VEVOR Portable Utility Blower Fan, 12 Inch 585W 3198 CFM Heavy Duty Cylinder Axial Exhaust Fan with 33ft Duct Hose, Industrial Ventilator for Ventilating Workshops, Confined Space

This unit is a tremendous value. I bought it for bringing air into my crawl space while i was doing a bunch of work in there. It's rather loud, but it moves the air! The slinky hose is really high quality and better than I expected. If you need to bring in fresh air into a confined space or similar area, this unit is terrific.

A very good buy for the price, purchased to ventilate confined spaces and it really moves the air!

I work with a lot of demo and drywalls so this was the perfect addition to team to get all the excess dust out of the home that we are working at.

I read all the reviews, and almost passed on this blower. However the price was right, and if I had back luck, I could send it back. Here is what I found. Packaging / damage: Duct was double boxed, and the blower was padded with EPS foam blocks. Arrived with no damage, and a nice paint finish. Duct: The duct is actually half the weight of the whole (heavy) package. Adequate materials, good spring, should last a while. Blower Housing: Real Steel, good welds, decent handle, hardware is tight, but check and re-tighten as needed. FAN: made of substantial polymer, and balanced. Six blades, turn at high speed. Yes, it blows the correct direction now. Cord: heavy cord about six feet long. It has a strain relief molded into it. The strain relief is held by a steel plate, and won't come out, under normal use. The plug incorporates a safety contactor. You must reset the contactor each time you plug the blower into electricity. If the power is interrupted, while running, the fan will not just restart when the power is restored. You must push the reset after the power is restored. I think, but do not know, it may also be a GFCI (?). Motor: The motor may be the weak link. It is physically small , and takes some time to get the fan up to full speed. This kind of motor is known as "Air Over". That means the air the fan moves, also cools the motor. Result is, you cannot restrict the air flow. If you do, the motor will overheat. I hope it has a thermal protection switch, but I did not look for it. Performance: The blower by itself, moves some high velocity air. You could use it as a leaf blower. Air Volume is pretty good without the hose. The static pressure could be higher however. When you add the hose, the air volume goes down significantly. I bought the long hose, but buy the short hose if it suits your purpose, because more air moves through a shorter hose. Keep the hose as short and straight as possible. I do not think the motor is totally enclosed, so using this as a dust blower will reduce its life. There are fan guards at both ends of the blower, but small pebbles cold get sucked through them, and damage the fan blades. Outside, maybe put it on a square of plywood, rather than the ground. Main Question is, how long will the motor last, because everything else seems solid. Oh, and yes, it is loud. Not unexpectedly loud, because it is a high speed fan / blower. Putting the duct on it helps a little.

Big fan, big air movement. Does exactly what I baught it for! Well made. Got some heft too it. Seems like it will last a long time. 10/10 happy with my purchase.

This fan it pretty bad at everything it does.1. it blows air at the edges of its body at the intake. This results in some heavy air turbulence, and a very unclean environment.2. it randomly shuts off, and will turn back on after a while.3. the ducting blows off easily, and MUST be taped on.4. it is loud, and has bad motor whine.

I love the Vevor brand in general, but this fan, yall better hold on to your hat! This fan is the fan of all fans. I purchased it to vent my greenhouse and it does an excellent job. Keeps you cool and it must weigh 20lbs. It's very well made and I expect it to last for years to come. It is a little loud.

Very powerful, weighty, solid, reliable fan. The plug is hefty and high-quality, the motor is very solid and impressive, and the duct is thick and durable. This will definitely get air in or out of wherever you need it. The only downside is the noise since there is no speed adjustment. So, if you think you could settle for a smaller fan, definitely go with that instead, since this may be difficult to use in your house or business (even in low-key emergencies) since it's so loud. I would save this more for large, stinky painting projects, construction, water damage remediation, and temporary warehouse air circulation. And, as a side note, it looks super cool to have the duct sticking out of a building piping air out.
