The Gianneschi C402 RD (Three-Phase) is a high-precision centrifugal fan designed for marine infrastructures requiring rigorous air management. Unlike axial fans, its centrifugal technology generates sufficient pressure to propel air through ventilation ducts, filters, or mist separators. Powered by 230/400V AC, it delivers a constant flow rate of 48/51 m³/min, ensuring maximum thermal efficiency for technical rooms and engine compartments.
Three-Phase Performance: Stability and Efficiency
With a power rating of 0.25 kW, the three-phase version of the C402 RD is the ideal solution for installations requiring uninterrupted operation. Its motor overcomes pressure losses (air resistance) created by complex ductwork without overheating. Its versatile design allows it to operate in any position, adapting to the most demanding mounting configurations, whether on the ceiling, wall, or pedestal.
Airtight Mounting and RD Orientation
The RD (Right Rotation) configuration simplifies integration into standard ventilation systems. To ensure lossless performance, Gianneschi offers optional counter flanges for a perfectly airtight connection to circular ventilation ducts. This airtight seal is crucial for delivering the full 51 m³/min airflow precisely where cooling is required.
Marine Robustness and Custom-Designed Safety
Designed to withstand corrosive marine environments, this fan operates in air temperatures ranging from -20°C to +80°C. Its reliability makes it a top choice for hot air extraction from engine rooms. For areas exposed to flammable gases or vapors, versions with spark-proof motors are available on request, offering total operational safety.
