It worked good, but when you put the ductwork on it drastically reduces the airflow, almost in half! Without the ductwork is is a great fan. Only thing I can think is that the ductwork has to be fully extended to work better?

Bueno, al momento tiene un buen desempeño ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Werkt zeer goed fijn apparaat geeft veel lucht en zuigt goed af aanrader!............................

Much louder than expected, does move a fair amount of air, but the tube seams to slow it down significantly.

Products IS great but allso noizy but anyway at the workshop IS LOT of noizy stuffs ... But it's fast to assembly abs smells and novely Blow smela from weding out of workshop

The unit itself is ok, with a 10m hose connected doesn't have enough power to collect dust properly when cutting concrete. You either need a bigger unit with more power or use 2 units, one at the front and one at the back of the hose.

A voir dans le temps. Modèle 255w Fonctionne bien , bon débit pour mon usage. Acheté pour évacuer les poussières et fumées de soudage dans un Atelier en sous sol . Selon le placement , évacuation variable. N'empêche pas la pièce d'être polluée mais permet de retrouver une atmosphère respirable en 5-10 min. Plutôt satisfait. Un bémol à noter : Un contre-courant est présent en périphérie du ventilateur. En clair , si on jette de la poussière au dessus de l'entrée , elle part dans l'autre sens ! Le flux n'est pas optimisé donc.

Preiswertes Gerät mit zu erwartender Lautstärke Verwendung : Zur Klimatisierung eines Satteldach-Schlafraumes durch Ansaugen der Warmluft unterhalb der Decke und Transport mittels eines abgehängten Spiralschlauches über ein gekipptes Fenster nach außen. Die Gebläseverluste des Spiralschlauches sind jedoch so erheblich, sodass eine integrierbare Glattrohrkonstruktion mit passender Manschette überlegt werden sollte.

The fan is too powerful for the ducting, even with a short run without any bends the fan ends up blowing out more dust than it pulls in because there is too much resistance building up inside the duct, so the outer edges of the fan blow forwards and the middle area pulls air in. Once you remove the ducting it pulls very well. It's good to place near a window as the fan is very powerful but with the ducting attached its useless since you cannot control the fan speed.

Nice fan unit—moves a ton of air. Unfortunately, the first motor started tripping within the first week, even without an exhaust hose attached. After some back-and-forth with tech support, I expected a replacement fan, but they only sent a replacement motor. That meant I had to completely disassemble the fan to install it. I then tried using the included 33' hose to vent air out of a dusty room. Even with the hose almost perfectly straight on the floor, the motor immediately started overheating and cycling on and off. Good concept, but the fan and hose are a poor match—you can’t realistically use them together.
