Why Choose a Blower Instead of an Axial Fan?

Many engineers automatically consider axial fans when designing cooling systems. However, there are situations where a blower offers significant advantages.

Unlike an axial fan that moves air straight through its frame, a blower redirects airflow by approximately 90 degrees. This design allows cooling air to be guided toward specific heat-generating components without requiring additional ducting structures.

This airflow characteristic is particularly beneficial when:

• Equipment has narrow airflow channels
• Heat sources are concentrated in one location
• Internal layouts are highly compact
• Air must be delivered to a targeted area
• System resistance is higher than normal

The 109BM24GC2-1 provides these advantages while maintaining a compact footprint suitable for space-constrained designs.

Balanced Airflow and Static Pressure

Thermal engineers often focus on airflow, but airflow alone does not determine cooling effectiveness.

The 109BM24GC2-1 delivers:

• 28.9 CFM maximum airflow
• 281 Pa maximum static pressure

These specifications provide a balanced combination of airflow volume and pressure capability.

In real-world applications, cooling air frequently encounters resistance from:

• Heat sinks
• Air filters
• Protective grills
• Internal chassis structures
• Dense circuit boards
• Cable routing systems

A blower with sufficient pressure capability can maintain airflow more effectively under these conditions compared with fans optimized solely for free-air airflow performance.

Suitable for Compact Electronics

The 97 × 33 mm dimensions make the 109BM24GC2-1 suitable for compact electronic equipment where installation space is limited.

Typical examples include:

Communication Equipment

Network switches, routers, optical transmission devices, and wireless communication systems often require controlled airflow within compact enclosures.

Industrial Control Systems

PLC cabinets, industrial controllers, and embedded computing systems generate heat continuously and benefit from reliable forced-air cooling.

Power Supply Equipment

Power conversion systems contain heat-generating components such as MOSFETs, IGBTs, transformers, and capacitors that require effective airflow management.

Medical Electronics

Many medical devices require compact cooling solutions while maintaining long-term operational reliability.

Instrumentation Equipment

Measurement and testing equipment frequently utilize blower fans to direct airflow toward critical internal components.

---

Low Power Consumption

With a rated power consumption of only 7.44 W, the 109BM24GC2-1 provides an efficient cooling solution for systems where power budget is an important design consideration.

Benefits of lower power consumption include:

• Reduced overall system energy usage
• Lower thermal contribution from the fan itself
• Improved power supply efficiency
• Reduced operating costs
• Simplified power management

For equipment operating continuously throughout the year, fan efficiency can have a measurable impact on total energy consumption.

---

Reliable Fan Monitoring

The blower includes a Pulse Sensor output.

This signal enables system designers to monitor fan operation in real time.

Common uses include:

• Fan speed monitoring
• Fault detection
• Predictive maintenance
• Thermal protection systems
• Remote equipment management

For mission-critical applications, fan monitoring helps improve overall system reliability by providing early warning of abnormal operating conditions.

---

Acoustic Performance

Cooling performance often comes at the expense of noise generation. The 109BM24GC2-1 achieves a maximum noise level of 51.5 dBA, making it quieter than many higher-speed blower models.

This makes the fan suitable for applications where a balance between cooling performance and acoustic comfort is desired.

Noise-sensitive applications may include:

• Office equipment
• Network equipment rooms
• Laboratory instruments
• Medical devices
• Indoor industrial systems

Actual noise levels will depend on enclosure design and airflow path characteristics.

---

Long Service Life

Reliability remains one of the defining characteristics of the San Ace series.

The expected service life of the 109BM24GC2-1 reaches:

• 40,000 hours at 60°C
• 70,000 hours at 40°C

Long-life operation helps reduce:

• Maintenance frequency
• Replacement costs
• Equipment downtime
• Service interruptions

This makes the blower suitable for systems expected to operate continuously over extended periods.

Thermal Design Considerations

When selecting a blower fan, engineers should evaluate more than airflow specifications alone.

Important considerations include:

Airflow Path Design

The cooling path should minimize unnecessary restrictions to maximize blower performance.

System Impedance

Understanding airflow resistance is essential for selecting the correct blower model.

Temperature Targets

Required airflow depends on acceptable component operating temperatures.

Reliability Requirements

Long-life applications should account for operating temperature and maintenance intervals.

Acoustic Requirements

Noise limits may influence blower selection and mounting strategy.

The 109BM24GC2-1 provides a practical balance of airflow, pressure, efficiency, and reliability for many electronic cooling designs.
