Product Overview
The Ingersoll Rand R5.5I-A135-TAS/80 is engineered to provide a consistent 24.3 cfm at 135 psi (9.3 bar) for manufacturing plants and industrial workshops. This 5.6 kW (7.5 HP) system replaces intermittent-duty piston compressors with a 100% duty cycle rotary screw pump, ensuring that pneumatic tool operations never face pressure drops. The unit is mounted on a 302.83 L horizontal tank, providing a stable foundation and air buffer for high-demand spray guns or air lines. Noise levels are kept to a managed 69 dB(A), allowing the 483.75 kg stationary machine to be placed closer to the point of use. Its integrated dryer system removes moisture using R-134a refrigerant, protecting downstream equipment from corrosion. Electrical requirements are specific to three-phase 208-230V or 460V configurations at 60 Hz, ensuring the TEFC motor maintains efficiency across 5.6 kW power consumption levels.

Engineering Analysis
The technical core of the R5.5I-A135-TAS/80 lies in its oil-injected rotary screw design, which manages heat more effectively than reciprocating models to sustain a 24.3 CFM airflow indefinitely. The 5.6 kW motor is a Totally Enclosed Fan Cooled (TEFC) induction type, which operates at speeds up to 3,550 rpm to drive the direct or belt-dependent pump configuration. By utilizing a 302.83 L tank, the system reduces motor cycling frequency, extending the life of the Direct On Line (DOL) starter and the pressure switch. The smart controller regulates the auto-cutoff and overpressure protection to maintain the 9.3 bar maximum pressure safely. Structural integrity is maintained by a 483.75 kg steel enclosure that incorporates noise insulation and anti-vibration mounts, specifically tuned to counteract the 60 Hz frequency vibrations. This model integrates a 3/4 inch NPT air outlet directly into the moisture separator, ensuring that the 690 LPM of air delivered is free of liquid contaminants.
