SK3322.107 Rittal 230VAC 148.5×148.5mm Fan-and-Filter Unit

Description

Rittal SK3322.107 is a 230VAC 148.5×148.5mm Axial Fan-and-Filter Unit optimized for thermal management in high-density electrical enclosures. This industrial-grade cooling solution utilizes an ebmpapst motor assembly featuring a robust AC external rotor design and high-precision bearing architecture to ensure long-term structural rigidity. The unit is engineered to minimize thermal impedance within control cabinets by providing consistent laminar airflow through a specialized filter medium. Operating at 19W with a rated current of 12mA at 50Hz, this fan-and-filter unit maintains critical internal temperatures while offering scalable ingress protection up to IP56 with optional accessories. Its aerodynamic housing is designed for rapid tool-free installation, ensuring efficient heat dissipation in demanding industrial environments.
