Filter Rittal SK 3238.300 — plastic housing, grey, 161 g, 1 pc

Rittal SK 3238.300 outlet filter is intended for use in industrial enclosures and ventilation systems where passive airflow by convection is used. The unit features a grey plastic housing and a lightweight construction of approximately 161 g. It is supplied as a single piece and is designed to be mounted in the upper or lower sections of a control cabinet or enclosure to help prevent dust and particulates from entering while preserving natural ventilation.

Advantages

The plastic housing ensures corrosion resistance and reduces weight compared with metal alternatives. The compact, single-piece design simplifies installation and maintenance. The filter element provides a barrier against dust and larger particulates without obstructing convection airflows, helping to maintain stable internal temperatures in enclosures that rely on passive ventilation.

Key specifications

How to use

Install the filter in the designated outlet opening of the enclosure, either at the top or bottom, according to the enclosure's ventilation scheme. Ensure the mounting area is clean and the filter sits flush to create an effective seal against unfiltered air ingress. Periodically inspect the filter for dust accumulation and replace or clean it as required to maintain airflow and protective performance.

Recommendations

For enclosures relying on natural convection, fit outlet filters both in upper and lower positions where appropriate to optimise airflow and particulate protection. Check compatibility with the enclosure opening dimensions before installation and perform regular visual inspections to prevent clogging and reduced ventilation efficiency.
