6 inch inline fan with speed controller

The fan comes with a controller and a plug in temp sensor. Power goes to the fan via the 3 pin plug then the controller can be placed approx 2 mtrs away and the temp sensor another 1.5 mtrs if needed. The fan has 10 speeds and the controller ramps up the speed in steps so keeps the current draw low. The ‘auto’ setting wasn’t quite as automatic as I’d hoped as in it won’t vary the fan speed to suit the temperature set point. Instead you pre-select the desired speed setting and the controller turns the fan on/off according to the temp or humidity set points. You can give it maximum and minimum set points to run the fan within so it’s quite flexible, will take a bit of trial and error playing with the settings but it will make sense (note you have to put a value against each one of the high/low temp and high/low humidity before the controller is ready to take over (those parameters flash at you indicating they need attention) I am not tech savvy but managed it fine. The fan itself is well put together and can be easily split away from the casing and withdrawn without disturbing the ducting either side. Fan is quiet and doesn’t vibrate at all, on speed 10 the air noise is more pronounced.

The fan and controller are good quality and the fan is well balanced. The only problem I have (which is a fairly big problem) is that at slower speeds (below half) it emits a very loud hight pitched whistle that makes it unusable to have on at night. Edit* The high pitched whistle was the alarm letting me know the temp probe wasn't connected! Once connected it was completely silent and worked brilliantly. Uprated to 5*

The product broke after 6 months of use several days a week for several hours at a time to extract fumes from my laser. I have ordered another of the same but can find no way of contacting the supplier to resolve this issue. Worked well when it worked. The new model is much quieter and more refined then the previous. Thank you for quickly responding.

I use it for a laser cutter as an extractor fan, and so far it works pretty well. Easy to access for the impellers to clean off the dust, very quiet, yet strong enough to eliminate all of the smoke. I can recommend this product if the extractor have to remain in the same room as the working area. The adjustable switch is a real plus.

We tried this with no other noise in a cellar at night in the countryside which is as close to silent as you get. It sounds like a jet engine. You can hear it two floors up. You can see that on the photos. Both watches measure the same. It is a fan and seems to work as a fan. But it is absolutely not quiet in any way! Returning as NOT as advertised. Well over 100db not 32db as advertised. Waste of my time.

Good quality and quiet keeping me cool will be back

Bought the 6" model and generally pleased. It is noisier than hoped buti have mine suspended from the bracket rather than mounted to something solid which mitigates noise a bit. Even at low speeds it is moving plenty of air. Speed control is a little slow to respond but works well. Would be nicer if it gave rough rpm levels. Lead to the speed control is a stingy 1.5m. Power lead also stingy at 1m.

nice fan for the price shame the adjuster was not wireless but its works fine and does what its meant to do

Das Teil schockt komplett Hammer Leistung zudem ist das Programmieren ein Kinderspiel ! Ganz im Gegensatz zu dem was einige schreiben ist die Bedienung ein Kinderspiel ! Ich bin so sehr überzeugt für Meine GrowBox 1,20mx1,20m Mehr als der Hammer gäbe es ne Nummer Kleiner würde die es mit Sicherheit auch tun. Für die Steuerung per Handy für eine einfache Einrichtung einfach die App Smart Life herunterladen. Der Rest ist selbst erklärend in der App ist allerdings keine Möglichkeit von Fahrenheit auf Celsius zu stellen aber das ist ja nicht wirklich von Bedeutung. Alles lässt sich dadurch Steuern sowie überwachen überprüfen. Einfach und Genial. Der Monitor sowie der Lüfter sind von höchster Qualität ! Monitor kann man übrigens in Celsius umstellen ohne Probleme ! Bedienungsanleitung ist in gutem deutsch übersetzt! Ich hoffe ich konnte Helfen! Absolute KAUFEMPFEHLUNG !

Tengo un pequeño huerto en casa de hidroponía y en las etapas de invierno cuando hay que mantener la temperatura dentro, propongo en un armario diseñado para esto de buen tamaño y este extractor de aire funciona de maravilla, ya que puede tomar decisiones prácticamente por sí mismo. Por ejemplo, lo he programado para que a cierto, nivel de humedad empieza a funcionar. aunque también en fechas de altas temperaturas, lo he programado para que a cierta temperatura comience a funcionar. En general, estoy sumamente satisfecho con la calidad de este extractor, y no dudaré ni un solo momento en hacerme de un segundo

This device moves a lot of air, and it still reasonable quit. I'm using it together with my CO2 laser to remove the smoke out of my Garage.

Très puissant c'était le but recherché, je l'utilise pour amener l'air chaud de mon poêle au pellet de ma pièce bas vers ma pièce à l'étage. Seul point faible il est assez bruyant.

ممتازة جدًا وعملية 👍 وصلتني من بريطانيا إلى السعودية في غضون 4 أيام!.
