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.

Works well. Tight fit on 6” pipe but does fit. Simple to use. Good price.

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.

We are using this in our sauna wall to vent out and it works great, moves a good amount of air and is quiet.

A marca e o produto em si são muito bons, porém veio mal embalado e chegou avariado, com as paredes laterais tortas e pagando na hélice, precisei arrumar antes de usar.
