SUNMAX RT900A 3-Speed Air Mover 1.3HP 5000 CFM Powerful Floor Blower Carpet Dryers Janitoral Floor Dryer with Telescopic Handle, Wheels

It is amazing! Its not terribly loud at all, but definitely not a sleeping fan lol It moves air like its nobody's business on the LOWEST SETTING, the highest setting had the room feeling like a wind tunnel. Best purchase i have made in a very long time, well worth the money especially on the hot days that we've been having in the Midwest. The power of the fan is phenomenal, it literally has recoil if you pick it up while its on lol. The size is somewhat expected as its moving a lot of air very quickly. The weight is on the heavier side so definitely dont lift with your back when moving it unless you use the wheels it has preattached. It feels very durable with a hard shell so it won't crack easily. Overall a 10/10 purchase, would buy another but 1 is all you really need lol

This is GREAT! we use it to ventilate semi-trailers for loading. Moves TONS of air. Works so good.

Work perfectly fine for what I need it. Strong blowers, it's loud if you want something not too loud don't get this fan. It's cheap in comparison with other name brand blowers works amazing, it's super good.

Bought this for use as the prime mover for an educational wind tunnel. I own many types of anemometers and as a mechanical engineer I can do the math. At the highest speed setting, the peak air velocity (at the center of the outlet nozzle) was 98 ft/s. The average velocity over the 4" x 14" area of the outlet nozzle was about 80 ft/s, (and by the way I'm at about 500 ft above sea level.) That translates to about 1870 cubic feet per minute, which is less than the claimed 5000 CFM rating by a factor of about 2.7. This was not a surprise to me, because given a 1.3 horsepower motor (which this blower does indeed have), even a perfectly efficient blower (which does not exist) could only possibly push up to about 2700 CFM out of an opening that size, at sea level. There's just no realistic way to get even close to the rated CFM out of a machine like this, except possibly by ducting the outlet back to the inlet via some kind of ingeniously designed diffuser/duct arrangement. But not to worry - ALL of the manufacturers of similar blowers lie, by roughly the same factor. Probably because they all use the same bullsh** formula based on the rated RPM of the motor and the size and blade pitch of the impeller, which in no way reflects the real air flow rate. So at least compared to other blowers on the market, the CFM rating is in some sense reasonable, which is why I'm still giving it four stars. This blower does seem to be one of the best values out there in terms of power vs price, and it functions reliably.

Pure constant wind! We use it in the shop and it moves more air than any fan. With temps well into the 90s and humidity that just makes you feel like a slug this monster air mover really does the job!
