Axial fan Papst 8412 NLE 12 V DC 33 m³/h 80×80×25 mm

The Axial fan Papst 8412 NLE 12 V DC 33 m³/h 80×80×25 mm is a compact cooling solution intended for low-voltage DC systems. With an 80×80×25 mm frame and axial airflow design, this fan is engineered to provide steady ventilation in electronics assemblies, small enclosures and auxiliary PC cooling setups. Its nominal supply voltage is 12 V DC and it achieves an airflow rate of up to 33 m³/h, making it suitable for applications where space is limited and reliable air movement is required.

Advantages

The fan’s compact 80×80×25 mm form factor allows straightforward integration into small devices and standard fan mounts. Operating from a 12 V DC supply, it is compatible with common embedded systems and power supply rails. The axial design delivers directed airflow of up to 33 m³/h, providing effective heat removal for low- to moderate-heat-density components. The unit’s standardized dimensions and mounting pattern simplify replacement and upgrades in existing setups.

Suitable for

• Cooling electronics inside small enclosures and control cabinets
• Auxiliary CPU/PC ventilation and case airflow support
• Power supply and embedded system component cooling
• Industrial control panels and telecommunications equipment ventilation

Key specifications

• Frame size: 80 × 80 × 25 mm
• Fan type: axial
• Rated voltage: 12 V DC
• Maximum airflow: 33 m³/h
• Typical mounting: four-hole square pattern compatible with 80 mm fan mounts

How to use

Install the fan in the intended enclosure or device using the standard four mounting points and secure it with appropriate screws or vibration-damping fasteners. Connect to a stable 12 V DC source observing correct polarity and any device-specific wiring requirements. Ensure the airflow orientation matches the cooling strategy—intake or exhaust—by verifying the fan’s airflow direction. Maintain clearance around the fan intake and outlet to avoid obstructing air movement and to preserve rated airflow performance.

Usage recommendations

For reliable operation, operate the fan at its rated 12 V DC supply and avoid prolonged exposure to dust and conductive contaminants. If used in dusty or industrial environments, consider adding a dust filter and schedule periodic cleaning to maintain airflow near the specified 33 m³/h. When integrating into PC or embedded systems, verify airflow direction relative to other cooling components to achieve effective heat dissipation.
