High Airflow & High Static Pressure Performance
The 5048A series offers multiple speed configurations to meet different cooling requirements, delivering a strong balance between airflow and static pressure:
-
Airflow: up to 95.6 m³/h
-
Static pressure: up to 850 Pa
-
Speed range: 10,000–22,000 RPM
-
Rated voltage: 28 VDC (5V / 12V / 24V / 48V optional)
This makes the fan particularly suitable for high-density electronic enclosures, power electronics, radar systems, and sealed equipment with high airflow resistance.
Flexible Signal & Control Options
To support system-level monitoring and control, the 5048A fan supports multiple signal configurations:
-
PWM duty cycle speed control
