VIVOSUN 8-inch Inline Fan 720 CFM — Stepless Speed Controller, Low-Noise Compact Ventilation

The VIVOSUN R8 8" Inline Fan delivers up to 720 CFM of controlled air movement in a compact, low-noise package ideal for grow tents, bathrooms, basements, kitchens and attics.

Engineered to combine axial speed with centrifugal pressure, the R8 gives high airflow without the bulk of larger units. Its reinforced plastic housing and smooth-blade design keep weight low while minimizing vibration and acoustic output. With a stepless speed controller on the power cord and removable duct ends, the unit is simple to adjust and install in tight ductwork or limited spaces.

How much airflow and noise performance can I expect?

The R8 produces up to 720 CFM at 2450 RPM for strong, continuous ventilation while staying quiet enough for indoor use. VIVOSUN designed the blades and motor mounting to reduce turbulence and mechanical noise.

• Maximum airflow: 720 CFM for rapid air exchange
• Fan speed: 2450 RPM for consistent output
• Noise level: typically under 38 dB in normal operation
• Balanced blade design to reduce vibration and whine

Can I control the speed to match different ventilation needs?

Yes — a stepless speed controller on the attached power cord lets you dial the fan from low to high without discrete steps. That makes it easy to tune airflow for plant canopies, moisture control, or workshop cooling.

• Stepless controller for fine-grain airflow adjustment
• Quick changes without rewiring or external controllers
• Suitable for gradual ramping or fixed setpoints
• Helps balance intake and exhaust to manage pressure

How easy is installation and how durable is the unit?

The R8 is built with a reinforced plastic housing and removable duct ends with locking tabs for straightforward mounting. It includes a bracket that marks airflow direction so you can install it correctly the first time.

• Compact, lightweight body fits small spaces and tight ducts
• Installation bracket included with airflow direction indicated
• Removable duct ends with locking tabs for secure connections
• Durable plastic casing resists corrosion and keeps weight low

What environments and uses suit this inline fan best?

The VIVOSUN R8 is versatile for household, light industrial, and horticultural ventilation. It moves large volumes of air quietly, making it useful for moisture control, odor management, and heat dissipation in confined areas.

• Indoor grow tents and grow rooms for canopy circulation
• Bathrooms and basements to remove moisture and reduce mold risk
• Kitchens and attics for supplemental ventilation and heat removal
• Small workshops and 3D printing spaces for dust and heat control

Who this is for: The VIVOSUN R8 8" Inline Fan fits homeowners and hobby growers who need reliable, adjustable airflow in compact spaces, as well as small workshop or light industrial users who want high CFM without excessive noise. Choose this model when you need a balance of power, quiet operation, and easy installation for ducted ventilation systems.
