VIVOSUN 8" Metal Inline Fan 420 CFM — 8-inch Exhaust Fan, Quiet 40 W Corrosion-Resistant Housing

The VIVOSUN 8" Metal Inline Fan delivers up to 420 CFM of airflow in a compact, corrosion-resistant metal housing for reliable ventilation in tight spaces.

Designed for homeowners, hobby growers, and light commercial HVAC tasks, this 8-inch inline exhaust fan balances high air movement with a compact footprint and quiet operation. It pairs a rugged metal construction with a permanently lubricated motor for maintenance-free performance and can be used to move fresh air into or stale air out of bathrooms, kitchens, workshops, basements, attics, and grow rooms.

How loud is the fan during typical use?

Noise was considered in the design through a balanced centrifugal impeller and durable bearings, so the fan runs quietly for its class. Typical sound levels remain low enough for most indoor tasks without creating distraction or interruption.

• Measured below about 40 dB in normal operation.
• Balanced impeller reduces vibration and tonal noise.
• Permanently lubricated bearing eliminates squeaks and reduces maintenance.

What performance can I expect from an 8-inch, 420 CFM fan?

The fan moves a substantial volume of air for its diameter, making it suitable for short duct runs and localized exhaust or intake points. Its 2970 RPM motor is tuned to provide steady, consistent airflow for ventilation or odor control.

• Rated airflow: up to 420 cubic feet per minute (CFM).
• Motor speed: roughly 2970 RPM for continuous duty.
• Power draw: approximately 40 watts at 110–120 V.

Is this inline fan easy to install and maintain?

The compact, lightweight metal body is intended for installations where space is limited and fits standard 8-inch ducting. Maintenance is straightforward: periodic cleaning keeps the impeller and motor running efficiently and prolongs service life.

• Compact 8-inch diameter fits common ductwork and tight spaces.
• Corrosion-resistant metal housing for long-term durability.
• Recommended cleaning after the first week with a filter connected, then on a regular schedule based on environment.

Where is it safe to use this fan and what are its limits?

The fan is suitable for a wide range of indoor ventilation tasks but should be protected against direct exposure to combustible dust and liquids. Follow operating temperature guidelines and shut off the unit if the impeller becomes obstructed.

• Voltage: 110–120 V; power: 40 W.
• Maximum motor temperature: 130°C (266°F); maximum ambient: 60°C (140°F).
• Not designed for environments with heavy particulate or flammable vapors without proper filtration and safety controls.
• Turn off immediately if blades become jammed by foreign objects.

Who is this for? The VIVOSUN 8" Metal Inline Fan is aimed at homeowners and small-scale growers who need reliable, compact ventilation that packs strong airflow without a bulky footprint. It's a good fit for bathroom and kitchen exhaust upgrades, ventilation in workshops or basements, and use as intake or exhaust in grow tents or small grow rooms. If you need a durable, maintenance-light inline fan that balances performance and quiet operation in confined spaces, this model is built for that role.
