Description
The ebmpapst R3G190-RB01-08 is a high-performance 230VAC EC Centrifugal Fan featuring a RadiCal® backward-curved, single-intake impeller specifically engineered for mission-critical cooling in Industrial Frequency Converters and precision air handling units. Driven by a high-efficiency EC external rotor M3G055-BD motor with integrated electronics and maintenance-free ball bearings, this 0.94 kg unit operates on a 230 VAC supply (range 200 – 240 VAC) delivering a Max. Power Consumption of 38 W and a Max. Current Draw of 0.38 A at a rated speed of 2370 RPM. This High-performance unit achieves a Max. Air Flow of 332.5 CFM (565.0 m³/h / 9.42 m³/min) and a Max. Static Pressure of 30.59 mmH₂O (300.0 Pa / 1.20 inAq). Featuring intelligent speed regulation via 0-10V/PWM control input with SELV potential, Soft start, and Power limiter, this 7-blade unit with PP plastic construction is optimized for industrial VFD systems requiring advanced motor protection and efficient airflow in a thick-film passivated rotor design at the end.
