The Rittal SK3239.124 is an AC fan-and-filter unit for enclosure cooling, supporting equipment thermal management and integration.
Data includes 24 V operation and airflow up to 105 m³/h for reviewing airflow capability against the resistance of the finished assembly. Its integrated motor and impeller support stable ventilation. Listed noise is 46 dB at the stated test point. A suitable electrical match and clean airflow entry reduce avoidable losses and support dependable long-term duty.
The SK3239.124 suits OEM integration and replacement sourcing; verify wiring, mounting, duty point and ambient limits before approval. This verified model profile provides an audit trail across service workflows before release to production.
Provide service access, keep the airflow path clean, inspect wiring and mounting, and investigate abnormal noise or vibration before continued use.
Correct sizing and operation within documented limits can reduce avoidable thermal stress and maintenance events; project savings require duty-cycle analysis.
The supplied comparison identifies a listed acoustic value of 46 dB; review it together with the other listed ratings rather than as a standalone selection criterion.
