FAQ
Q1: What core performance characteristics define the Rosenberg DKHR280-2SW.087.5FA centrifugal fan?
A1: The Rosenberg DKHR280-2SW.087.5FA is an industrial-grade centrifugal fan engineered for medium-to-heavy-duty ventilation tasks. It operates at a rated voltage of 400 V, with an input power of 680 W and a stable rotational speed of 2580 RPM. This parameter combination ensures robust torque output, making it capable of overcoming moderate airflow resistance to deliver reliable air movement for industrial cooling and ventilation systems.
Q2: What advantages does the 400 V rated voltage bring to the Rosenberg DKHR280-2SW.087.5FA centrifugal fan in industrial applications?
A2: The 400 V rating aligns with standard three-phase industrial power grids, eliminating the need for voltage conversion equipment and simplifying system integration. This compatibility ensures stable power input for continuous operation, while the three-phase power supply supports balanced load distribution across the motor windings, reducing heat generation and extending the fan’s service life in factory and heavy-industry settings.
Q3: How does the 680 W input power support the 2580 RPM operation of this centrifugal fan?
A3: The 680 W input power is calibrated to provide sufficient energy to drive the fan’s impeller at 2580 RPM, ensuring consistent torque even under load conditions such as long duct runs or air filtration systems. This power configuration balances performance and efficiency—avoiding energy waste from over-sizing while delivering the airflow and pressure needed for targeted industrial ventilation tasks, such as equipment cabinet cooling and workshop air exchange.
Q4: What key installation considerations should be noted for the Rosenberg DKHR280-2SW.087.5FA centrifugal fan?
A4: First, confirm the power supply is a stable 400 V three-phase grid to prevent motor damage from voltage mismatches or fluctuations. Ensure the mounting space accommodates the fan’s footprint, with unobstructed inlet and outlet areas to maximize airflow efficiency and minimize noise. Secure the fan to a rigid base to reduce vibration during 2580 RPM operation, which helps prevent mechanical wear and maintains long-term operational stability.
Q5: In what industrial scenarios does the Rosenberg DKHR280-2SW.087.5FA centrifugal fan deliver optimal performance?
A5: This fan excels in medium-scale industrial ventilation scenarios, including industrial control cabinet cooling, HVAC air handling units for manufacturing facilities, and localized exhaust systems for workshops. Its 2580 RPM speed and 680 W power output make it suitable for applications that require a balance of airflow volume and static pressure, while its 400 V compatibility ensures seamless integration into standard industrial power systems without additional modifications.
