Rittal SK3240.800 Blue e+ EMC fan-and-filter unit providing 175/157 m³/h filtered airflow from a 230 V single-phase 50/60 Hz supply with IP54 protection and EMC shielding for industrial enclosures.
£323.09
The Rittal SK3240.800 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 design provides a high shielding and attenuation effect and meets requirement category 2 according to EN 61587-3, making it particularly suitable for sensitive electronic and automation installations.
Operating from a 230 V AC single-phase, 50/60 Hz supply, the SK3240.800 delivers an unimpeded airflow of 175 m³/h at 50 Hz and 157 m³/h at 60 Hz with its EMC chopped-fibre filter. When paired with the corresponding outlet filter, airflow is approximately 130 m³/h at 50 Hz and 112 m³/h at 60 Hz.
Measuring 255 × 255 × 129 mm and finished in RAL 7035 light grey, the unit features Rittal diagonal fan technology for improved pressure stability and more uniform enclosure ventilation. Tool-free mounting, optimised detent hooks and an easy-opening louvred grille simplify installation and filter maintenance, while standard IP54 protection supports dependable operation in industrial environments.
Electrical enclosures containing drives, PLCs, power electronics and communication equipment often require both effective heat dissipation and protection against electromagnetic interference. The Rittal SK3240.800 combines forced-air ventilation with EMC shielding, allowing filtered ambient air to cool enclosure components while helping maintain the shielding performance of the installation.
Rittal's diagonal fan technology improves pressure stability to promote more even and consistent ventilation throughout the enclosure. Combined with the supplied EMC filter mat and requirement category 2 performance according to EN 61587-3, the SK3240.800 provides a practical cooling solution for sensitive industrial electronics and automation systems.
