Description
The ebm-papst K3G630-AR02-01 (also known as K3G630AR0201) is an industrial high-efficiency RadiPac EC centrifugal fan module engineered with an unhoused backward-curved 7-blade aluminum impeller housed in a robust structural cube frame. Powered by an integrated M3G200-HF three-phase electronically commutated motor operating across 380 to 480 VAC at 50/60 Hz, this 630 mm (24.8 in) module delivers an exceptional airflow output up to 13,925 CFM (23,655 m³/h) and static pressure capabilities up to 4.62 in H₂O (1,150 Pa). Built with a die-cast aluminum electronics housing, high-performance ball bearings, and IP55 environmental ingress sealing, it provides intelligent thermal and locked-rotor protection via a unified terminal box interface.
