20070A DC Axial Flow Fan
High-Power Cooling Solution for Demanding Industrial & Defense Applications
As electronic systems grow larger and more powerful, thermal management becomes a critical design challenge. The 20070A DC Axial Flow Fan is engineered for applications that require high airflow, strong static pressure, and long-term reliability in harsh operating environments.
With a Φ200 × 70 mm form factor and robust structural design, this model is ideal for high-density equipment where heat dissipation cannot be compromised.
Robust Structural Design for Heavy-Duty Use
The 20070A DC axial fan adopts a hybrid structural design, combining mechanical strength with optimized airflow performance:
-
Frame: Aluminum alloy housing for superior rigidity and heat resistance
-
Impeller: High-strength engineering plastic, optimized for airflow efficiency
-
Bearing Structure: Dual ball bearings for extended service life and stable operation
-
Weight: 1800 g, ensuring mechanical stability under vibration and shock
This structure enables the fan to operate reliably in industrial, vehicle-mounted, and defense-related systems.
High Airflow & Static Pressure Performance
Designed for high-load thermal environments, the 20070A delivers exceptional cooling capacity:
| Parameter | Value |
|---|---|
| Rated Voltage | 48 V (options: 5V / 12V / 24V / 28V / 48V) |
| Operating Voltage Range | 32.0 – 56.0 V |
| Power Consumption | 100 W |
| Speed | 4600 RPM |
| Airflow | 924.4 m³/h |
| Static Pressure | 720.3 Pa |
| Noise Level | 69 dBA |
Rather than focusing on airflow alone, the fan is optimized for real operating points, ensuring effective cooling even in systems with high airflow resistance.
Flexible Control & Monitoring Options
To meet different system control requirements, the 20070A supports multiple signal configurations:
-
PWM duty-cycle speed control
-
Tachometer (RPM) feedback
-
High-level fault alarm
-
Combined control and monitoring functions
These options allow seamless integration into intelligent thermal management systems.
Proven Environmental Adaptability
The 20070A DC axial fan is designed in accordance with GJB military environmental standards, making it suitable for harsh and mission-critical applications:
-
High & low temperature resistance
-
Salt spray and humidity endurance
-
Sand, dust, shock, vibration, and acceleration tolerance
