoppelt unter einander), problemlos die Temperatur aus beiden Zelten raus... Zelte haben immer Unterdruck (Stufe 2) Für Kunststoff, sehr leise.
