Rittal SK3241.810 Blue e+ EMC fan-and-filter unit providing 225/245 m³/h filtered airflow from a 115 V single-phase 50/60 Hz supply with IP54 protection and EMC shielding for industrial enclosures.
£423.97
The Rittal SK3241.810 is a high-performance Blue e+ EMC fan-and-filter unit designed to provide reliable filtered ventilation while maintaining electromagnetic shielding in industrial electrical enclosures. Its EMC construction provides a high shielding and attenuation effect and meets requirement category 2 according to EN 61587-3, making it particularly suitable for sensitive automation, power electronics and communication equipment.
Operating from a 115 V AC single-phase, 50/60 Hz supply, the SK3241.810 delivers an unimpeded airflow of 225 m³/h at 50 Hz and 245 m³/h at 60 Hz with its chopped-fibre EMC filter. When combined with a matching outlet filter and chopped-fibre filter, the available airflow is approximately 173 m³/h at 50 Hz and 187 m³/h at 60 Hz.
Measuring 255 × 255 × 129 mm and finished in RAL 7035 light grey, the unit incorporates diagonal fan technology for improved pressure stability and more even enclosure ventilation. Tool-free mounting, optimised detent hooks and an easy-opening louvred grille simplify installation and filter maintenance, while IP54 protection supports dependable use in demanding industrial environments.
Electrical enclosures containing variable speed drives, PLCs, switching equipment and communication electronics often require both effective temperature management and electromagnetic shielding. The Rittal SK3241.810 draws filtered ambient air into the enclosure to remove internally generated heat while its EMC construction helps maintain the shielding characteristics required by sensitive industrial equipment.
Rittal's diagonal fan technology provides increased pressure stability for more even and consistent ventilation throughout the control cabinet. Combined with the supplied EMC filter mat and requirement category 2 performance according to EN 61587-3, the SK3241.810 provides an effective ventilation solution for industrial systems where thermal management and electromagnetic compatibility are both important.
