K3G146-AC15-01 ebmpapst 230VAC 146mm EC Centrifugal Fan

Description

The ebmpapst K3G146-AC15-01 is a high-efficiency EC centrifugal fan assembly powered by the M3G055-DF motor, designed for precision air handling in industrial and residential applications. Featuring a 146 mm impeller and a robust black PP plastic housing, this unit is engineered for optimized air displacement with a power consumption of only 60 W at a rated speed of 910 RPM. The advanced EC motor technology incorporates a comprehensive control interface, supporting 0-10 VDC or PWM speed inputs alongside a Tacho output and a 10 VDC supply for external sensors. To ensure quiet operation, the motor is vibration-damped on both sides within its specialized suspension system. Built for durability, it features galvanized rotor surfaces, premium ball bearings, and thermal overload protection, maintaining reliable S1 continuous operation across an ambient temperature range of -25 °C to 50 °C.
