Customer Reviews for VEVOR 4 Inch Inline Duct Fan HVAC Exhaust Blower Kit AC Variable Speed Control

I ordered this Inline Fan for my grow tent, which is the Vevor Brand 5 x 5... the fan is as stated, runs great, quiet, easy to install, the variable spped control works well and is easy to set. My tomatoes, cukes, & peppers are doing great, the fan gives the right amount of air flow needed for this size tent in my opinion. Thanks Vevor for another great product!

Do not know longevity of it yet... but works great so far

I love the versatility of the blower, many ways to mount it or just let it sit, I have a 4x2x5 and it’s does exactly what you need it to do

Great fan. Used in attic to improve air circulation. Easy to mount with provided hardware and easy to disassemble to occasionally clean.

I've used these for air cooled grow lights as well as cold air return on a long stretch of duct work for a forced air furnace. It works great

I've been using this 4" inline duct fan for about 4 days. I've been using it for extracting sublimation fumes to the outside. So far I have noticed much less sublimation ink smell in my 12x12 room home shop. I put it close (8-10" away from my project). It does the job, all in all, it's not that loud and it works great.

Does the nicely. I usually only run it at half power otherwise my grow tent would implode!

Lots of volume. Very low noise. And the price was right. I use it to cool my Crypto miner. Shipping time was reasonable.

The kit works well and exceeds expectations. It's multi function programs allows use for various conditions. The control station is easy to use and is attractive with its LED numbers. The unit is well built and the fan has 10 selectable fan speeds. The only function I don't like is that after the fan is manually turned off at the control station a complete run through all the program functions is required to reach the manual ON position. It would be better if On and OFF could be switched back and forth.

May have asked too much of it but it does its job well. I should probably add a second one for the size of room I’m using it in. It does help move smoke out and keeps fresh air cycling through and helps prevent cigar smoke from leaving the room I’m in.
