Rittal SK 3243.400 Blue e+ EMC outlet filter for compatible SK 3243.8xx, SK 3244.8xx and SK 3245.8xx fan-and-filter units, featuring an EMC filter mat and a 323 x 323 mm RAL 7035 housing for filtered industrial enclosure ventilation.

The Rittal SK 3243.400 is a purpose-designed Blue e+ EMC outlet filter for use with compatible Rittal SK 3243.8xx, SK 3244.8xx and SK 3245.8xx EMC fan-and-filter units. It provides a filtered outlet path for enclosure ventilation systems while helping maintain the electromagnetic shielding performance required around ventilation openings in industrial electrical cabinets.
Designed for wall-mounted EMC applications, the SK 3243.400 combines a robust plastic grille with an EMC filter mat. The filter mat helps reduce the ingress of dust and airborne contamination while the EMC construction supports high shielding and attenuation performance, making the outlet filter particularly suitable for enclosures containing sensitive electronic and automation equipment.
With external dimensions of 323 × 323 mm and a RAL 7035 light-grey finish, the SK 3243.400 integrates neatly with compatible Rittal enclosure systems. When used as part of a correctly configured fan-and-filter ventilation system, it provides an effective passive air outlet while supporting both enclosure protection and electromagnetic compatibility.
Forced-air enclosure cooling works most effectively when the fan-and-filter unit is combined with a correctly sized outlet filter. The outlet provides a controlled path for heated air to leave the enclosure, helping maintain effective circulation across PLCs, drives, power supplies and other heat-generating components without requiring a second powered fan.
In EMC-sensitive applications, ordinary ventilation openings can reduce the shielding effectiveness of an enclosure. The Rittal SK 3243.400 addresses this requirement by combining filtered ventilation with EMC functionality, making it a suitable companion to compatible Rittal EMC fan-and-filter units where both thermal management and electromagnetic compatibility are important.

The SK 3243.400 is an EMC outlet filter used to provide a passive filtered air outlet for compatible Rittal fan-and-filter systems while helping maintain electromagnetic shielding around the enclosure ventilation opening.
The SK 3243.400 is designed for use with compatible Rittal SK 3243.8xx, SK 3244.8xx and SK 3245.8xx EMC fan-and-filter units.
The outlet filter measures 323 mm wide × 323 mm high and is designed for installation in a 292 × 292 mm mounting cut-out.
No. The SK 3243.400 is a passive outlet filter and therefore requires no separate electrical supply or wiring.
An EMC outlet filter is designed to provide the required ventilation path while also helping preserve the enclosure's electromagnetic shielding and attenuation performance, making it preferable for cabinets containing EMC-sensitive equipment.
Rittal EMC outlet filters combine effective filtered ventilation with electromagnetic shielding functionality, providing a practical air outlet for industrial enclosures where reliable thermal management and EMC performance are both essential.
