VIVOSUN 6-inch Inline Exhaust Fan & Speed Controller – 345 CFM, Low-Noise Duct Vent Fan

Meet a compact ventilation solution built to move air efficiently in a range of spaces. The VIVOSUN 6-inch inline exhaust fan delivers up to 345 CFM of airflow, helping you refresh grow tents, basements, bathrooms, kitchens, attics, and workshops. The upgraded EC motor combines power with economy, so you may experience less energy use over time and longer service life, while maintenance needs stay manageable.

Quiet operation matters for everyday spaces, and this model runs at approximately 32 dB(A) under typical conditions, keeping noise to a minimum while the fan works. The stepless speed regulator makes it easy to dial in the exact airflow you want, from gentle ventilation to stronger exhaust, without stepping through fixed speeds.

Durability is built in with a sturdy ABS plastic housing and PBT blades designed to resist deformation and wear. A wide voltage range power adapter adds flexibility for different installations, and safety features such as stall protection help prevent hazards, offering peace of mind as you run the fan in busy areas or near sensitive equipment like a 3D printer.

Real-world uses

Use cases span indoor grow setups, climate-controlled basements, odour-sensitive bathrooms, kitchen venting, attic cooling, and workshop dust management. The unit pairs well with ducting in tight spaces and can support adjustable ventilation for 3D printing tasks or seasonal ventilation needs.

• Grow tents and greenhouses seeking steady airflow
• Basements or attics needing bulk air exchange
• Bathrooms and kitchens requiring odor-control and moisture management
• Workshops and studios where quiet operation helps nearby tasks

To install, position the fan for efficient front-to-back airflow and connect to standard ducting. The built-in safety features and simple controls help you focus on your project rather than the technology behind it.
