Axial Fan BLOW 85-811, 80×25 mm, 230 V, ball bearing, terminal connection

Axial fan BLOW 85-811 is a compact 80×25 mm mains-powered cooling unit designed for continuous operation at 230 V. The fan features a ball bearing for extended service life and a terminal connection for easy and safe wiring. It is intended for ventilation, cooling of electronic components and small enclosures where a compact footprint and reliable airflow at line voltage are required.

Advantages

The ball bearing design provides improved durability and stable operation during prolonged use. The 80×25 mm frame combines small dimensions with sufficient airflow for targeted cooling tasks. Terminal connection simplifies installation in equipment and control cabinets without the need for special connectors. Operating directly from 230 V mains reduces the need for intermediate power supplies in standard installations.

Suitable for

• Cooling electronic circuit boards and power supplies in small enclosures
• Ventilation of control cabinets and industrial housings
• Replacement or upgrade of existing 80 mm axial fans running on mains voltage
• Cooling of compact equipment such as chargers, inverters, and small appliances

Key specifications

• Frame size: 80 × 25 mm
• Operating voltage: 230 V AC
• Bearing type: ball bearing for extended lifespan
• Connection: fixed terminal block for secure wiring
• Mounting style: panel or enclosure mounting with screw holes (standard 80 mm pattern)
• Intended use: axial airflow for ventilation and cooling of compact spaces

How to use

Mount the fan in the enclosure or panel using the appropriate screws aligned with the standard 80 mm mounting pattern. Connect the supply wires to the terminal block, ensuring the mains voltage is switched off before wiring and observing correct polarity and grounding where applicable. Allow for unobstructed airflow through the intake and exhaust sides, and ensure adequate clearance from nearby components to prevent recirculation and heat buildup. After installation, verify rotation and airflow direction and confirm electrical safety before putting the equipment into continuous operation.

Usage recommendations

For reliable long-term performance, install the fan in a dust-protected location or use a filter if the ambient environment is dusty. Regularly inspect and clean the fan and terminal connections during scheduled maintenance intervals. Do not operate the unit outside its rated voltage and avoid mounting in locations with excessive vibration or direct exposure to liquids.
