£22.21
The Rittal SK 3239.020 is a purpose-designed blanking cover for Rittal fan-and-filter units and outlet filters, providing a simple way to close an existing ventilation opening when airflow is no longer required. Designed for compatible Rittal SK 3239 series units, the cover replaces the filter mat without requiring welding or mechanical modification of the enclosure.
Manufactured from closed-cell PE, the SK 3239.020 provides a practical solution for adapting existing electrical enclosures while retaining an IP54 protection rating to IEC 60529. This allows redundant fan-and-filter or outlet-filter openings to be sealed without replacing the enclosure panel or carrying out additional sheet-metal work.
Measuring 167 × 167 × 15 mm, the SK 3239.020 is designed for Rittal SK 3239 series fan-and-filter units and outlet filters. Its anthracite construction provides a durable enclosure climate-control accessory for industrial control cabinets, automation systems and electrical installations.
Industrial electrical enclosures are frequently modified during equipment upgrades, machinery alterations or changes to cooling requirements. When an existing fan-and-filter unit or outlet filter is no longer required, leaving the ventilation path open can compromise the enclosure’s protection against environmental contamination.
The Rittal SK 3239.020 provides a straightforward way to close the opening by replacing the existing filter mat with a closed-cell PE blanking cover. This avoids welding or mechanical modification of the enclosure and enables the compatible assembly to achieve an IP54 protection rating, making it particularly useful for retrofit and maintenance applications.
