Model SK3140.500 is positioned as the Rittal AC compact axial fan for industrial machinery and control cabinets, supporting air movement where passive convection cannot maintain the required temperature margin.
OEM qualification should connect the fan choice to enclosure resistance, acoustic limits and the expected operating environment.
The thermal role must be validated from the approved datasheet because the reference does not establish every configuration detail.
The stated 400×133×400 mm size enables early mechanical-envelope and mounting checks. Check environmental limits in the original product data. Confirm the exact operating point before production release. Preserve the specified air movement direction during assembly.
Check electrical supply, mounting clearance, fasteners, airflow direction, guards, wiring, and access for service before installation.
No quantified cost-saving claim is supplied for this exact item. Compare energy use, controls, service needs, and purchase cost using the required duty point.
The product is classified as a compact axial fan. Use the full model code because nearby variants can differ in motor, mounting, and controls.
Verify the listed size, mounting pattern, fan housing or nozzle arrangement, airflow direction, and service clearance against the equipment drawing.
Check supply voltage, controller signals, blocked airflow, contamination, abnormal noise, rotation, and the equipment operating point before replacing the unit.
The matched source highlights a 400×133×400 mm size specified in the upload data. Compare that point together with the listed electrical and dimensional data.
