The product is a DC fan from the brand PAPST, designed for integration into technical device concepts. It features brushless motor technology with an electronically commutated outer rotor motor, ensuring high operational reliability and long service life. The commutation electronics are fully integrated into the fan, enabling a compact design. The fan is intended for use in devices requiring reliable and quiet cooling, for example in electronic enclosures, measuring instruments, or industrial controls.

Applications

The fan is suitable for use in enclosed device housings where continuous air circulation is required. Due to its brushless technology, it is particularly suitable for applications requiring high service life and low maintenance. The integrated reverse polarity protection prevents the fan from starting with incorrect power supply, increasing operational safety. The protection function against blocking and overload via impedance protection ensures that the fan is not damaged in case of mechanical obstructions or current overloads.

Functions and Equipment in Detail

The fan consists of a housing made of glass-fiber-reinforced plastic, specifically from the material PBT, known for its high mechanical strength and heat resistance. The impeller is made of polyamide (PA), ensuring high abrasion resistance and dimensional stability. Airflow occurs via vanes, achieving uniform and efficient air guidance. The rotor rotation direction, viewed from the rotor side, is left-hand rotating, which must be considered during installation to achieve the desired airflow.

Technology Explained Simply

Brushless technology (DC fan) enables more efficient energy conversion and reduces mechanical wear, as no brushes need to be replaced due to wear. Electronic commutation is performed via integrated circuits that control the current supply to the motor, ensuring precise speed control and high operational reliability. Reverse polarity protection prevents the fan from starting when incorrectly polarized, helping to avoid damage to the motor or power supply. Impedance protection safeguards the fan against overloads, for example, if the impeller is blocked.

Compatibility and Accessories

The fan is designed for use in devices that allow power supply via two individual wires. The connection wires have a cross-section designation AWG 28 and comply with standard TR 64. The wire ends are stripped and tinned, enabling a secure and long-lasting electrical connection. The specified materials and construction properties make the fan compatible with a wide range of device housings, particularly in industrial electronics and measurement technology.

Mounting and Installation

Mounting is carried out into the respective device housing, taking into account the airflow direction (blowing through vanes) and rotation direction (left-hand rotating). The connection wires allow for easy electrical connection, with the tinning of the ends ensuring secure contact. The fan dimensions are 1500 mm length, 30 mm width, and 6 mm height, which must be considered when planning the mounting space.

Operational Advantages

The fan offers high operational reliability due to integrated protection functions against reverse polarity and overload. Brushless technology ensures long service life and low maintenance. The materials PBT and PA provide high mechanical stability and heat resistance, enabling use in demanding environments. The compact design and integrated electronics facilitate integration into existing device concepts.
