8-Inch 750 CFM Inline Duct Fan

The VEVOR VV-GDFJ-AC8 is an 8-inch inline duct fan rated at 750 CFM for high-volume air movement. It suits grow tents, hydroponic setups and cooling booster applications where strong exhaust or intake flow is required. The unit runs on AC 120V at 50/60 Hz and draws 126 W at full speed.

Copper Motor With Variable Speed Controller

A copper motor spins at 2500 RPM to deliver 320 Pa of air pressure while operating at 50 dB, dropping to about 38 dB at lower settings. The included variable speed controller lets you match airflow to daily conditions without rewiring. Four rubber mats, a hang-up sling and self-tapping screws provide flexible mounting on walls, ceilings or tent frames.

Replaces Smaller Fixed-Speed Units

This fan replaces lower-capacity or single-speed models when a grow space demands 750 CFM and adjustable output. The jump is worth it when environmental control requires both high static pressure and quiet low-speed operation. Buyers needing duct diameters other than 8 inches or a different voltage supply should look elsewhere.

Questions about this item

What is the maximum airflow the VV-GDFJ-AC8 delivers at its 120 V AC rating?

The fan is rated for 750 CFM at 120 V AC, 50/60 Hz, driven by a 126 W copper motor spinning at 2500 RPM.

What are the exact dimensions and weight I need to clear for mounting?

The unit measures 12 x 9.3 x 11 in (303 x 235 x 280 mm) and weighs 6.8 lbs (3.08 kg); four rubber mats and a hang-up sling are included for vibration isolation.

How do I wire the variable-speed controller so the fan runs at the advertised 38 dB low speed?

Connect the controller between the 120 V supply and the fan leads; the lowest dial position reduces motor voltage to achieve approximately 38 dB, while the highest gives full 750 CFM at 50 dB.
