Circular Metal Inline Duct Fan – Ideal for Long-Duct Ventilation & HVAC Systems

The Circular Metal Inline Duct Fan series is engineered for high-resistance ventilation systems, combining rugged construction with efficient performance to solve airflow drop-off issues commonly faced by traditional axial fans in long-distance duct applications.

Core Advantages:

High Static Pressure · Durable Metal · Low Noise Operation

Unlike common plastic duct fans on the market, this series features a galvanized steel housing paired with a backward-curved centrifugal impeller, delivering significantly higher static pressure to easily overcome system resistance caused by long duct runs, multiple bends, and air filters. The direct-drive external rotor motor ensures stable airflow while keeping operating noise at a low level, making it suitable for noise-sensitive residential and commercial spaces.

Typical Applications:

Commercial Building Ventilation: Fresh air supply and exhaust systems in office buildings, hotels, and shopping malls.

Kitchen & Bathroom Exhaust: Boosting exhaust in long-range ductwork or shared flues in high-rise residential buildings.

Industrial & Garage Ventilation: Welding fume extraction in workshops, basement and parking garage ventilation.

Product Highlights:

Housing Material: Anti-corrosion galvanized steel

Impeller Type: Backward-curved centrifugal impeller

Motor Type: External rotor motor (speed control optional)

Mounting: Equipped with L-shaped brackets, supports horizontal and vertical installation

Protection Rating: IP44, suitable for both indoor and outdoor environments

We specialize in the R&D and manufacturing of high-quality HVAC ventilation equipment, committed to providing reliable and energy-efficient ventilation solutions for the global market.The metal body ensures a service life far exceeding that of plastic fans in humid and dusty environments.
