The product is a DC fan from the brand PAPST, manufactured from glass-fibre-reinforced plastic, with a housing made of PBT and an impeller made of PA. It is designed for integration into electronic devices and technical systems where reliable and quiet cooling is required. The fan features an electronically commutated outer rotor motor, in which the commutation electronics are fully integrated into the device. This technology enables efficient and maintenance-free operation, as there are no mechanical brushes that could wear out. The operating voltage is supplied via two single conductors AWG 28, TR 64, whose ends are stripped and tinned to ensure a secure electrical connection.

DC fan with electronically commutated outer rotor motor offers high operational safety and longevity. The integrated commutation electronics ensure precise speed control and prevent unwanted vibrations or noise. The electronic reverse polarity protection ensures that the fan only operates when the connection wires are correctly polarized, preventing damage to the motor or connected electronics. Additionally, an impedance protection safeguards the fan against blockages and overloads by automatically interrupting operation in case of unusually high resistance or mechanical obstruction.

Housing made of PBT and impeller made of PA ensure high mechanical stability and resistance to environmental influences. The material is suitable for use in industrial and technical applications where high temperatures, mechanical stress, or chemical exposure may occur. Airflow is directed via vanes, ensuring uniform and directed air guidance. The rotation direction of the fan is left-hand relative to the rotor, which must be considered during installation to achieve the desired airflow direction.

The fan is designed for use in compact devices and systems where space and performance are critical. Dimensions are 3000 mm length, 40 mm width, and 8 mm height, indicating a specific application in elongated or narrow assemblies. The construction is designed to integrate seamlessly into existing device concepts without requiring additional space or mechanical modifications.

The electrical connection method via two single conductors AWG 28, TR 64, enables flexible and secure connection to control or power supply modules. The stripped and tinned conductor ends facilitate installation and ensure a reliable contact, even during frequent assembly and disassembly. The use of PBT and PA as materials ensures high thermal and mechanical load capacity, making the fan suitable for industrial environments.

Operational advantages include long service life, low noise emission, and high reliability. The brushless technology reduces maintenance and extends operational life, as there are no mechanical wear parts. The integrated protection functions ensure safe and stable operation, even under demanding conditions. The fan is thus suitable for applications requiring continuous and reliable cooling without additional protective measures or maintenance intervals.

Compatibility with existing systems is ensured by standardizing the connection wires and mechanical dimensions. The use of PBT and PA as materials enables integration into various device designs, particularly in electronic and industrial devices where high thermal and mechanical loads occur. The specific rotation direction and airflow via vanes are optimized for maximum cooling performance in predefined assemblies.

Mounting and installation are performed by mechanical fastening to the designated mounting points of the device. The connection wires are attached to the corresponding power supply lines, with the electronic reverse polarity protection ensuring the fan only operates when correctly polarized. The dimensions and material of the housing allow for easy integration into existing constructions without requiring additional modifications or tools.
