Why customers choose Cera Garden

Powerful, efficient ventilation for any space

The VIVOSUN 4-inch inline exhaust fan is engineered to move air reliably, delivering up to 130 CFM to help remove heat, moisture, and odors from a variety of spaces. Its compact form makes it suitable for grow tents, basements, kitchens, attics, and workshops, where efficient airflow can make a noticeable difference in comfort and air quality.

Beyond raw power, this unit emphasizes performance with an upgraded EC motor that combines strong airflow with lower energy use. The result is dependable ventilation that pairs well with longer run times, reducing the need for frequent maintenance while keeping operating costs in check.

Quiet operation is a key feature. At only about 26 dB(A), the fan blends into everyday environments, enabling you to run it during work, cooking, or leisure without distraction. This makes it a versatile choice for spaces that demand both airflow and calm surroundings.

Control, safety, and reliability

Fine-tuning airflow is effortless thanks to a stepless speed regulator that lets you dial in exactly the amount of ventilation you need. A wide voltage range power adapter supports compatibility with common electrical setups, while built-in safety features help mitigate hazards in busy or humid environments.

The design emphasizes durability and resilience. The sturdy ABS plastic housing resists deformation, and PBT blades provide enduring performance even in dusty or humid spaces. Stall protection adds a layer of reliability in fluctuating conditions, giving you confidence to run the system as needed.

Versatility across spaces

From grow tents and greenhouses to basements, bathrooms, kitchens, attics, and workshops, this vent booster fan is designed for diverse environments. It is also suitable for use with 3D printers and other hobby projects where clean, consistent air movement is important for comfort and safety.
