BITMAIN Antminer T9 S1 S3 S5 S7 S9 A3 D3 L3 V9 120mm High Temp Fan Duct 4 INCH USA Made (2 PCS)

Used to exhaust some hot air from crawl space. Does the job

Exactly what I needed to affix a round filter to a 120mm fan

Pues para el propósito que se quería si se logro todo muy bien

This 120mm duct adapter is of good quality. It’s a hard composite that should stand up to any application, even industrial.

Es un producto de muy buena calidad, lo volveré a comprar para otros antminer, se ensambla a la perfección y permite un flujo de aire adecuado para el enfriamiento de la máquina. Estoy feliz con mi compra.

Worked for me with AC Infinity Flexible 4-Inch Aluminum Ducting. Used to route exhaust fan away from computer to keep it cooler. Wish the inside was black too.... Worked fine. Just seems a little over priced.But would buy again......

If you have Antminers you are dealing with the heat they produce. I bought these to combine them with an exhaust tube to move the heat outside of the building. These fit snuggly to the units and were easy to use (everything lined up). I would buy these again in a heart and probably be purchasing more soon.
