The Rittal SK3241.800 is a high-performance Blue e+ EMC fan-and-filter unit designed to provide filtered forced-air cooling while supporting electromagnetic compatibility in industrial electrical enclosures. It is particularly suited to control cabinets containing sensitive automation, power electronics and communication equipment where both effective heat dissipation and EMC performance are important.
Operating from a 230 V AC single-phase, 50/60 Hz supply, the SK3241.800 delivers an airflow of 225 m³/h at 50 Hz and 245 m³/h at 60 Hz. The Blue e+ fan-and-filter concept provides reliable enclosure ventilation while the EMC design helps preserve the shielding characteristics of appropriately constructed industrial cabinets.
Measuring 255 × 255 × 129 mm and finished in RAL 7035 light grey, the SK3241.800 provides a compact solution for enclosure climate control. Its integrated fan and filter arrangement helps protect internal components against airborne contamination while maintaining the airflow required to remove internally generated heat.
Electrical enclosures containing variable speed drives, switching equipment, PLCs and communication electronics can require both effective temperature management and electromagnetic shielding. The Rittal SK3241.800 draws filtered ambient air into the cabinet to remove internally generated heat while its EMC-compatible construction supports the shielding concept of the enclosure.
With airflow of up to 245 m³/h, the unit is suitable for industrial cabinets with significant ventilation requirements. When combined with a compatible EMC outlet filter and correctly installed within an appropriately shielded enclosure, it provides controlled airflow while helping maintain the electromagnetic compatibility required by sensitive industrial equipment.
