EC Centrifugal Fans for AHU Systems in European Commercial Buildings
Why EC Centrifugal Fans Are Critical for European AHU Systems
In Europe's commercial building market, AHU (Air Handling Unit) systems face mounting pressure from strict efficiency and design standards, notably:
-
Ecodesign Directive (EU 1253/2014) for NRVU/RVU energy performance
-
EN 13053 for AHU performance grading (pressure, temperature, efficiency)
-
EN 1886 for housing strength, leakage, thermal bridge, and insulation
-
Demand for Eurovent-certified system configurations
Against this backdrop, EC centrifugal fan walls—like the AFL EC fan solution—are emerging as the go-to upgrade path for HVAC engineers, facility managers, and mechanical contractors.
Key Compliance Questions from European Buyers
| Question | AFL EC Fan Answer |
|---|---|
| Can your fan system meet EU 1253/2014 and EN 13053 classifications? | Yes – full conformity with both fan and AHU-level metrics |
| Do your fans support variable speed & BMS integration? | Native support for 0–10V, PWM, RS485 + Modbus/BACnet |
| How do you address noise, leakage, and lifecycle cost concerns? | Balanced blades, FOC sinusoidal control, sealed housings, maintenance-free design |
| Do you offer performance documentation for tender submission? | Yes – EN 1886 leak tests, EN 13053 curves, Eurovent-style data sheets |
