Description
The ebmpapst R3G630-FB32-03 is a high-performance 400VAC EC Centrifugal Fan with dimensions of 660 x 660 x 405 mm, featuring a RadiPac backward-curved, single-intake impeller with a support bracket, specifically engineered for mission-critical cooling in Industrial Frequency Converters and large-scale air handling units. Driven by a 3-phase high-efficiency EC external rotor M3G150-IF motor with integrated electronics and maintenance-free ball bearings, this 28.6 kg unit operates on a 380 – 480 VAC supply delivering a Max. Power Consumption of 3700 W and a Max. Current Draw of 5.7 A at a rated speed of 1420 RPM. This High-performance unit achieves a Max. Air Flow of 7466.1 CFM (12685.0 m³/h / 211.42 m³/min) and a Max. Static Pressure of 72.50 mmH₂O (711.0 Pa / 2.85 inAq). Featuring intelligent speed regulation via 0-10V/PWM and RS-485 MODBUS-RTU (V6.3), integrated PI controller, and passive PFC, this 6-blade unit with PP plastic construction is optimized for industrial VFD systems requiring advanced motor protection and massive airflow in a black-painted rotor design at the end.
