Why Choose the Rittal SK3240.800 Blue e+ EMC Fan-and-Filter Unit?
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.
