Description
The ebmpapst K3G225-RE07-03 (Ident No. M3G055-DF) is a high-performance 230VAC EC Centrifugal Fan with dimensions of 270 x 270 x 131 mm, featuring a RadiCal backward-curved impeller with housing specifically engineered for mission-critical cooling in Industrial Frequency Converters and high-precision HVAC systems. Driven by a high-efficiency EC external rotor motor with integrated electronics and maintenance-free ball bearings, this 2.5 kg unit operates on a 200 – 240 VAC supply delivering a Max. Power Consumption of 170 W and a Max. Current Draw of 1.4 A at a rated speed of 2860 RPM. This High-performance unit achieves a Max. Air Flow of 741.6 CFM (1260.0 m³/h / 21.00 m³/min) and a Max. Static Pressure of 61.18 mmH₂O (600.0 Pa / 2.41 inAq). Featuring intelligent speed regulation via 0-10V/PWM control input, Soft start, and Power limiter, this 7-blade unit with PA plastic construction is optimized for industrial VFD systems requiring advanced motor protection and massive airflow in a passivated thick-film rotor design at the end.
