## Summary description

Rittal SK 3239.400 is a replacement filter designed for ventilation and electromagnetic compatibility (EMC) applications. Supplied in grey with one unit per pack, it serves as a service part for enclosures and cabinets requiring air filtration and EMV attenuation. Suitable for maintenance and component replacement in industrial control cabinets.

## Long description

Rittal SK 3239.400 is an outlet filter designed for ventilation by convection in electrical enclosures and industrial control cabinets. The filter combines air filtration with electromagnetic compatibility (EMC) attenuation to reduce particulate ingress while helping to suppress electromagnetic interference. Supplied in grey (RAL 7035) and packaged as a single unit, this replacement part fits into the upper or lower outlet positions of compatible enclosures to support ventilation and service maintenance tasks.
Advantages
The outlet filter provides combined functions of ventilation and EMC attenuation in a single component, simplifying maintenance and replacement. Its compact design allows installation in the upper or lower sections of enclosures where convection-based airflow occurs. The neutral grey colour (RAL 7035) integrates with standard industrial cabinet finishes. As a service part, it enables straightforward replacement to maintain enclosure performance over time.
Suitable for
 Convection-ventilated electrical enclosures and control cabinets
 Applications requiring particulate filtration at enclosure outlets
 Environments where basic EMC attenuation at ventilation points is needed
 Routine maintenance and component replacement in industrial panels
When it may not be suitable
This outlet filter is intended for convection-based ventilation and provides basic EMC attenuation; it is not a substitute for active cooling systems such as fans or air conditioners. For enclosures with high heat loads or where precise temperature control is required, a dedicated cooling solution should be used. In installations demanding high-performance EMI/EMC shielding across all cabinet seams, additional shielding measures may be required beyond an outlet filter.
Key specifications
 Function: outlet filter for ventilation and electromagnetic compatibility (EMC attenuation)
 Colour: grey (RAL 7035)
 Packaging: single unit per pack
 Mounting position: suitable for upper or lower outlet positions in compatible enclosures
 Application: convection ventilation and particulate filtration at enclosure outlets
How to use
Fit the filter into the designated outlet slot of the enclosure in either the upper or lower section where convection flow is present. Ensure the mounting frame or retention features of the enclosure match the filter dimensions before insertion. Regularly inspect the filter for dust accumulation and replace it as part of scheduled maintenance to preserve airflow and EMC performance. Follow the enclosure manufacturer's instructions for removal and installation to avoid damage to the filter or cabinet seals.
What to consider before purchase
 Verify the outlet filter dimensions and mounting compatibility with your enclosure model
 Assess whether convection ventilation is sufficient for your heat dissipation needs
 Determine if the level of EMC attenuation provided by an outlet filter meets your application requirements
 Consider replacement frequency based on environmental dust levels and maintenance intervals
Usage recommendations
Install the filter in the outlet position corresponding to natural convection flow and replace it regularly when visible dust buildup reduces airflow. Combine with other EMC measures for improved shielding where required, and use active cooling if enclosure temperatures exceed recommended limits for internal components.
