VIVOSUN 6” Inline Booster Duct Fan with Speed Regulator – 345 CFM

Meet the VIVOSUN 6” Inline Booster Duct Fan with Speed Regulator, a compact, robust solution designed to improve air exchange in a variety of spaces. This unit combines strong airflow with thoughtful design to support ventilation needs in grow tents, basements, bathrooms, kitchens, attics, and workshops.

Powerful airflow and efficient performance drive a comfortable environment without overpowering noise. The fan delivers up to 345 CFM, helping move stale air out and bring fresh air in, making it suitable for spaces that benefit from steady exhaust and supply ventilation. The integrated speed regulator lets you tune the balance between air change and energy use, so you can tailor operation to your current setup.

Key advantages include an upgraded EC motor for strong performance with lower energy consumption, a longer service life, and reduced maintenance costs. The durable ABS plastic housing and PBT blades resist deformation, staying efficient under varying temperatures and pressures. A wide voltage range enhances installation flexibility, while stall protection adds an extra layer of safety to prevent electrical issues.

Quiet operation and adjustable control

Despite its power, the booster fan operates quietly at about 32dB(A), allowing it to blend into daily life without constant distraction. The stepless speed regulator provides smooth, precise adjustments to match your ventilation needs, from gentle air replacement to robust exhaust.
