Product Overview
The AOSUNFAN Inline Centrifugal Fan (Model IC-315) is engineered for high-pressure HVAC systems and industrial ventilation, combining centrifugal force efficiency with axial fan compactness. Available in 200–315 mm diameters, its galvanized steel backward-curved blades generate 1,200–6,500 m³/h airflow at 650–2,200 Pa static pressure (AMCA 210 certified). Featuring a 3-phase AC motor (IP55-rated) with 15% higher efficiency than standard models (ISO 5801 compliant), it operates at ≤68 dB(A) while supporting 24/7 duty cycles in -20°C to 80°C environments. Compatible with ducted systems and IoT-enabled VFD controllers.
Product Features
High Static Pressure Design
Optimized impeller geometry achieves 35% higher pressure vs. axial fans (tested per ASHRAE 51).
Corrosion Resistance
Epoxy-coated housing + stainless steel fasteners withstand acidic fumes (pH 3–11) and 90% RH humidity.
Low Noise Operation
Rubber-isolated motor mounts reduce vibration transfer by 50% (ISO 14694-1 Class B).
Custom Configurations
OEM modifications include explosion-proof variants (ATEX Zone 22) and BMS-ready control panels.

FAQ
Q1: How does this Inline Centrifugal Fan differ from axial fans?
Unlike axial fans limited to ≤800 Pa pressure, our Inline Centrifugal Fan delivers 2,200 Pa static pressure with 50% lower noise—ideal for long-duct HVAC systems.
Q2: Minimum duct straight-run requirement?
Install ≥1.5x duct diameter upstream and ≥3x diameter downstream for optimal airflow (per AMCA installation guidelines).
Q3: Bearing lubrication intervals?
Sealed-for-life ceramic bearings require no relubrication (MTBF 60,000 hours @ 40°C ambient).
Q4: Smart airflow adjustment?
Integrates with Building Automation Systems via 0-10V/PWM signals for dynamic pressure control (±2% accuracy).
