6-Inch High-Efficiency Inline Duct Booster Fan (420 CFM)

Powerful 420 CFM High-Velocity Airflow: Engineered with aerodynamically optimized fan blades to deliver a robust, ultra-strong wind output of 420 Cubic Feet per Minute (CFM). It rapidly clears out stale air, heavy smoke, humidity, and heat.

Heavy-Duty All-Copper Wire Motor: Driven by a premium, 100% pure copper wire motor that offers superior thermal efficiency, reduced power consumption, and enhanced heat dissipation, resulting in a significantly longer lifespan compared to standard aluminum motors.

Universal 6-Inch Pipeline Fitment: Features dual-ended flanged connections that hook up seamlessly to standard 6-inch flexible aluminum ducting or rigid pipes, functioning perfectly as both an intake fan and a primary exhaust booster.

Whisper-Quiet, Smooth Operation: Utilizes precision-balanced centrifugal impellers and dual ball bearings to dramatically reduce operational friction, vibration, and hum, maintaining high-volume air circulation without disrupting your home environment.

Versatile Home & Professional Ventilation: The ideal air-exchange solution for residential and commercial spaces alike—expertly managing odor and moisture control in master bathrooms, cooking kitchens, damp basements, indoor hydroponic grow tents, and greenhouses.

Built to Last in High-Moisture Environments: Constructed using a rugged, impact-resistant external housing that shields internal motor components from moisture, steam, and dirt accumulation, making it highly reliable for continuous 24/7 heavy-duty operation.

Compact, Space-Saving Layout: Designed with a streamlined inline profile that can be mounted easily in tight attic spaces, wall joists, or overhead ceiling grids without taking up valuable room floor space.
