Product Overview
The Ingersoll Rand R5.5i-A125/80 integrates a 5.5 kW oil-injected rotary screw pump onto a 302.83 L horizontal tank to meet demanding workshop compressed air needs. Delivering a steady 27.5 cfm (0.78 m³/min), this model eliminates the downtime associated with intermittent duty cycles found in smaller piston units. Its 345 kg stationary frame utilizes anti-vibration mounts and noise insulation to achieve a 69 dB(A) sound level, which is significantly quieter than open-frame alternatives. The system is managed by a smart controller and digital display, ensuring the 7.5 HP motor operates within optimal thermal and pressure parameters. Designed for 208-575V 3-phase power, it provides the 8.6 bar pressure required for high-demand pneumatic equipment and spray guns. The powder-coated steel enclosure protects internal components like the moisture separator and thermal protection circuits, while the 3/4 inch NPT outlet ensures compatibility with standard industrial piping layouts.

Engineering Analysis
The R5.5i-A125/80 utilizes an oil-injected rotary screw design where the 5.5 kW motor drives the pump at 3475 rpm to generate 780 LPM of airflow. This direct or belt-driven configuration is specifically optimized for 100% duty cycles, meaning the 7.5 HP motor does not require rest periods during a full 60 Hz operational shift. The 8.6 bar (125 psi) max pressure is regulated via an automatic cut-off and pressure switch, preventing overpressure while the 302.83 L tank acts as a buffer to stabilize air delivery for fluctuating demands. Heat management is handled by an air-cooled system and thermal protection, which is critical for maintaining the viscosity of the oil-injected lubrication. By housing these components in a noise-insulated body, Ingersoll Rand reduced the acoustic output to 69 dBA, which mitigates the need for a dedicated remote compressor room. The inclusion of a moisture separator directly after the pump ensures that the 27.5 cfm output is conditioned for pneumatic tools before it enters the horizontal receiver.
