Description
xMeet the VIVOSUN R4 4-Inch Inline Duct Fan, a purpose-built solution for moving air smoothly in compact spaces. Built for grow tents, hobby rooms, bathrooms, and other indoor environments, this fan aims to balance performance with ease of use. The R4 blends the strengths of axial and centrifugal designs to deliver reliable airflow where it matters most, all while keeping energy use in check.
Performance and efficiency take center stage. The unit can deliver up to 190 CFM at 2300 RPM, making it capable of refreshing air across typical grow tent setups and small workshops. By promoting steady air movement, it helps dissipate heat pockets, manage humidity, and support a stable ambient environment for equipment and plants alike.
Fine-tuned airflow is within reach thanks to the stepless speed controller on the power cord. This lets you dial in the exact air volume needed to balance temperature, humidity, and noise. The ability to reduce speed when fewer plants are in the tent or when external conditions change means you can tailor performance to your exact needs, rather than relying on a single setting.
Installation is straightforward. The R4 is compact and lightweight, so it fits into tight spaces. It ships with a mounting bracket that clearly indicates airflow direction, and the duct ends are removable with locking tabs for quick, secure connections. This setup supports flexible orientation to suit your duct routing and tent layout.
What you can achieve with the R4
- Energy-efficient ventilation delivering up to 190 CFM at 2300 RPM for robust air movement.
- Low noise operation with blades designed for smooth, steady airflow.
- Adjustable airflow via a stepless controller for customized ventilation.
- Compact footprint ideal for indoor grow tents, bathrooms, basements, and workspaces.
- User-friendly installation with bracket, direction guide, and secure duct ends.
In real-world setups, you might pair the R4 with carbon filters, ducting, and other ventilation components to support a balanced indoor climate. Its compact size and adjustable speed make it a practical choice for small grow tents, moisture-prone bathrooms, or a home workshop that generates heat or dust. The unit’s robust construction translates to dependable operation in environments that demand continuous airflow without taking over the space.
