Inline duct fan with variable speed control

The VEVOR VV-GDFJ-AC4 is a 4-inch inline duct blower rated at 200 CFM. It runs on 120 V AC power and includes a variable speed controller. The unit uses a copper motor drawing 31 W at 2550 RPM. It is built for exhaust, cooling and ventilation tasks.

Grow tents, hydroponics and equipment cooling

This blower suits grow tents, hydroponic rooms, kitchens, basements and electronic equipment rooms where heat, humidity or smoke must be removed. The package supplies rubber mats, a hang-up sling and screws for suspended or surface mounting. Buyers needing higher static pressure or airflow beyond 200 CFM should look at larger units.

200 CFM airflow at 165 Pa static pressure

The fan delivers 200 CFM against 165 Pa of static pressure, which determines whether it can overcome duct resistance in a given layout. Noise is listed at 50 dB, with a quieter 29 dB figure noted. The 12 x 9.3 x 7.5 in housing weighs 4.4 lbs.

Questions about this item

What duct diameter must I already have for this 4-inch inline blower to connect?

The unit is built for 4-inch ducting, so your existing ductwork must match that diameter for a proper fit.

How does the 29 dB noise level compare with the older 50 dB fans I might still run in the same space?

At 29 dB this blower runs noticeably quieter than a 50 dB fan, so it will not add disruptive noise alongside older equipment.

After wiring the 120 V AC supply and setting the speed controller, what indicates the blower is delivering its rated 200 CFM?

You should feel strong, steady airflow at the duct outlet and hear only the low 29 dB hum, confirming the 2550 RPM motor is operating as specified.
