5020A DC Blower Fan
Compact Size, High Static Pressure for Demanding Thermal Applications
In compact electronic systems, airflow alone is never enough. What truly determines cooling effectiveness is stable air pressure under system resistance. The 5020A DC Blower Fan (50.4 × 50.4 × 20.0 mm) is designed precisely for such scenarios, delivering reliable airflow and pressure in space-constrained, high-reliability applications.
Designed for Reliability and Stability
The 5020A DC Blower Fan features an engineering plastic frame and impeller, combined with a dual ball bearing structure. This configuration ensures stable operation, long service life, and consistent performance under continuous duty cycles. With a weight of just 35 g, it achieves an optimal balance between mechanical strength and compact design.
Performance Optimized for System Resistance
Unlike axial fans, blower fans are selected when airflow must overcome ducting, filters, or dense internal layouts. The 5020A series offers multiple speed and voltage options, providing flexibility for different system requirements:
-
Rated Voltages: 12V / 24V / 28V (5V and 48V optional)
-
Speed Range: 4,000 – 6,000 RPM
-
Airflow: up to 11.5 m³/h
-
Static Pressure: up to 120.6 Pa
-
Noise Level: as low as 30.5 dBA (model dependent)
This makes the 5020A particularly suitable for applications requiring controlled airflow with measurable pressure margins.
Signal Functions and Control Options
To support modern system integration, the 5020A DC Blower Fan supports multiple signal configurations:
-
PWM duty-cycle speed control
-
Tachometer (RPM) feedback
-
High-level fault alarm
-
Combined control and feedback options
These features allow precise speed regulation, real-time monitoring, and improved system safety.
Environmental Adaptability for Mission-Critical Use
The 5020A is developed in accordance with GJB military standards, ensuring reliable operation across harsh environments:
-
High and low temperature resistance
-
Humidity, salt spray, sand and dust protection
-
Shock, vibration, and acceleration endurance
-
EMC and power-supply compliance
Different environmental grades are available for ground, vehicle-mounted, and marine applications, enabling accurate selection without over-design.
Typical Applications
-
Power electronics and control cabinets
-
Communication and radar subsystems
-
Compact HVAC and thermal modules
-
Vehicle-mounted and industrial electronic equipment
A Reliable DC Blower Solution
The 5020A DC Blower Fan is engineered for applications where pressure stability, controllability, and long-term reliability matter more than size alone—making it a dependable choice for professional thermal management systems.
