Hon&Guan 4 Inch Inline Booster Duct Fan with Speed Controller - 130 CFM Airflow with 6W Ultra-Low Power and Low Noise

Good product

The worst purchase of 2024! Super cheap “full plastic build “ not recommended.

Muy fácil de usar, hace ruido, pero para mi uso que es un extractor de humo de soldadura, lo conecte con un tubo de extractor y coloque el extractor en una especie de tela colgante para evitar que la vibración hiciera ruido, añadí en la punta un filtro de carbón, y funciona excelente

Super produit, aspire vraiment. Je m'en sers comme aspiration de fumée de découpe laser, c'est top. Par contre il est très bruyant.

Good for its job and price

exhaust powe Good

This does exactly what I need, well! Wanted a forced air duct from my sun room (lots of windows/poor insulation) to the basement, pulling cold winter air or hot summer air down to be conditioned by the furnace/AC. Also to create airflow from the rest of the house in that direction to keep the rest of the home from being affected by that air, offering a preferred path of return air to the furnace/AC. This worked perfectly; initially it was a little noisy (if being VERY picky) but I ran ~12' of flexy hose (the type with the wire coil and flexible plastic) before the fan, and put plenty of twists and bends in it. Works practically silently now even at higher speeds. My home is much more comfortable without having the noisy forced air and AC kick on so much. Been running for months now without any issues. Love the speed control unit too, easy to install somewhere accessible and extend the cable if needed.
