About This

• 【Powerful & Quiet Airflow】 The 4 inch inline duct fan with speed control impresses with its dynamically balanced design, which eliminates vibrations and noise and reduces the noise level by up to 20%. The 8 reinforced blades made of high-purity, impact-resistant ABS plastic minimize airflow losses and increase pressure efficiency – airflow increases by up to 40%. Even with a duct length of over 10 meters, performance and air volume remain consistently strong
• 【Stable & Efficient Motor Performance】 The safe, energy-efficient motor with dual ball bearings and a pure copper core features built-in overheat protection, extends service life, and saves up to 40% energy. The adjustable inline duct fan ensures consistently quiet operation with steady airflow – more stable and efficient than conventional motors. Adjust the airflow steplessly from 0% to 100% – no humming at low speed
• 【Integrated design & globally certified】 This inline exhaust fan comes with a US-standard plug and a 3-meter cable for plug-and-play use—no disassembly required, eliminating the risk of electric leakage. The package includes screws and a speed controller for precise stepless speed adjustment. Certified to CE, VDE, RoHS, and FCC, meeting all safety standards in both the EU and US markets. Reliable replacement service is provided during the warranty period
• 【Robust, Durable & Weatherproof】 The housing of the 4 inch inline duct fan is made of high-quality ABS material with high strength, corrosion resistance and impact resistance – rust-proof and more durable than metal fans. Rigorous drop tests guarantee a stable structure. With an IPX4 rating, the fan is water-resistant and moisture-resistant, ideal for damp rooms and long-term use
• 【Versatile Application for Various Environments】 The adjustable inline duct fan (280 CFM) quickly removes humid air from washrooms, stale air from basements and attics. Exhaust air from 3D printers or laser cutters is also efficiently extracted. In combination with grow tents or activated carbon filters, it ensures fresh, clean air even in small spaces – suitable for private households, workshops, and commercial use
