Review:
Works great after 2 years.
(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } I just wanted to let everyone know i bought this unit back in 2018, I am still using it right now. I have not continually used since then but i have used it for approximately 6 or 7 grows through flower for marijuana i have always had it hooked to a carbon filter. I am on my second carbon filter with this unit attached I have it on a timer and i have had it set at all the different speeds this way with no problems. The unit works great and does the job for me moves good air and aids the filter to remove the smell from the very stinky flowers of my marijuana. So 6 or 7 runs now of approximately 2 months give or take a week at 12 hours a day it has been running. Right now im half way through another grow and still doing its job with no issues no extra noise. I have only had good experience with this unit and i would recommend to anyone needing a good 4 inch round duct fan to move air for what ever reason u need. Just hook up a dryer hose and move the air. Very easy to use. Im about to buy another one as i just had another model give out i know this one performs. I will stick with this model.
Vivosun did a full refund
The seller ia trusthworty and refunded because of troubles written here. The fan broke after a few months of usage. At first, I found it kind of loud compared to the exact same one my friend has. Then, a loud rattling sound started and since I was in late bloom, I had no other choice then to open and see what was going on... I thaught it might be a the cage that had been displaced but no, the bearing is the problem. I love vivosun products but for this one, I just can't put a good review. I just ordered a ac infinity 4" fan. I guess I was unlucky with this one...
Best Value For The Money
This is the 3rd 4" fan I have had. Vivosun sells a 4" plastic and a 4" steel with no speed control or wrap. Spend the extra and buy this fan, it's not much more but it is significantly better. It's exhausting a 4x5 tent through a carbon filter, and on the lowest setting it still creates a good amount of negative pressure. This unit is by far the most quiet. It's still about 60db, well above the advertised rating of 41db, but is a significant improvement over the 71db of the next cheapest model. The cheapest, plastic one, was even more noisy, but I don't have a noise measurement.
Very Good Fans I Been Using Them for Years
I use these in my grow tents and they work like a charm. Great value and they don't make too much noise either.
Super strong but very little variability in speed
Bought this fan to vent my 3d printer but there is not enough variability between the highest and lowest setting. Just from vibes it seems like the low setting is still at least 50% of the flow from the high setting, maybe more. The low setting is still too much for my application.
