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

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.

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.

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.

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

The 6" 275 CFM Inline Booster Duct Fan with Speed Controller is a durable and adaptable airflow enhancement tool for a range of home and commercial ventilation systems. Made from premium materials that guarantee lifespan and durability, the fan has a stylish and robust design. Its compact design makes installation simple even in confined places, and its 6-inch duct size makes it compatible with the majority of common duct systems. This duct fan is capable of producing an astonishing 275 CFM (cubic feet per minute), which efficiently boosts ventilation in a variety of scenarios. It worked incredibly well during testing, greatly enhancing the airflow in a small grow tent and a medium-sized room. The fan makes some noise when it works, but it is not totally silent. It is suitable for usage in situations where minimizing noise is vital because it is hardly noticeable at lower speeds. The noise level rises with increasing speeds but stays within a bearable range, similar to other duct fans in the same class. Installation is simple and comes with detailed instructions. An improved one.
