Product information

Description

The BLOW axial cooling fan 40×20 mm is a compact 12V DC fan with a sliding (sleeve) bearing designed for targeted airflow in tight spaces. Its low-profile 40 mm × 20 mm frame makes it suitable for applications where space is limited and a reliable small form-factor fan is required. The fan is intended to move air across electronic components, helping to reduce operating temperatures in assemblies such as power supplies, network devices and control electronics.

Advantages

This 12V sliding-bearing axial fan offers a small footprint and straightforward mechanical integration into enclosures and PCBs. The sliding (sleeve) bearing provides smooth operation at typical operating voltages and allows for continuous airflow in compact designs. Its size and voltage compatibility make it an economical choice for localized cooling, delivering directed air movement for improved heat dissipation without adding significant bulk or complexity.

Suitable for

  • Cooling small enclosures and chassis with limited clearance
  • Cooling PCBs and electronic modules where spot airflow is required
  • Ventilation in power supplies, routers and networking equipment
  • Cooling of industrial controllers and small automation devices

Key specifications

  • Frame dimensions: 40 × 20 mm
  • Operating voltage: 12 V DC
  • Bearing type: sliding (sleeve) bearing
  • Axial fan construction for directional airflow
  • Low-profile design for limited-space installations

How to use

Mount the fan securely to a compatible surface or bracket using the appropriate screws or fixtures for the 40×20 mm housing. Connect the fan to a stable 12V DC supply observing correct polarity. Ensure the airflow direction aligns with the intended cooling path and that intake and exhaust openings are not obstructed. For PCB-mounted installations, allow clearance for the fan and any connector leads, and secure wiring to prevent strain on terminals.

Usage recommendations

Use the fan in environments with moderate ambient temperatures and avoid prolonged exposure to dust and moisture. Periodic inspection and cleaning of the fan blades and housing will help maintain airflow performance. If quieter operation or higher durability is required, consider fans with ball bearings or higher IP-rating enclosures for harsher environments.
