The Backward Inclined Inline Fan provides an efficient solution for space-saving ventilation in industrial buildings. These fans combine the power of a centrifugal wheel with the straight-through airflow of an axial fan. This unique design allows for installation directly into existing ductwork. We offer sizes ranging from 8” to 36” to accommodate various air volume requirements.

Acoustic Excellence of the Backward Inclined Inline Fan

This fan series runs much quieter than standard tube axial fans. The backward inclined wheel minimizes turbulence and reduces noise levels across all operating speeds. We also include a precision-spun inlet cone. This component guides air smoothly into the wheel to maximize pressure and efficiency. You can [view our internal catalog of quiet fans] to compare different models for your facility.

The Backward Inclined Inline Fan ensures air moves smoothly through your ducted or non-ducted applications. You can choose between direct-drive and belt-drive configurations based on your specific system needs. A high-strength carbon steel shaft supports the internal components for stable, vibration-free performance. For more technical data, you can [read our industrial fan performance guide].

Robust Construction of the Inline Centrifugal System

We use high-grade mild steel for the standard construction of these units. Every fan receives a corrosion-resistant primer and a professional enamel paint finish. This double layer protects the metal from moisture and harsh industrial fumes. Removable side panels make routine maintenance very simple. Technicians can access the motor and wheel without removing the entire unit from the ductwork.

Our Backward Inclined Inline Fan uses a TEFC motor for maximum durability. These motors feature IP54 protection and Class F insulation. They meet IE2 efficiency standards to help you lower energy costs. The electrical system runs on a 380/400 V, 50 Hz, 3-phase supply. This makes the fan suitable for heavy-duty commercial and industrial use.
