ELGi S017180-460-125

ELGi S017180-460-125 is a 50 HP rotary screw air compressor delivering 248 SCFM, rated to 175 PSI maximum, simplex configuration at 2,447 lbs. This unit corresponds to the ELGi EG 37 base-mounted fixed-speed model with configurable pressure range (100-175 PSI). Priced at approximately USD 28088 (Compressed Air Advisors, May 2026). Data quality note: the MPN S017180-460-125 suggests 460V three-phase wiring, but the typed voltage field shows 115V — verify electrical requirements before ordering. The EG 37 product line targets heavy industrial facilities requiring continuous high-volume compressed air. Known gaps: PSI rating at rated SCFM, confirmed voltage, lubrication type (likely oil-injected per retailer), and OEM datasheet URL not confirmed.
