Axial Ventilation Fan BLOW 8975# 120×120×30 mm 12V Sleeve Bearing

Axial ventilation fan BLOW 8975# is a compact 120×120×30 mm cooling fan designed for forced air circulation in electronic equipment, electrical enclosures, power supplies and ventilation systems. The fan operates on a 12 V supply and uses a sleeve (slip) bearing, offering a simple, low-cost solution for continuous use where moderate airflow and low power consumption are required. Its panel-mountable form factor makes it suitable for installation in apparatus panels and cabinets with limited depth.

Advantages

The sleeve bearing construction gives the fan a straightforward mechanical design with reduced manufacturing complexity and lower purchase cost compared with more complex bearing types. The 120×120×30 mm size balances airflow and installation space, enabling effective heat removal from electronics while fitting standard mounting cutouts. Operating at 12 V makes the fan compatible with common DC systems and many power supply designs. The compact profile and mounting arrangement support straightforward replacement or retrofit in existing enclosures.

Suitable for

• Cooling of electronic circuit boards and power supplies
• Air circulation in electrical enclosures and cabinets
• Ventilation in small equipment housings and control panels
• Low-to-moderate airflow cooling applications requiring continuous operation

Key specifications

• Overall dimensions: 120 × 120 × 30 mm
• Supply voltage: 12 V DC
• Bearing type: sleeve (slip) bearing
• Mounting: panel/enclosure mountable with standard screw holes
• Application: axial forced-air circulation for electronics and enclosures

How to use

Install the fan in a suitable panel or enclosure cutout using matching screw holes; ensure the airflow direction aligns with the intended ventilation path. Connect the fan to a stable 12 V DC source observing correct polarity. Provide appropriate electrical protection such as a fuse or current-limiting device according to the host equipment requirements. Allow clearance around the fan intake and outlet to avoid airflow obstruction and to maintain cooling efficiency. Because the fan uses a sleeve bearing, orient it according to the manufacturer’s guidance for longest life when continuous operation is required.

Usage recommendations

For reliable long-term performance, keep the fan and surrounding vents free of dust and debris. In dusty or high-temperature environments consider periodic inspection and replacement intervals consistent with sleeve-bearing maintenance characteristics. If lower noise, higher reliability, or extended service life is required, evaluate versions with different bearing types.
