The Rittal SK 3241.708 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. As part of the Rittal Blue e+ enclosure climate control range, it combines powerful airflow with pressure-stable fan technology to support effective heat dissipation from industrial electrical and electronic equipment.
The SK 3241.708 is supplied as a complete unit for enclosure ventilation and features a high-performance pleated filter. Its tool-free mounting concept supports straightforward panel installation, while the accessible louvred grille simplifies routine filter maintenance. The RAL 9005 black finish makes this version particularly suitable for dark-coloured enclosures, machinery and equipment installations.
Operating from a 230 V single-phase, 50/60 Hz supply, the SK 3241.708 delivers an airflow of 272 m³/h at 50 Hz and 280 m³/h at 60 Hz. Its 255 × 255 × 129 mm housing and filtered ventilation design make it a powerful solution for industrial cabinets requiring greater forced-air cooling capacity.
Fan-and-filter units provide forced-air enclosure cooling by drawing cooler ambient air through filter media and circulating it across heat-generating components. This continuous exchange of air helps control internal temperatures and reduce thermal stress on PLCs, variable speed drives, power supplies, contactors and other industrial electronic equipment.
With airflow reaching 280 m³/h, the Rittal SK 3241.708 is particularly useful for enclosures with greater heat loads where natural convection is insufficient. Its Blue e+ design combines efficient filtered ventilation with straightforward installation and maintenance, providing a practical climate control solution for industrial machinery and automation systems.
