🔧 Operation
The fan uses a DC motor with ball bearings and a multi-blade impeller designed to generate high airflow through the system being cooled.
Power is supplied at 24 V DC, with operation possible within the 12–28 V DC range. The third conductor provides the tachometric signal, useful for verifying rotation and detecting possible fan anomalies.
The 6424/2HR reaches approximately 4,000 rpm and an airflow of approximately 460 m³/h, making it particularly suitable for cooling equipment with high thermal dissipation.
🏭 Applications
Thanks to its dimensions and high ventilation capacity, the ebm-papst 6424/2HR can be used for cooling:
- Inverters and power converters
- UPS and power supply systems
- Industrial electrical cabinets
- Power electronic equipment
- Automation systems
- Industrial power supplies
- Control and conversion systems
- Renewable-energy equipment
- Enclosures and electronic systems with forced ventilation
The presence of the tachometric signal is particularly useful in equipment that continuously monitors the ventilation status.
🏗️ Construction & Installation
The fan features a robust large black frame, with mounting holes distributed around the perimeter and a 3-conductor cable connection.
The dimensions of 172 × 150 × 51 mm should be carefully considered for replacement, checking both the available space and the position of the mounting points.
🛡️ Product Condition
The component is used and shows normal signs of use, dust, and light superficial marks visible in the photographs. The frame, impeller, and blades appear visually intact, with no obvious structural breaks.
Electrical operation and speed are not declared tested, unless specifically tested before sale. Before installation, it is recommended to check power supply, current consumption, rotation, bearing noise, and tachometric signal.
