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.

Use SK 3243300 for a RAL 7035 light-grey outlet paired with a compatible Blue e+ SK 3243, SK 3244 or SK 3245 fan-and-filter unit from the ranges listed above. Its 323 × 323 mm outer face and 292 × 292 mm panel opening make it important to check the enclosure drawing and available mounting area.
The opening louvred grille gives access to the supplied pleated filter for regular inspection and replacement. Optimized snap hooks support tool-free fitting to the prepared cut-out. Check the filter more often where airborne dust could obstruct the ventilation path.
The pleated-filter arrangement is specified at IP54 and NEMA Type 12. Rittal lists IP55 with an additional absorber mat, and IP56 or NEMA Type 3/3R/4/4X with a suitable hose-proof hood and filter. Confirm the full assembly and the powered fan's capacity for the enclosure heat load.
| Article number | Use it when | Do not treat as interchangeable when |
|---|---|---|
| SK 3243300 | The matching fan is an SK 3243.7xx/.9xx, 3244.7xx/.9xx or 3245.9xx and the grille must be RAL 7035. | The finish must be RAL 9005 black or the fan belongs to another filter platform. |
| SK 3243308 | A listed Blue e+ fan needs the same 292 × 292 mm cut-out but a black RAL 9005 grille. | The enclosure design specifies the RAL 7035 light-grey outlet. |
| SK 3243200 | A standard outlet filter is specified for the older SK 3243.1xx/.5xx, 3244.1xx/.5xx or 3245.5xx fan family. | The design calls for the Blue e+ outlet and a matching .7xx/.9xx fan family. |
| Item | Relevant customer requirement |
|---|---|
| Pleated replacement filter | Inspect the pleated filter as site dust builds up. Confirm the correct replacement medium for the 323 mm Blue e+ outlet before ordering. |
| SK 3243.080 stainless steel hose-proof hood 350 × 480 × 110 mm |
For a specified IP56 or NEMA Type 3/3R/4/4X arrangement, check the complete filter-and-hood assembly and exterior clearance. Confirm hood compatibility for the precise fan family, especially SK 3245. |
| Absorber mat | Rittal specifies IP55 when a pleated filter is used with an absorber mat. Confirm the matching accessory and assembly requirements for the installation. |
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.
