9330A DC Blower Fan
High-Pressure DC Blower Fan for Industrial & Mission-Critical Cooling
The 9330A DC Blower Fan (93 × 90 × 30 mm) is a high-performance centrifugal cooling solution designed for applications requiring stable airflow, high static pressure, and long-term reliability. It is widely used in industrial electronics, power systems, communication equipment, and demanding thermal environments.
Engineered for Reliable Performance
The 9330A series features a robust dual ball bearing structure, ensuring extended service life and stable operation under continuous duty conditions. Both the frame and impeller are made of high-strength engineering plastic, providing an excellent balance between mechanical durability and lightweight design.
With multiple speed options ranging from 2000 to 4000 RPM, the fan delivers airflow up to 39.5 m³/h and static pressure up to 321.6 Pa, making it well-suited for compact systems with high airflow resistance.
Flexible Voltage & Control Options
The 9330A DC blower fan supports 12V, 24V, and 28V configurations (with additional voltage options available), allowing easy integration into different power architectures. Optional control and monitoring functions include:
-
PWM duty cycle speed control
-
Tachometer (RPM) feedback
-
High-level fault alarm
-
Combined control and monitoring signals
These features enable precise thermal management and system-level diagnostics.
Environmental Adaptability
Designed to meet GJB military and industrial environmental standards, the 9330A series demonstrates strong resistance to:
-
High and low temperatures
-
Humidity, rain, salt spray, and dust
-
Vibration, shock, and acceleration
This makes it suitable for ground-based, vehicle-mounted, and industrial-grade environments where reliability is critical.
