FN045-4DD.4F.A7P1 1163571 is a 400 VAC axial fan for chillers, cold-chain equipment, industrial refrigeration. Its main supplied feature is bionic blade geometry developed for efficient, low-noise airflow. It also lists a 450 mm size specified in the upload data. Review performance curve for equipment design.
The ZIEHL-ABEGG FN045-4DD.4F.A7P1 1163571 is an AC axial fan developed for renewable-energy and power-conversion equipment. It gives equipment designers a defined airflow or control solution for managing heat under continuous operating conditions.
The 400 VAC rating should be matched to the equipment supply and the complete model suffix. Biomimetic impeller geometry inspired by owl-wing aerodynamics is optimized for high efficiency and low noise. Dynamic balancing and a compact air path support low vibration, energy-conscious operation and long service life.
Before volume ordering FN045-4DD.4F.A7P1 1163571, confirm the duty point in the finished enclosure and review connector or controller requirements. The result is a documented solution for engineering, procurement and maintenance.
Within photovoltaic, bioenergy and fuel-cell equipment, ZIEHL-ABEGG FN045-4DD.4F.A7P1 1163571 moves heat away from power-conversion assemblies exposed to changing generation loads. Stable ventilation supports predictable operation when ambient conditions and equipment demand vary.
This application gives designers a practical route to balance cooling demand, space and maintainability. ZIEHL-ABEGG FN045-4DD.4F.A7P1 1163571 addresses airflow needs in power transformers and electrical conversion equipment and helps dissipate losses produced during sustained loading.
For HVAC, outdoor air-conditioning and ventilation equipment, the FN045-4DD.4F.A7P1 1163571 AC axial fan supports ventilation duty where filters, coils and duct resistance affect airflow. Directed airflow is valuable when filters, coils or enclosure geometry add resistance to the cooling route.
Effective circulation helps the wider installation retain its intended operating temperature. FN045-4DD.4F.A7P1 1163571 supports chillers and heat-pump systems. In this duty, it draws heat through condenser or heat-exchange sections in chiller equipment.
The supplied files do not establish a universal 24/7 duty rating. Validate ambient conditions, duty cycle, protection, and maintenance requirements for continuous use.
The supplied application data covers chillers, cold-chain equipment, industrial refrigeration. Confirm the installation's airflow, pressure, space, and electrical requirements.
Match the complete model code, voltage, dimensions, mounting arrangement, airflow direction, performance point, and control interface to the equipment.
The upload row lists RoHS compliance, but no additional exact-model certification is confirmed in the supplied feature record.
Verify the listed size, mounting pattern, fan housing or nozzle arrangement, airflow direction, and service clearance against the equipment drawing.
The matched series information describes speed-control capability. Confirm the exact control method and required controller for this model before commissioning.
