Technical Highlights:
-
Performance Scaling:
-
38.7x airflow increase from No.1.0 (150 m³/min) to No.4.0 (5800 m³/min).
-
Linear pressure rise (50 Pa → 360 Pa) with model size.
-
-
Efficiency Metrics:
-
Noise/Flow Ratio: Smaller models (No.1.0-1.8) achieve <50 dB(A) at 650+ m³/min.
-
Power Density: No.4.0 delivers 7.73 m³/min per 100W (industry-leading).
-
-
Dimensional Precision:
-
D (Blade diameter) / D1 (Housing) tolerances ≤±2mm.
-
L (Length) optimized for duct compatibility (135-190mm).
-
Comparative Analysis:
| Model | Key Advantage | Best For |
|---|---|---|
| No.1.5-1.8 | Ultra-quiet (<50 dB(A)) | Laboratories, offices |
| No.2.5-3.0 | Balanced pressure/flow (1850-2650 m³/min) | Commercial kitchens, server rooms |
| No.3.5-4.0 | High-pressure industrial use (235-360 Pa) | Factories, warehouse ventilation |
Installation Notes:
-
Mounting: Flange or bracket installation (pre-drilled holes on housing).
-
Maintenance: Accessible motor compartment for servicing.
