Industrial Gold RS503H128

Industrial Gold RS503H128 is a 50 HP oil-flooded rotary screw air compressor delivering 185 SCFM on a 120-gallon integral tank, wired for 208-230V, rated for continuous-duty industrial service. The RS503H128 is a high-capacity screw unit for production facilities, auto body shops, and industrial plants requiring sustained multi-station airflow. Oil-flooded screw technology provides lower operating temperatures, quieter operation, and longer service intervals than piston compressors at comparable output. The 120-gallon integral tank provides reservoir capacity without requiring a separate storage vessel. Priced at approximately $28,339 through Industrial Gold authorized distributors. Operating PSI rating, weight, noise level (dB), and an OEM datasheet URL are not confirmed in available data; request the Industrial Gold RS503H128 spec sheet from an authorized distributor for full installation parameters.
