FB050-4DK.4I.V4P 125331 is a 400 VAC axial fan for chillers, cold-chain equipment, industrial refrigeration. Its main supplied feature is 1340 rpm rated speed in the supplied parameter row. It also lists a 500 mm size specified in the upload data. Review fan selection for installation planning.
FB050-4DK.4I.V4P 125331 positions the ZIEHL-ABEGG AC axial fan for chillers, cold-chain and refrigeration equipment. It helps move heat away from critical components and supports predictable equipment temperatures throughout the duty cycle.
A 400 VAC rating with 650 W input helps engineers plan the electrical supply and cooling-energy budget. The aerodynamic structure supports efficient airflow with stable rotational behavior. Correct installation helps preserve cooling capacity, control vibration and reduce avoidable noise over long operating cycles.
System qualification for FB050-4DK.4I.V4P 125331 should use the final grille, nozzle and surrounding equipment structure. This helps manufacturers preserve useful airflow, manage sound and define compatible replacements.
ZIEHL-ABEGG FB050-4DK.4I.V4P 125331 addresses airflow needs in full inlet-ring and ducted-air installations and moves air through engineered duct systems with defined inlet and discharge boundaries. The selection can be qualified against the finished system resistance and the expected duty cycle.
For OEM selection, the AC axial fan gives engineers a defined component for prototype validation and series sourcing. OEM designs for chillers and heat-pump systems can use ZIEHL-ABEGG FB050-4DK.4I.V4P 125331; the unit draws heat through condenser or heat-exchange sections in chiller equipment.
FB050-4DK.4I.V4P 125331 supports cold-chain, refrigerated display and storage equipment. In this duty, it helps reduce temperature variation around stored goods and cooling components. The equipment relies on forced airflow to supplement the limited cooling available from natural convection.
Reliable circulation is important here because compact assemblies leave limited space for passive heat dissipation. Industrial refrigeration and compressor equipment use FB050-4DK.4I.V4P 125331 where the AC axial fan supports stable temperatures around condensers, compressors and control sections.
The matched source highlights 1340 rpm rated speed in the supplied parameter row. Compare that point together with the listed electrical and dimensional data.
Its advantage should be judged from the matched series feature, exact size, electrical rating, and available performance data rather than from a generic fan comparison.
The supplied files do not establish a universal 24/7 duty rating. Validate ambient conditions, duty cycle, protection, and maintenance requirements for continuous use.
Check electrical supply, mounting clearance, fasteners, airflow direction, guards, wiring, and access for service before installation.
Confirm the target equipment, operating point, ambient conditions, installation space, electrical supply, controls, protection, quantity, and required delivery date.
The product is classified as a axial fan. Use the full model code because nearby variants can differ in motor, mounting, and controls.
