Application Scenarios and Performance Characteristics
This axial flow fan excels in applications requiring consistent, high-volume airflow with moderate static pressure. The 120mm size makes it particularly suitable for rack mount enclosures, server cabinets, and industrial control systems where space is at a premium. The 24V operation provides compatibility with industrial power systems commonly found in manufacturing facilities, while the 0.8A current draw ensures it can be powered from standard industrial power supplies without requiring specialized circuitry.
The fan's axial design creates a straight-through airflow path, making it ideal for applications where air needs to be moved across heat sinks or through ventilation ducts. Compared to centrifugal fans, axial fans like the BP1203824H-03 typically offer higher airflow volumes at lower static pressures, making them perfect for applications with minimal airflow resistance.
Buying Considerations: Selection Guide for Industrial Cooling Fans
When selecting the Bi-sonic BP1203824H-03 or similar industrial fans, consider these critical factors:
1. Voltage Compatibility: Ensure your power supply provides stable 24V DC. While this fan may operate at lower voltages with reduced performance, consistent 24V is required for optimal airflow and longevity.
2. Airflow Requirements: Calculate your thermal dissipation needs. For general electronics cooling, 120-150 CFM is suitable for most 19" rack applications. For high-heat components, consider multiple fans or higher-capacity models.
3. Space Constraints: The 120mm × 120mm × 38mm dimensions require proper clearance for installation and airflow. Allow at least 10-15mm clearance on the intake and exhaust sides for optimal performance.
4. Noise Considerations: At 35-45 dBA, this fan provides a balance between performance and acoustic output. For noise-sensitive environments, consider speed-controlled operation or additional acoustic damping.
5. Environmental Conditions: The -10°C to +70°C operating range makes this fan suitable for most indoor industrial applications. For extreme environments, consult the manufacturer's specifications for derating information.
6. Mounting Configuration: Standard screw mounting at all four corners. Ensure proper vibration isolation if mounting to sensitive equipment or in high-vibration environments.
7. Connector Compatibility: Verify your system's fan connector type (3-pin or 4-pin PWM) and ensure proper pin alignment before installation.
Frequently Asked Questions
Q1: Can this 24V fan be operated at 12V for reduced noise and airflow?
While possible, operating at 12V will significantly reduce airflow (approximately 50-60% of rated capacity) and may not provide sufficient cooling for intended applications. For variable speed control, consider using a PWM controller with the 24V supply.
Q2: What maintenance is required for the dual ball bearing system?
The dual ball bearing design is typically maintenance-free for the life of the fan. However, in dusty or contaminated environments, periodic cleaning of the fan blades and housing is recommended to maintain optimal performance. The bearings are sealed and lubricated for life.
Q3: How does this axial fan compare to centrifugal fans for restricted airflow applications?
Axial fans like the BP1203824H-03 excel at moving high volumes of air with minimal resistance. For applications with significant airflow restriction (dense heat sinks, long ducts, or filters), centrifugal fans typically provide higher static pressure. Evaluate your specific airflow path resistance when selecting between fan types.
