Description
ebm-papst K3G560-PC04-01 (also known as K3G560PC0401) is an industrial high-efficiency RadiPac backward-curved EC centrifugal fan module engineered with an integrated support bracket and precision aerodynamically shaped inlet nozzle. Driven by an advanced 3-phase M3G150-NA permanent-magnet brushless EC motor, the 560 mm (22.05 in) 5-blade aluminum impeller achieves up to 12,515 CFM (21,265 m³/h) of airflow and static pressure capabilities reaching 5.22 in H₂O (1,300 Pa). The unit integrates active power electronics in a rugged die-cast aluminum housing offering continuous 5,000 W power management across wide 380–480 VAC 50/60 Hz industrial grids. Built for mission-critical air handling, it features an IP55 sealed enclosure, integrated RS-485 MODBUS RTU digital communication, configurable 0–10 V/PWM control interfaces, and dual ball bearings for durable S1 continuous duty.

Applications
ebm-papst K3G560-PC04-01 is widely deployed in commercial air handling units (AHUs), modular rooftop cooling systems, and large-scale data center computer room air handler (CRAH) plenums. Its robust structural module and aerodynamically optimized nozzle make it an ideal choice for cleanroom recirculation filtration banks, industrial process drying systems, and building ventilation retrofits. Engineering teams specify this RadiPac assembly across critical healthcare air handlers, paint booth exhausts, and institutional HVAC plant rooms requiring high static pressure capability and intelligent networked airflow monitoring.
