The outlet filter is used in conjunction with the corresponding fan-and-filter unit to dissipate heat loss from enclosures, ventilate the enclosure and protect temperature-sensitive components. This is achieved through the direct infeed of ambient air, the temperature of which must be lower than the permissible internal temperature of the enclosure.

The Rittal Blue e+ outlet filter SK 3237300 is intended for enclosure ventilation systems using a matching SK 3237.7xx fan-and-filter unit. As the passive exhaust side of the airflow path, it is a practical choice for panel builders and maintenance teams that need filtered air discharge without adding another powered fan. Tool-free mounting helps simplify installation, while the opening louvred grille gives technicians easier access to the filter mat during routine maintenance. For applications where enclosure protection is important, the standard filter configuration supports IP54 and NEMA Type 12 requirements.

SK 3237300 is suited to control cabinets and industrial enclosures using a Blue e+ SK 3237.7xx fan-and-filter unit where a passive exhaust opening is required. The 92 × 92 mm mounting cut-out makes it particularly relevant for new cabinet builds or replacement work already designed around this opening size.
It is a practical choice when maintenance access matters. The snap-in mounting avoids separate fastening hardware during installation, while the opening louvred grille gives technicians direct access to the filter mat during routine service.
For installations requiring IP54 or NEMA Type 12 protection, the supplied chopped-fibre filter mat can be used in the standard configuration. Where hose-directed water is part of the operating or cleaning environment, the installation should instead be evaluated with the appropriate hose-proof hood for the required IP56 or NEMA Type 3/3R arrangement.
| Article number | Use it when | Do not treat as interchangeable when |
|---|---|---|
| SK 3237300 | The powered unit belongs to the Blue e+ SK 3237.7xx family and EMC shielding is not required. | The system uses an EMC fan or a different SK 3237 platform. |
| SK 3237400 | The matching fan belongs to the SK 3237.8xx EMC range. | The project does not use the corresponding EMC arrangement. |
| SK 3237200 | The system uses the Standard SK 3237.1xx platform and the 16 mm-deep outlet filter is specified. | The powered fan is from the Blue e+ SK 3237.7xx family. |
| Item | Relevant customer requirement |
|---|---|
| SK 3237054 chopped-fibre filter mat 89 × 89 × 10 mm; pack of 5 |
Replacement media for the non-EMC SK 3237.3xx/3237.7xx platform. Set the inspection interval from the site's dust load rather than waiting for visible blockage or cabinet temperature rise. |
| SK 3237080 stainless steel hose-proof hood 150 × 230 × 40 mm |
Use when the completed installation must reach IP56 or when the outlet needs additional protection against hose-directed water. Reserve the larger external footprint before cutting the enclosure. |
For model confirmation or quotation, send: the powered fan article number, enclosure heat loss, maximum ambient temperature, permitted internal temperature, required IP/NEMA rating, installation drawing, quantity and delivery destination. These details allow the outlet, airflow and protection arrangement to be checked together.
