FAQs

What makes the VIVOSUN R8 ideal for large-scale operations?+

The R8's massive 720 CFM airflow at 2450 RPM is specifically designed for large spaces. This makes it perfect for commercial grow facilities, industrial applications, and large grow tents where significant air exchange is critical for maintaining a stable environment.

How does the R8 compare to smaller models?+

The R8 provides significantly more airflow than smaller fans. For comparison, the VIVOSUN R6 offers 390 CFM, while the R8 pushes 720 CFM. This makes the R8 suitable for applications where smaller fans would be insufficient to properly ventilate the space.

What size grow space is best for the R8 fan?+

The VIVOSUN R8's 720 CFM capacity is optimal for large grow spaces, such as 8'x8', 5'x10', or even larger commercial rooms. The variable speed controller allows you to fine-tune the airflow, making it adaptable for different stages of growth. For more information, check out our complete grow room setup guide.

How does the variable speed controller work?+

The included controller plugs directly into the fan and allows you to adjust the fan's speed by turning a simple dial. This gives you precise control over the RPM, letting you increase or decrease airflow from a gentle circulation up to the full 720 CFM extraction power based on your needs.

Is this fan suitable for continuous 24/7 operation?+

Yes, the VIVOSUN R8 is engineered for continuous, heavy-duty operation in environments with ambient temperatures up to 104°F (40°C). Its durable housing and robust motor are built for reliability in demanding applications like commercial grow facilities.

What do I need for installation?+

The R8 requires 8-inch ducting for proper airflow. The package includes a mounting bracket and hardware for secure installation. Its removable duct ends with locking tabs simplify the connection process, and the 5.9-foot power cord provides flexibility in placement.
