ELGi S017182-460-175 is a 50 HP single-stage oil-free rotary screw air compressor from the ELGi S-Series delivering 248 SCFM at up to 175 PSI, weighing 2,447 lbs. The oil-free design eliminates oil contamination risk in the compressed air stream — required for food processing, pharmaceutical manufacturing, electronics production, and breathing-air applications where Class 0 air quality is needed. Single-stage oil-free compression delivers Class 0 air quality without the oil-carryover risk of lubricated designs. Three-phase power supply required. Priced at $28,088. Known gaps: PSI rating at which 248 SCFM is measured, voltage phase/frequency spec needs clarification (catalog shows 115V which appears inconsistent with 50 HP three-phase unit), inlet/outlet connection sizes, noise level (dBA), and warranty terms not available in current catalog record.
