Rittal SK3237.300 is a RAL 7035 Blue e+ wall-mounted outlet filter measuring 116.5 x 116.5 x 33.2 mm for compatible SK3237.7xx fan-and-filter units, supplied with a chopped-fibre filter mat.
£27.74
The Rittal SK3237.300 is a Blue e+ outlet filter designed for use with compatible Rittal SK3237.7xx fan-and-filter units. Working together with the corresponding fan-and-filter unit, it helps dissipate heat from electrical enclosures, ventilate the cabinet and protect temperature-sensitive electrical and electronic components.
The outlet filter allows ambient air to form part of an effective forced-air enclosure ventilation system, provided the surrounding air temperature is below the permissible internal enclosure temperature. A supplied chopped-fibre filter mat helps reduce the ingress of airborne contamination while maintaining the airflow path through the enclosure.
Manufactured from durable plastic in RAL 7035, the SK3237.300 measures 116.5 × 116.5 × 33.2 mm (W × H × D) and requires a 92 × 92 mm mounting cut-out. Optimised detent hooks and a tool-free mounting design support fast installation, while the louvred grille incorporates an opening mechanism for straightforward filter replacement.
The Rittal SK3237.300 works with a corresponding Blue e+ fan-and-filter unit to create a controlled airflow path through an electrical enclosure. Cooler ambient air is introduced into the cabinet while heated air is discharged through the ventilation system, helping maintain suitable operating conditions for temperature-sensitive components.
Its replaceable chopped-fibre filter mat helps reduce airborne contamination entering the ventilation path, while the tool-free design makes routine servicing straightforward. This combination makes the SK3237.300 a practical solution for control panels and automation enclosures where forced-air cooling provides sufficient thermal management.
