Description
The ebm-papst 3258J/2HHP is a high-performance Tubeaxial Fan engineered for demanding thermal management applications requiring significant static pressure and airflow density. Utilizing advanced electronically commutated (EC) DC motor technology, this unit features a robust glass-fiber reinforced plastic housing (PBT) and impeller (PA) designed to maintain structural rigidity under high rotational velocities. The aerodynamic profile minimizes turbulence while optimizing thermal impedance reduction in dense electronic enclosures. Equipped with a maintenance-free ball bearing system and a 4-wire PWM interface, it offers precise speed regulation and extended service life, ensuring reliability in critical industrial environments where consistent cooling is mandatory for component longevity.

This cooling solution is specifically calibrated for high-density electronic assemblies such as telecommunications base stations, server rack cooling modules, and industrial power supply units. The 3258J/2HHP excels in environments where back-pressure is a limiting factor, effectively forcing air through tightly packed components to prevent thermal throttling. Additionally, the 3258J/2HHP is frequently utilized in medical instrumentation and CNC machinery control panels where consistent thermal regulation and variable speed control via PWM are paramount for operational stability.
