VEVOR Portable Ventilator, 10 inch Heavy Duty Cylinder Fan with 33ft Duct Hose, 380W Strong Shop Exhaust Blower 1893FM, Industrial Utility Blower for Sucking Dust, Smoke, Smoke Home/Workplace

Don't know but I've work in extreme weather in the Island. And it is resistant, easy to clean as long as you can expand it, so it dries and it doesn't create mosquitos !

Only 1 speed on top

Probably it works. It will depend on wind, location and remember that this equipment is more for construction sight residential or commercial because it has a certain level of sound or noise. Depending of the level of tolerance can be a great addition. To me it wasn't a problem and i still use it for days of air pollution when the electricity shuts down and many people & commercial stores use their generators. So, you have to try in your own situation. Good luck !

I have a 12" x 30' flex pipe, i'm sure it would accomplish the job but it's loud, Real loud! I would not use it, put a box fan in the area.

This fan is not recommended to be used with other regulators, and the wind speed cannot be adjusted at will.

Yes, but it is pretty loud. It moves a lot of air.
