R3G630-AB06-03 ebmpapst 400V 4.2A 630mm EC Centrifugal Fan

Description

The ebmpapst R3G630-AB06-03 is a high-performance 400 V industrial EC centrifugal fan with an impeller size of 630 mm, purpose-built to deliver elite-level thermal cooling in high-resistance airflow paths. This unit features a heavy-duty M3G150-IF brushless EC motor capable of sustaining a 2800 W power input to drive its specialized 6-blade backward-curved aluminum impeller at a consistent 1200 RPM. Engineered specifically for air displacement in large-scale air handling units and data center cooling systems, it utilizes a high-efficiency aerodynamic design to provide superior static pressure for central ventilation in mission-critical hardware. The mechanical design relies on precision maintenance-free ball bearings and a black-painted rotor to ensure reliable continuous operation across an ambient temperature range of -25 °C to 50 °C. Featuring a sophisticated electrical interface with 0-10 VDC/PWM control, integrated PID controller, and RS-485 ebmBUS for real-time speed monitoring and adjustment, this fan is a critical component for HVAC systems, clean room modules, and industrial heat exchangers where maximum efficiency and intelligent system feedback are mandatory.
