ELGi S019294

ELGi S019294 is a 7.5 HP single-stage oil-lubricated rotary screw air compressor delivering 42.5 SCFM at 100 PSI, with a maximum pressure rating of 175 PSI, wired for 230V. The compact 1-gallon receiver tank makes this a base-mount or direct-mount unit intended for continuous-duty industrial service — a common ELGi configuration for floor-level plant air, pneumatic tool networks, and process equipment requiring steady SCFM output. Oil-lubricated screw technology runs quieter and cooler than piston compressors at comparable output, with lower maintenance intervals. Priced at approximately ,540 through industrial distributors. Weight, noise level (dB), and physical dimensions are not confirmed in available data; consult ELGi or an authorized distributor for the S019294 datasheet and full installation specifications.
