VIVOSUN Inline Booster Duct Fan 8” 430 CFM with Speed Controller, HVAC Exhaust Ventilation Fan with Low Noise for Basements, Bathrooms, Kitchens, Attics, Grow Tents

Very happy with this product. I installed it into a green house connected to a thermostat and ran the supply off of a HVAC leg. With the air hepa filtered on the unit and the house temp at a constant 70/71, when it calls for cooling the fan pulls that extra air in with the adjustable speed and power to move cool air in. Easy to install, works great, and Vivosun Quality as always.

This exhaust fan works great. I have had it and tested it for over a month now. It is very quiet, I wish bathroom motors were this quiet, next the power dial also controls the speed of the fan. the fan speed is completely adjustable this is a HUGE bonus. Most air duct exhaust fans are either on or off, this one has fan speed control. It hooks up pretty easy the length of the cord is about 6 feet which is good. The on off switch is the dial, so the only negative is the switch position. I wish the switch was closer to the outlet and further away from the actual inline booster module.

Ive bought several of these, they work well and move air but some of the controls die after a few days of continuous use. If hardwiring the fans work great

Awesome little inline fan. Used two years so far without an issue

Vivosun is a great company to deal with. Awesome customer support. I installed this in my dryer exhaust line and it has sped up my dry time. Fan runs quiet and every efficient. Can’t go wrong with this product.

Has not even lasted a year. It was only being used for a few months in the summer/ fall. Only running periodically. Now it won't spin. There is power, but the motor has died.

The fan looks good, fits great, and works. However the speed adjustment does very little to adjust the fan speed. It clicks on to "low" and when turned up just a bit the fan gets faster. But, just above "low" all the way to "hi" the adjustment doesn't do anything, the fan stays the same speed. So, it basically has two speeds, low and hi. It's just a booster fan so I expect I'll always have it on "hi" but I expected a little better adjustment.

I ordered a eight inch duct fan to help heat my shop. My shop is an added on single garage to the double garage of our house. The double garage is heated but my single garage is not so l cut an eight inch hole in the wall between the two and installed the fan as close to the ceiling as possible to capture the warm air in the heated garage and blow it into the shop. The fan came with a speed control which really was a plus. It works great but is a little noisy.

It’s been running for 2 years in a hostile environment with no help or maintenance. For the price, it does just fine. And it’s practically silent.

Se ve y se siente la calidad en los materiales, hace muy poco ruido a maxima potencia aunque me hubiera gustado que tuviera más potencia pero cumple.

Llegó en mal estado, su forma es redonda y llegó ovalado...

A mi me funciona como "inyector" de aire a la carpa y complemento con un extractor en la parte superior. Funciona mejor para ventilar y no para extraer. Ventajas es que tiene 2 niveles de operación, es ligero y puedes colgarlo. Puede adaptarse un tubo e inyectar aire a la carpa o puedes ponerlo directo en la entrada de la carpa si tienes las entradas con el tamaño adecuado. Fíjate bien antes de comprar que diámetro tienen tus entradas de aire. Estaría muy bien que incluyeran algún tipo de colgante o abrazaderas. Por lo demás cumple

No soporta el calor
