The Ingersoll Rand compressor screw air end specifically refers to the core compression assembly of screw air compressors manufactured by the Ingersoll Rand (IR) brand, also known as the air end.
It is essentially a pair of high-precision, intermeshing screw rotors (male and female) and the precision housing that houses them. Its function is to convert the mechanical energy of the motor into the pressure energy of the air through the rotation of the rotors. It is the "heart" of the air compressor and directly determines the air production efficiency, reliability, and lifespan of the compressor.
Technical Parameters
| Model | Power (kW) | Flow (m³/min) | Working pressure ( bar) | Dimensions(mm) | Weight (kg) |
| OS70R | 22 | 3.63 | 6~16 | 368*217*195 | 43 |
| OS110R | 13.8~139.3 | 2.8~14.5 | 6~16 | 550*364*302 | 150 |
Features
1. Energy-Efficient Rotor Profile Design Ingersoll Rand's patented asymmetric rotor tooth profile optimizes rotor meshing, effectively reducing internal leakage within the compression chamber and ensuring a more complete and faster compression process.
2. Superior and Reliable Bearing System Oversized, high-preload heavy-duty bearings are used. This design withstands extreme loads and temperature fluctuations, ensuring the rotors maintain extremely precise, minute clearances even at high speeds.Stable Operation: Effectively suppresses axial and radial movement of the rotors, resulting in smooth operation with minimal vibration and noise.
3. Advanced Manufacturing and Material Technology The rotors are constructed of high-strength, wear-resistant, and corrosion-resistant alloy steel. Machined using top-of-the-line precision CNC grinding machines, they ensure tooth profile accuracy and surface finish. The rotors undergo rigorous dynamic balancing (typically to G2.5 or higher), eliminating vibration risks at the source.
Applications
• Stationary screw air compressors
• Mobile screw air compressors
