The Rittal SK 3241.710 is a high-performance Blue e+ fan-and-filter unit designed to provide reliable filtered forced-air cooling for electrical enclosures, control panels and industrial automation systems. Its diagonal fan technology provides improved pressure stability and more constant airflow, helping achieve even heat dissipation throughout industrial control cabinets.
The SK 3241.710 is supplied as a complete unit ready for installation with a high-performance pleated filter. Optimised detent hooks enable fast, tool-free mounting into the enclosure surface, while the opening mechanism incorporated into the louvred grille simplifies routine filter replacement. The pleated filter supplied as standard provides maximum airflow performance while helping protect internal components against airborne contamination.
Operating from a 115 V single-phase, 50/60 Hz supply, the SK 3241.710 delivers an unimpeded airflow of 272 m³/h at 50 Hz and 280 m³/h at 60 Hz with its pleated filter. Its 255 × 255 × 129 mm RAL 7035 housing, IP54 protection and NEMA Type 12 rating make it a dependable solution for industrial enclosures requiring high-capacity filtered ventilation.
Fan-and-filter units provide forced-air enclosure cooling by drawing cooler ambient air through filter media and circulating it across heat-generating electrical and electronic components. This continuous exchange of air helps control internal temperatures, reduce thermal stress and support reliable operation of PLCs, variable speed drives, power supplies and other industrial control equipment.
The Rittal Blue e+ design uses diagonal fan technology for greater pressure stability and more constant ventilation throughout the enclosure. Combined with the high-performance pleated filter supplied with the SK 3241.710, this enables high airflow while helping reduce the ingress of dust and airborne particles, making the unit particularly suitable for industrial cabinets with significant thermal loads.
