Seriously moves some air. I rigged this into a bathroom window since my apartment doesn't have a proper vent system. It moves so much air I can vent specific rooms by just cracking a window in there and flipping it on in the bathroom, which is on the other side of the apartment. I routinely use it to clear the air in my kitchen which is around two corners.

Stabiler Lüfter, läuft sehr leise und hat eine gute Luftleistung, habe ihn auf meiner Terrasse verbaut. Einzig das Anschlusskabel könnte etwas länger sein, ist ca. 25cm, 1m wäre hilfreich.

Easy to mount, mounting holes too big. Had to use fender washers. Very quiet and moves alot of air. Will work great for generator my enclosure.

Genau das haben wir gesucht, passt super in die Veranda. Vielen Dank

Super Service

Very powerful! Keep in mind you must do the wiring yourself

Buen material , se ve de calidad con gran potencia de extracion. En verano veremos si baja la temperatura del tejado.

great fan well built moves a lot of air . Make sure you don’t bind it when you mount it aka cut hole to small

I installed this fan in the wall of my generator shed to remove the hot air (not exhaust gas). Plugged it in to the generator so it runs when the generator runs. I had a little problem with the louvers not working smoothly, until I found out that my un-square opening was putting the fan frame in a bind. After I squared the opening, the louvers worked properly. They move so freely now that I have to tape them shut so they don't flutter in a breeze when the genny is not on. My only gripe is the 8\" cord left sticking out of the makeup box. I could have put a cord cap on it and used an extension cord for power, but I avoid using extension cords whenever possible. I cut the female end off a computer power cord and re-made the joints in the makeup box. Clean now, and complies with the NEC for having a disconnecting means nearby. The fan can mount from either the inside or outside. I mounted it from the inside, so all I had to do was caulk the top of the penetration.

I installed two of these in steel doors to cool a generator. They draw about 100W each, they are reasonably quiet when running (you can have a conversation at normal level right in front). The quality is good, shipping boxes are well thought out and protect them well in transit. The only thing I would mention is sudden changes in pressure (like the wind gusting) can cause the closed louvers to open and close, making some noise. Overall I am very pleased.
