What is the difference between Model #3733 and Model #B20201? The specs are the same for both. ...

Asked by SmokeyDaze September 13, 2020
1
Answer

The specs are not exactly the same. There is one spec that is the most important one in box fans and that is CFM. Cubic feet of air moved in a minute. B20201 has a CFM of 1320 while 3733 has a CFM of 1820 a huge difference. The model 3733 also uses less wattage to produce the same result. The main giveaway as best I can tell is that the 3733 is the newer model of the same fan. The giveaway is in the weight the 3733 is 1.65 lbs. heavier than the B20201 and since the cases and fans look exact the difference must be in the motor, i.e. producing more CFM at the same selling price. The 3733 will probably be noisier due to the higher fan speed but if you want to move air the higher the CFM the better. I have this on my workbench in the garage and this thing moves a lot of air for it's size. Have to turn speed down a lot of times to keep stuff from blowing of the bench.

Asked by pc July 20, 2019

Answers

It's a three speed fan, so should actually give 3 numbers for air flow. So 2,500 cfm should be the max or Hi setting, but is the 1820 cfm the low or medium setting??

Does this fan have a fused safety plug?

Asked by Fan July 18, 2019

Answers

no. just standard 2 prong - so it is not grounded. But mostly plastic housing, so pretty safe.

I had an old unit same brand and it looks like same model but the new one has less air flow in each of the 3 speeds and it is in comparison a little thinner.

Good air movement, but blades warped and got brittle over time
I bought one of these in summer 2015 and it worked without bugs for 4 years, at which time one of the blades warped and hit the rear frame, making a clicking noise at startup until centrifugal force straightened it out. That was OK for awhile, but by the next summer (2020) the plastic was very brittle and the blades snapped almost like potato chips when touched. Bad batch of plastic or typical? I'll probably just buy a new blade to not waste a working motor. I recommend it because it didn't cost much and the sound isn't unpleasant.

I noticed one blade cracked and broken within 30 days. The only possible trigger I could think of was it fell down to carpet floor once.

Quick to install and reasonably quiet. We installed 10 of these in our barn. The stalls are 12'x24' and they move the air great. There's a "hum" when they are running, but it's not near what I had expected when they are all turned on.

Blows over backwards when on high speed
Quality :

I cannot believe that this fan got so many good reviews. When I plugged it in and turned it to high, it immediately blew over backwards. I was able to fashion a rotating brace which I attached to the bottom after taking off the rear screen and drilling a hole, but don't feel that I should have had to do this. I will keep it as it will suffice for my needs and the price was right, but it was sure not designed very well.

The fan is definitely effective, but can be a bit loud at time depending upon the surface it's placed on. On the floor I didn't notice much in the way of noise, but on a table it can be an issue. Overall a good fan if you're looking to save some money by not using your AC (or cooler) all the time.

While this fan does a good job of moving air, and is about as loud as you'd expect, it will not stay in place. I have hardwood floors which are from 1950 and so they aren't perfectly even or level, but are very smooth since we had them professionally re-done when we moved in. I installed the "slip-resistant" plastic feet (see attached photo) and they most certainly are not slip-resistant. They are hard, smooth plastic, and the fan has enough vibration on any setting that it just jitters all over the floor. At one point it found itself over against a wall, and start vibrating against that making noise. I temporarily stopped all this by placing some cheap adhesive weatherstripping to the feet (front and back), but after about an hour it must've made the unit off balance since it start wobbling on any speed. I remove the stripping but then it was back to sliding all over the floor again. All they need to do is put a coating of rubber on the front, thin plastic feet, and on the contact patch of the rear feet (for which I'd gladly pay an extra $5 on the price) and this fan wouldn't move on any surface. Also, the steel frame is so thin that if the fan is on a slightly uneven surface, it starts to wobble (the frame itself.) Even more so on higher speeds to the point where it seemed like it might tip itself over. If you have carpet, or plan to use a window to hold it in place on a sill, you'd probably be fine, and I'm sure it would work great for the price. However, DO NOT buy this if you intend to use it on a hard surface, or it won't stay still and may risk tipping over (which I've seen in other reviews can snap off the blades if it falls hard enough.) The materials all just seem super thin and cheap to save on cost, whereas box fans I remember using growing up (80's) were of thicker steel around the case, and heavier-duty.
