Dreyoo 6" Inline Duct Fan 2-Pack — 460 CFM per Fan, Quiet 6" Ventilation with Rust-Resistant Housing

The Dreyoo 6-inch inline duct fan 2-pack delivers powerful 460 CFM airflow with quiet operation to improve ventilation in grow tents, basements, bathrooms, and other indoor spaces.

These two 6" inline duct fans are designed to move large volumes of air while keeping noise low, making them useful where both performance and discretion matter. Each unit runs on 110–120V with a 40W motor and 3000 RPM speed, and the set includes duct clamps for easy installation. The fans are coated to resist rust for longer indoor life, but they are not engineered for continuous outdoor exposure.

How will this 2-pack improve air exchange in my grow tent or mini greenhouse?

The paired fans provide more consistent ventilation than a single unit: you can run them together for faster air turnover or separate them to serve two smaller spaces. High static pressure and 460 CFM capacity help maintain stable temperatures and reduce humidity spikes, which supports healthier plant environments.

• 460 CFM per fan with 3000 RPM for strong, steady airflow
• Use in parallel to double air volume without raising pressure
• Includes duct clamps for secure connections to 6" ducting
• Compact 6" size fits common grow tent duct ports

Are these fans quiet enough for living areas or bedrooms?

Dreyoo built these fans with noise-reduction measures so they run more quietly than many high-CFM alternatives. They still produce sound when moving large volumes of air, but the reduced vibration and motor dampening make them suitable for spaces where noise is a concern.

• Noise-reducing design decreases motor and vibration noise
• Good for bathrooms, living rooms, or bedroom-adjacent installations
• Long 6.5 ft power cord allows flexible placement away from occupants

How do I install and configure the fans for best results?

Installation is straightforward: mount inline in your duct run and secure with the included clamps. For larger setups, consider parallel wiring to maximize airflow or series arrangement for longer ducts—each configuration changes airflow behavior, so choose based on distance and resistance.

• Mount inline with 6" ducting using provided clamps for a tight seal
• Parallel connection increases volume without boosting static pressure
• Series connection helps overcome long duct runs but reduces overall flow
• Allow periodic shutdowns during extended continuous use to cool motors

What are the power and durability details I should know?

Each fan runs on 110–120V, consumes 40W, and spins at 3000 RPM, offering strong performance without excessive power draw. The housing has a rust-resistant coating for indoor longevity; however, these fans are not rated for outdoor weather exposure or direct outdoor mounting.

• Power: 40W per fan; Voltage: 110–120V
• Fan speed: 3000 r/min with 70 Pa wind pressure
• Rust-proof coating for indoor corrosion resistance
• Not intended for permanent outdoor installations

Who is this for: The Dreyoo 6-inch inline duct fan 2-pack is ideal for hobby growers, home HVAC improvers, and homeowners who need reliable, low-noise ventilation for grow tents, closets, bathrooms, basements, garages, or workshops. Choose this set if you want compact fans that deliver strong 460 CFM airflow, flexible installation options, and quieter operation than many comparable high-flow duct fans.
