ActronAir Fan Blower 10x10 S 1HP ECM ELGEE H-Steel is the single-blower 10x10 ELGEE assembly for AIRES and Advance R32 indoor units where the housing configuration suits a single large-impeller layout rather than the twin-deck arrangement, providing 1HP ECM performance in a more compact assembly footprint for installations where twin-deck clearances are not available. The H-Steel W-PVC ELGEE construction provides the structural rigidity needed for the 10x10 impeller higher rotational inertia without the corrosion vulnerability of plain steel in humid indoor unit environments. Isolate power at mains before replacement -- live work on fan assemblies is dangerous and must only be performed by a qualified technician.
