FAQ
Q1: What core performance features define the Rosenberg DKHR400-4SW.123.5FA centrifugal fan?
A1: The Rosenberg DKHR400-4SW.123.5FA is a 400 mm industrial centrifugal fan powered by 400 V three-phase voltage. It delivers a maximum static pressure of 470 Pa, with 540 W input power and 1340 RPM speed. This combination provides stable pressure output and reliable airflow, making it ideal for HVAC systems, ventilation units, and industrial air handling applications that require consistent medium-pressure performance under continuous operation.
Q2: Why is the Rosenberg DKHR400-4SW.123.5FA suitable for commercial and industrial ventilation systems?
A2: The Rosenberg DKHR400-4SW.123.5FA is designed for robust ventilation tasks with its 400 mm diameter and 400 V industrial power supply. It provides sufficient pressure to overcome duct resistance in medium‑scale ventilation systems while maintaining moderate power consumption. Its stable speed and durable structure ensure long service life, making it widely used in building ventilation, air conditioning units, and industrial process cooling systems.
Q3: How does the 1340 RPM speed influence the performance of the Rosenberg DKHR400-4SW.123.5FA?
A3: Operating at 1340 RPM, the Rosenberg DKHR400-4SW.123.5FA achieves a balanced combination of airflow, static pressure, and mechanical stability. This speed is optimized to generate 470 Pa static pressure efficiently while reducing vibration and wear on internal components. It supports smooth, quiet, and reliable operation for continuous duty, extending service life and lowering maintenance requirements in long‑term use.
Q4: What power supply requirements must be met for the Rosenberg DKHR400-4SW.123.5FA?
A4: The Rosenberg DKHR400-4SW.123.5FA requires a stable 400 V three‑phase industrial power supply to support its 540 W power consumption and maintain 1340 RPM speed. Voltage stability is critical to ensure consistent pressure output and prevent motor overload or performance degradation. A properly protected and regulated power source ensures safe operation and preserves the fan’s performance and lifespan.
Q5: What advantages does the 400 mm size offer in the Rosenberg DKHR400-4SW.123.5FA?
A5: The 400 mm frame size of the Rosenberg DKHR400-4SW.123.5FA makes it highly versatile for medium‑capacity ventilation and air handling systems. It fits standard HVAC and industrial units while providing enough volume capacity for effective air movement. Combined with 470 Pa pressure, it can handle moderate duct lengths and filtration systems, making it a cost‑effective and space‑efficient solution for many commercial and industrial cooling projects.
