The Ingersoll Rand compressor head specifically refers to the core compression assembly of screw air compressors manufactured by the Ingersoll Rand (IR) brand, also known as the main unit or 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) |
| CF75D8 | 61.3 | 6.16 | 15 | 415*251*210 | 57 |
| CF90D4 | 45 | 7.26 | 15 | 481*300*255 | 85 |
Features
As a leading global air compressor brand, Ingersoll Rand's air compressor heads are renowned for their superior engineering. Key features include:
1. High-Efficiency Profile Design
◦ The rotor tooth profile (profile) is a closely guarded secret among various companies. Ingersoll Rand's patented asymmetric rotor profile design optimizes leakage control during the compression process, improving volumetric efficiency and specific power, resulting in greater energy savings.
2. Superior Bearing System
◦ High-quality, large-size, heavy-duty bearings withstand high loads and high speeds, ensuring precise rotor clearances over time – the foundation for long-term, efficient operation.
3. Stringent Manufacturing Processes and Materials
◦ The rotors are typically constructed from high-strength, wear-resistant alloy steel and undergo precision CNC grinding and dynamic balancing to ensure extremely low noise and vibration.
◦ The housing design balances strength and heat dissipation. 4. Integrated Design
◦ As an original equipment core component, it is optimally matched with the Ingersoll Rand complete machine's control system, cooling system, and lubrication system (such as oil injection), ensuring the most stable performance.
Applications
Ingersoll Rand airheads are primarily used in its full range of screw air compressors, including:
• Stationary screw air compressors: From small and medium-sized oil-injected screw air compressors to large oil-free screw air compressors.
• Mobile screw air compressors: Diesel-driven air compressors used in construction, mining, and other fields.
