VIVOSUN 8-Inch Inline Booster Fan with Speed Regulator — 640 CFM Quiet Exhaust

Efficient airflow for your space

The VIVOSUN 8-inch inline booster fan delivers up to 640 CFM, designed to rapidly exchange stale air for fresh airflow in grow tents, basements, bathrooms, kitchens, and attics. A robust 2600 RPM motor powers the airflow, providing strong performance while keeping energy use reasonable. In everyday use, you may notice faster exhaust when vents open and a steadier background hum that stays unobtrusive in busy environments.

Powerful yet efficient airflow

This booster is engineered to maximize air exchange without overworking your HVAC or ducting. The combination of high output and an efficient blade design translates into steady air movement with a manageable energy draw, helping regulate temperatures, reduce humidity spikes, and help control odors in spaces that require reliable ventilation.

• Up to 640 CFM airflow for rapid air exchange
• Quiet operation at 45 dB(A) to minimize noise
• 2600 RPM motor for dependable performance
• Durable ABS housing and PBT blades resist deformation and wear
• Wide-voltage compatibility with a built-in stall protection

adjustability and setup

The unit includes a stepless speed controller, allowing smooth, precise tuning of airflow. This flexibility is useful as you adjust for different room sizes, grow stages, or changing occupancy. Easy to integrate with standard ducting and existing systems.

• Stepless control for precise airflow
• Smooth adjustments without abrupt changes in noise or draft
• Compatible with most ducting and installations
• Simple pairing with current ventilation setups

Durable design for everyday use

Constructed with a sturdy ABS housing and PBT blades, the fan is designed to withstand heat, humidity, and regular operation. The included wide-voltage power adapter supports diverse electrical environments, while stall protection helps maintain steady performance if airflow is momentarily challenged. These design choices contribute to reliable operation in spaces such as basements, attics, and workshops.

Practical use cases

Position the VIVOSUN inline booster near an intake or exhaust point in a grow tent to sustain fresh air and stable temperatures. In bathrooms or kitchens, use it to vent moisture and odors efficiently. For basements or attics, a compact, unobtrusive unit can improve air turnover without attracting attention.
