The Rittal SK 3245.600 is a high-capacity TopTherm EMC fan-and-filter unit designed for powerful filtered forced-air cooling of electrical enclosures while maintaining a high level of electromagnetic shielding and attenuation. Its EMC construction meets requirement category 2 to EN 61587-3, making it particularly suitable for industrial cabinets containing sensitive electronic, communication and automation equipment.
The SK 3245.600 combines a high-performance diagonal fan with an energy-efficient EC motor and a chopped-fibre filter mat. The complete unit is supplied ready for tool-free mounting into the enclosure surface, providing a practical solution for applications requiring both substantial cooling airflow and EMC-compatible ventilation.
Operating from a 200–240 V single-phase, 50/60 Hz supply, the current Rittal specification provides an unimpeded airflow of 890 m³/h at both 50 Hz and 60 Hz, closely corresponding to the nominal 900 m³/h rating associated with this model. With its chopped-fibre filter, the unit provides IP51 protection, while higher protection up to IP56 can be achieved using a compatible hose-proof hood.
Fan-and-filter units provide forced-air cooling by drawing cooler ambient air through filter media and circulating it across heat-generating electrical and electronic components. A suitably positioned outlet filter allows heated air to escape, creating continuous enclosure ventilation that helps reduce thermal stress on drives, PLCs, power electronics and other industrial equipment.
Ventilation openings can reduce the electromagnetic shielding effectiveness of an enclosure, which is particularly important in installations containing EMC-sensitive equipment. The Rittal SK 3245.600 combines high-volume filtered ventilation with dedicated EMC shielding and attenuation, providing an effective solution where both thermal management and electromagnetic compatibility are essential.
