Yield Lab 6 Inch 440 CFM Duct Inline Fan Product Review

Built to be long-lasting, the Yield Lab 6 Inch 440 CFM Duct Inline Fan from Yield Lab boats powerful air circulation and durable design.

It provides 440 CFM and 2700 RPM, giving you ample airflow regardless of your grow room size.

It is constructed with solid metal, and the housing has a powder coat, making it pretty indestructible compared to other inline fans on the market.

It is a quiet fan even on the highest power setting, but the noise is known to increase after continued use. This is worth considering if you are looking to invest in this particular fan.

The power rating it possesses means that your grow room will be protected from any stale air or pungent odors.

The fan also contains a balanced motor and lubricated ball bearings, which make it longer lasting and smooth running.

A feature of this choice that could save you time and hassle in the long run is its built-in motor fan controller.

This means you don’t need to purchase any extra equipment, and you can simply plug in the fan and adjust the speed at your convenience.

As this is such a heavy-duty fan, one aspect to consider is that it is quite heavier than many 6” models, which could be a problem if you need to transport it or mount it in a hard-to-reach area.
