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 reliability and long service life. The integrated commutation electronics ensure that the fan only starts with correct polarity, which is guaranteed by electronic reverse polarity protection. This prevents damage to the device in case of incorrect connection. Additionally, the fan is protected against blocking and overload by an impedance protection, which automatically shuts off the motor under unusual load conditions to prevent damage.

Housing and impeller are made of high-quality plastics: the housing from PBT (polybutylene terephthalate), a thermoplastic polymer with high heat and chemical resistance, and the impeller from PA (polyamide), known for its mechanical strength and heat resistance. The fan is constructed as blowing over ribs, meaning that air is directed through the lateral ribs of the housing to ensure uniform and efficient airflow. The rotation direction is left-hand relative to the rotor, which must be considered during installation to achieve the desired airflow.

The dimensions of the fan are 2000 mm length, 40 mm width, and 8 mm height. This specific design is suitable for use in narrow or flat device housings where compact cooling is required. The use of glass-fibre-reinforced plastic ensures high mechanical stability with low weight, facilitating integration into sensitive systems. The electrical connection is made via two single conductors, designed for a secure and durable connection.

The fan is intended for use in industrial and technical applications where reliable cooling of electronic components is required. The combination of brushless technology, integrated protection functions, and robust material construction makes it particularly suitable for continuous operation in demanding environments. The specific design with dimensions 2000 x 40 x 8 mm allows flexible mounting in various device constructions, especially in flat or narrow housings.

Technology explained clearly: Electronic commutation replaces mechanical brushes, which wear out in conventional fans and require maintenance. This makes the fan maintenance-free and long-lasting. Reverse polarity protection prevents damage if the fan is connected with incorrect polarity. Impedance protection safeguards the motor against overload, for example if the fan becomes blocked. Materials PBT and PA are designed for high mechanical load capacity and heat resistance, increasing the fan's service life. Airflow over ribs ensures uniform and efficient cooling.

Compatibility and accessories: The fan is designed for use in electronic devices and technical systems where compact and quiet cooling is required. It can be integrated into device housings with corresponding dimensions. The use of AWG 28 conductors allows flexible wiring that can be adapted to existing systems.

Mounting and installation: Mounting is done into the device housing, taking into account the dimensions 2000 x 40 x 8 mm. The electrical connection is made via the two single conductors AWG 28, TR 64, which are stripped and tinned. The rotation direction is left-hand when viewed at the rotor, which must be considered during installation to achieve the desired airflow. The use of glass-fibre-reinforced plastic ensures stable mounting without additional fastening elements.

Operational advantages: The fan offers high operational reliability due to integrated protection functions, long service life due to brushless technology, and quiet operation. The robust material selection ensures high mechanical stability and heat resistance. The compact design enables flexible integration into various device constructions, especially in flat or narrow housings. The electrical connection via AWG 28 conductors is simple and reliable.
