4 Inch Mixed Flow Axial Inline Duct Fan Mixed Flow Fan

Core Features of the 4 Inch Mixed Flow Axial Inline Duct Fan Mixed Flow Fan
Crafted with precision to excel in inline duct applications, the 4 Inch Mixed Flow Axial Inline Duct Fan Mixed Flow Fan boasts features that set it apart from standard ventilation fans. At its core, a hybrid mixed flow design combines the high-pressure capabilities of centrifugal fans with the energy efficiency of axial fans, enabling it to move air through ductwork with minimal resistance while maintaining optimal airflow rates. The 4-inch size is compact yet powerful, fitting seamlessly into small to medium duct systems (4-inch diameter) without sacrificing performance.

Powered by a high-efficiency motor (available in AC, DC, and EC variants), the fan operates with low energy consumption and quiet performance. AC motor variants exceed national Grade 1 energy efficiency standards, while EC motor models offer an extended lifespan of over 20,000 hours and mute operation at ≤43 dB—ideal for noise-sensitive environments. Each unit undergoes rigorous aging tests and quality inspections using over 100 professional tools, ensuring compliance with ISO 9001, CE, UL, and RoHS certifications. Additional features include a durable metal housing for corrosion resistance, customizable speed settings (1-3 speeds), and easy-install mounting brackets, making the 4 Inch Mixed Flow Axial Inline Duct Fan Mixed Flow Fan adaptable to a wide range of project requirements.

Key Advantages of Our Mixed Flow Inline Duct Fan
The 4 Inch Mixed Flow Axial Inline Duct Fan Mixed Flow Fan offers unmatched advantages that address the pain points of ventilation system designers, contractors, and facility managers. Balanced airflow and pressure is a standout benefit: the mixed flow design generates sufficient static pressure to overcome duct resistance (bends, filters, long runs) while delivering consistent airflow (up to 500 CFM, depending on configuration), eliminating stagnant air and pressure imbalances.

Energy efficiency translates to tangible cost savings, with the fan’s advanced motor technology reducing electricity expenses by up to 25% compared to conventional inline fans. Durability is another major strength—its robust metal construction and precision-engineered components resist wear, vibration, and temperature fluctuations (-10°C to 60°C), minimizing downtime and replacement costs. Backed by Zhongshan Pengfei’s track record of serving 500+ enterprises (including 20 listed companies) with a 92% repurchase rate, the fan is proven to withstand continuous use in demanding environments. Fast lead times enhance convenience: standard configurations ship in-stock, while customized 4 Inch Mixed Flow Axial Inline Duct Fan Mixed Flow Fan samples are ready in 48 hours and mass production delivered in 12 days, supporting timely project completion.
