Inline duct fan for targeted airflow

The VEVOR VV-GDFJ-AC6 is a 6-inch inline duct fan rated at 400 CFM and 300 Pa of air pressure. It runs on a 120V AC copper motor drawing 60 W at 2600 RPM. The unit suits grow tents, hydroponic setups and cooling boost applications where ducted exhaust or intake is required.

Speed control and noise trade-offs

A variable speed controller lets you reduce airflow from the maximum 400 CFM to match the duct length and filter resistance you actually have. At full speed the manufacturer states 50 dB, dropping to about 34 dB when slowed. Lower speeds cut noise but also reduce the static pressure available to push air through long or restricted runs.

Mounting hardware and physical footprint

The fan body measures 12 x 10 x 8.4 in and weighs 6.3 lbs. Included rubber mats and a hang-up sling allow ceiling or wall suspension to isolate vibration. Four self-tapping screws are provided for direct mounting, though the supplied hardware suits wood or metal studs rather than concrete without additional anchors.

Questions about this item

Should I choose the 6-inch 400 CFM model or a smaller diameter for my grow tent?

The 6-inch 400 CFM unit matches standard 6-inch ducting and delivers 400 CFM at 300 Pa pressure, making it suitable for medium tents where that airflow and static pressure are required.

What does the 400 CFM rating mean once the fan is installed in a duct run?

In a real duct run the 400 CFM is the free-air maximum; actual airflow drops with each bend, filter or length of duct, so expect lower delivered volume depending on your layout.

The fan runs on AC 120 V 50/60 Hz — does that limit speed control options?

The included variable-speed controller adjusts the AC motor speed directly, letting you reduce airflow and noise below the 2600 RPM / 50 dB maximum without needing a special PWM or DC interface.
