## Summary description

Axial ball-bearing fan BLOW 40×20 mm 24V designed for cooling compact electronics and PC components. This 40×20 mm fan operates at 24V DC and uses a ball bearing for increased durability and longer service life. Suitable for ventilation of small enclosures, power supplies, routers, and embedded systems where reliable airflow and compact size are required.

## Long description

Axial ball-bearing fan BLOW 40×20 mm 24V is a compact cooling unit designed for targeted airflow in small electronic enclosures and PC components. The fan measures 40×20 mm and runs on 24V DC, using a ball-bearing rotor to provide stable operation and extended service life compared with sleeve-bearing alternatives. It is intended for applications that require reliable ventilation in limited spaces, such as power supplies, routers, embedded systems, and small chassis.
Advantages
The ball-bearing design delivers improved durability and consistent rotational stability across a wide temperature range, reducing maintenance intervals and the risk of premature failure. Its compact 40×20 mm form factor enables installation in tight locations where larger fans cannot fit, while the 24V operating voltage is compatible with many industrial and telecom power systems. The fan's straightforward axial airflow pattern provides effective ventilation for localized heat sources.
Suitable for
 Cooling power supplies and small transformers
 Ventilation of network equipment such as routers and switches
 Thermal management in embedded systems and control panels
 Supplemental airflow for compact PC cases or DIY electronics enclosures
Key specifications
 Type: axial fan with ball bearing
 Dimensions: 40 × 20 mm (diameter × thickness)
 Rated voltage: 24 V DC
 Form factor: compact, low-profile
 Airflow direction: axial (straight through)
 Typical applications: electronic enclosures, power supplies, routers, embedded devices
How to use
Install the fan in the intended chassis or enclosure using suitable mounting holes or brackets that match the 40×20 mm footprint. Ensure correct orientation for desired airflow direction and provide secure electrical connection to a stable 24V DC supply with appropriate wiring and polarity. Observe manufacturer-recommended clearances to avoid obstructing the intake or exhaust and to maintain optimal airflow. If a speed controller or PWM regulator is used, verify compatibility with a 24V ball-bearing fan to prevent undue stress on the motor.
Usage recommendations
For reliable long-term operation, mount the fan to minimize vibration transfer to the enclosure, keep intake and exhaust paths clear of dust and debris, and perform periodic inspections. In dusty environments, consider using a filter or implementing a maintenance schedule to prevent accumulation that can reduce cooling performance. Match the fan's airflow capacity to the heat dissipation needs of the component being cooled and ensure a stable 24V supply within the specified tolerance.
