VEVORIndustrial Portable Air Blower Ventilator with Hose, 3198CFM 12 Inch Heavy Duty Tube Exhaust Fan with 33ft Flexible Duct, 585W High Velocity Air Mover for Extraction and Ventilation

From reading prior reviews, I thought: 1) it's going to be REALLY loud, and 2) the duct is probably going to last only a short time. Well, it was no louder than my Hoover upright vacuum cleaner. I've only used it once, so time will tell regarding durability, but it is definitely well built without flimsy materials. When I pulled it out of the box, I noticed immediately that the duct was HEAVY, and appears to be well made of a durable material; in addition, to attach it to the fan, it has a thick nylon cinch cord. So far, it LOOKS like it'll go the distance. And,most importantly, it does move a lot of air.

This is a great product made of superior quality. It's durable and very powerful. If you're a contractor working on indoor projects that generate a lot of dust, or if you're serious about removing dust from your home, this product could be exactly what you need. Unfortunately, I found it a bit bulky and noisy for my needs, so I had to return it and opt for a lighter, quieter, albeit less effective alternative for cleaning my basement.

For it's size it a monster. I had a water leak. This was for the crawlspace under the house. I hoped to move a lot of air. The duct directed the air where I want. But you need everything secure because the airflow is wild. Secure the duct. It can expand and move wildly with the air.This moves a lot of air. You could ventilate an entire tunnel under a border with one or two of these.It's small but heavy. Everything is thick, sturdy, and simple.I bought this in an emergency to move a lot of air. Hopefully that will be fixed and I'll find some other purpose for this since it works so well. Not sure what since it has only one speed, fast. Too much to stand in front of, and consider small animals that walk behind it.

I use this fan to vent smoke from two laser cutters through a 40 foot long horizontal air duct out of the back of our shop. It does a really good job! It pulls the smoke out of the lasers very quickly, and there's no smoke smell, even when I open the door immediately after cutting.My only complaint is that they literally used nothing but twist caps to connect the fan to the main power cord internally. Needless to say, it's fragile. One gentle tug ripped all but 1 wire out of their caps. I had to disassemble the fan and solder it back together. So I give them a 1 star for durability. But aside from that, the fan is amazing.

AS EXPECTED THESE FANS MOVE AN ENORMOUS AMOUNT OF AIR, BE SURE THERE ARE NO SMALL DOGS OR CHILDREN NEAR IT LESSEN THEY GET SUCKED INTO THE INTAKE LIKE A JET ENGINE;). These things are very noise but thats what it takes to move a lot of air, not for a library🤣

Very impressive how much air this moves. The air flow on the one I received was in the correct direction. 5/1/25

Love it. Sucks and blows better than your moms vacuum

I bought 2 units it was all perfect for about 2wks andI'm not sure why, but it would just shut off. Not tripping a breaker or anything, then run for a few minutes then off. I tried several different circuits and got the same result each time.
