Review: Great kit that does the job! - I bought 2 of these kits since I caught one on sale. I do not regret buying either kit. The fan instantly helped me keep my temps and humidity in check in a small room and a 5x5 tent. Even on low the exhaust fan sucks in the walls of my tent (I need to add an inlet fan to fix this). The carbon filter does a great job at keeping the smell down in both the room and the tent. There is literally no smell at all on the other side of the door or tent. The only 2 things I could complain a little about is that the fan is a little loud and they should have included a 3rd hose clamp in the kit. Even on low, there is no way someone is going to walk in a room with your tent and exhaust running and not wonder what the noise is. Overall this is a great kit and well worth the money. Don't expect it to be whisper quiet and pickup an extra 6" hose clamp before you try to install it and I think you'll be very happy with this kit.
Review: Quiet, reliable. - Quiet fan, working well for me so far, adjustable speed works fine with variac speed controller.

### ⭐⭐⭐⭐ Noisy / Not Properly Balanced Impeller/ 4yr Life? New models wt better motor?
*by L***E on June 8, 2025*

I just recently (06/25) replaced the fan unit from this kit that I purchased here on Amazon July 26, 2021. The complete kit was on sale for what is normally the price for just the fan - $59.49. From the beginning, the blower unit showed enough vibration that I couldn't use the included wall mount and had to resort to laying it on a cushioning bag of fiberfill on the top of the grow tent as a vibration damper. I needed the clearance inside the enclosure, so although hanging it may (or may not have) transmitted the vibration from the unit through the frame as badly as it did through the wall bracket, it wasn't an option. Laying on the fiberfill, the noise was reduced to a tolerable level, and the unit ran 24/7 at full RPM for just-a-month-shy of a full 4 years. Running the blower with the intake hose removed the imbalance of the impeller and the amount of deflection from centered was clearly visible. Still, there was enough clearance between the red impeller and the venturi that this did not interfere with the function of the unit. At 195 CFM, it has good suction and air could be felt processing through the filter on the exhaust end. However, starting at the beginning of 2025 the fan suffered from reduced RPM / CFM and sounded strained. I regularly clear the intake impeller of any airborne particulates that might accumulate on the impeller blade edges, so I removed the intake venturi and the white center screw to unmount the blade. The blade itself was free of accumulate. The shaft of the motor, on the other hand, was difficult to turn. The motor in question in my July 2021 model does not look like the current depictions that suggest a multi-field induction or EC motor. I recognize the motor as a variant of the type of small wire wound motor that had been used for decades in household refrigerators to circulate the air in and from the freezer. These motors are ideal in a sub-freezing environment as the motors and bearings are literally cooled by the freezer environment. As such they could run for 10-20 years before the bearings run dry or wear - and even then, I have 'resurrected' many that were seized or binding by re-oiling with lightweight synthetic oil at the bearing endcaps. In the case of the VivoSun motor, it was run in non-refrigerated environment. The bearings were thirsty and did bring back the RPMs upon replenishment, but the imbalanced impeller had also worn the actual sleeved bearing and shaft surfaces so that the amount of deflection, now caused the freely spinning fan to strike the inside of the plenum -resulting in chattering at full speed and dramatic vibration at reduced speeds. I have seen a number of others complain about this fan (even as separate from this complete kit). Unless the manufacturer has corrected the balance issue with the red intake impeller, and replaced the refrigerator evaporator style motor with something more substantial, noise / vibration will be an issue along with potential early replacement. I chose to try a 4" Vevor EC motor fan unit for about the same pricepoint and so far it is immediately quieter with no significant vibration. It also uses less than half (23w) of the power of this one (59w). Since I also have extensive experience with major household appliances using EC motors, I know that the motor control circuitry is a weak point so it will remain to be seen if it will outlast the nearly 4 years life of this unit - but it's already worth it in how quietly it moves its 205CFM vs 195 from this noisier unit.
