Product Overview
The Ingersoll Rand R7.5i is engineered for manufacturing plant air supply, providing a stable 36.7 CFM at 125 psi. This 7.5 kW (10 HP) stationary unit utilizes an oil-injected rotary screw pump and a belt-drive direct coupling system to maintain performance without the pulse-vibrations of piston models. With a compact footprint of 960 x 690 x 1187 mm and a weight range of 280–345 kg, it fits into dedicated workshop corners while operating at a quiet 69 dB(A). The R7.5i is built for continuous industrial duty, featuring a Direct On Line (DOL) starter and a moisture separator to ensure air quality for pneumatic tools. Safety is managed through a smart controller that monitors low oil shutdown and overpressure protection, while the steel enclosure is powder-coated for rust resistance in industrial environments. This model operates on 3-phase power, making it suitable for facilities with 208V to 575V electrical grids.

Engineering Analysis
The technical core of the R7.5i lies in its transition from a 7.5 kW electrical input to a high-volume 1038 LPM output. By using an oil-injected pump, the system manages heat effectively during 24/7 operation, which is essential for a compressor rated for continuous industrial duty. The belt-drive direct coupling mechanism minimizes energy loss between the 10 HP motor and the air-end, allowing for a max pressure capability of up to 200 psi. Sound engineering is evident in the 69 dB(A) rating, facilitated by a shockproof body and anti-vibration mounts that isolate the rotary screw mechanism from the steel enclosure. The V-Shield technology specifically addresses common leak points in the piping system to ensure the 39.8–25.3 CFM range is not compromised by internal pressure drops. Electrical reliability is maintained via a TEFC motor and overload protection, ensuring the 60 Hz frequency cycles do not stress the internal components under heavy pneumatic load.
