Blower C402 RD (24V DC) Gianneschi

The Gianneschi C402 RD is an ultra-compact centrifugal fan designed for ships operating on a 24V DC power supply. Specifically engineered to move targeted airflows (6-15 m³/min) through small-diameter ducts, it outperforms axial models in its ability to maintain a constant flow rate despite duct resistance. Its RD (Right-Hand Rotation) configuration makes it a standard and easy to integrate into ventilation systems for bilges and confined technical spaces.

Centrifugal Performance: Mastering Small Spaces

With a power consumption of 0.11 kW, the C402 RD offers a perfect balance between low energy consumption and aerodynamic efficiency. It is the essential tool for removing hot or stale air from areas where a conventional fan cannot overcome pressure drop (narrow ducts, bends, filters). Its robust design allows it to operate in any position, adapting to even the most complex mounting configurations behind bulkheads or under floorboards.

Airtight and Modular Installation

Despite its small size, Gianneschi has made no compromises on engineering: this blower offers the option of adding counter flanges for a direct and perfectly airtight connection to circular ventilation ducts. This airtight seal ensures that the full 15 m³/min airflow is delivered precisely where it is needed, without any pressure loss in the bilge.

Marine Reliability and 24V Safety

Designed for continuous operation, this blower handles clean or slightly dusty airflows at temperatures ranging from -20°C to +80°C. Its 24V DC motor is particularly reliable for pleasure craft and service vessels. For sensitive environments, such as battery vapor extraction, versions with spark-proof motors are available on request for total safety.
