Rittal SK 3245.800 Blue e+ EMC fan-and-filter unit for industrial enclosure cooling, providing 931 m³/h airflow from a 200-240 V single-phase supply with an EC motor, EMC shielding, intelligent control interfaces and a 323 x 323 x 161 mm RAL 7035 housing.

The Rittal SK 3245.800 is a high-capacity Blue e+ EMC fan-and-filter unit designed to provide powerful filtered forced-air cooling while helping preserve the electromagnetic shielding of industrial electrical enclosures. Rittal specifies a high shielding and attenuation effect meeting requirement category 2 to EN 61587-3, making the unit particularly suitable for cabinets containing sensitive automation, communication and electronic equipment.
The SK 3245.800 combines a diagonal fan with an energy-efficient EC motor and an EMC filter mat. Diagonal fan technology provides improved pressure stability for more even and consistent enclosure ventilation, while optimised detent hooks allow fast, tool-free installation. A convenient opening mechanism on the louvred grille also simplifies routine filter inspection and replacement.
Operating from a 200–240 V single-phase, 50/60 Hz supply, the SK 3245.800 provides an unimpeded airflow of 931 m³/h with its EMC filter mat. Its 323 × 323 × 161 mm RAL 7035 housing, integrated EC control interfaces and EMC construction make it a powerful enclosure climate control solution where high airflow, energy efficiency and electromagnetic compatibility are all important.
Fan-and-filter units provide forced-air enclosure cooling by drawing cooler ambient air through filter media and circulating it across heat-generating components. A suitably positioned outlet filter allows heated air to leave the cabinet, creating continuous airflow that helps control internal temperatures and reduce thermal stress on PLCs, drives, power electronics and other industrial equipment.
Ventilation openings can compromise the electromagnetic shielding of an enclosure, particularly where sensitive electronic equipment is installed. The Rittal SK 3245.800 addresses both requirements by combining 931 m³/h airflow with EMC shielding and an EC fan platform offering control, speed feedback, fault signalling and RS485 communication. This makes it particularly suitable for demanding applications where thermal management and electromagnetic compatibility must be considered together.
