High Pressure and High Airflow
The X-AIR⁺ 777-22 is designed for jobs where standard low-pressure compressors may not provide the pressure required by the equipment or process.
Its published operating range combines:
- 13–22 bar working pressure for demanding compressed-air applications.
- 19.4–21.6 m³/min airflow, depending on the specified operating point.
- 214 kW engine power to support high-capacity compressor operation.
When selecting a compressor, it is important to match both working pressure and free air delivery to the equipment’s requirements. Maximum airflow should not be assumed to be available at every pressure setting.
Two-Stage Compression Technology
The X-AIR⁺ 777-22 uses a two-stage compression configuration. In a two-stage system, air is compressed through two successive stages rather than a single compression stage.
This configuration is suitable for applications that require higher discharge pressure while maintaining substantial airflow. The compressor system and engine are engineered to operate together to meet the demands of continuous field work.
For operators, selecting the appropriate pressure and airflow combination helps ensure that the compressor matches the process rather than operating outside its intended range.
Cummins Diesel Power
The X-AIR⁺ 777-22 is powered by a Cummins diesel engine with a published rated output of 214 kW.
Diesel-powered operation allows the compressor to work at remote sites where a suitable electrical supply may not be available. This makes the machine useful for mobile operations, temporary installations and industrial projects that require a self-contained compressed-air source.
The precise engine model, emission standard and engine configuration should be confirmed against the machine’s identification plate and serial-number documentation.
Key Features and Benefits
High-Pressure Performance
A working pressure range of 13–22 bar supports applications that require more pressure than conventional construction air compressors typically provide.
Substantial Air Delivery
The published airflow range of 19.4–21.6 m³/min provides a high-capacity air supply for demanding pneumatic equipment and industrial processes.
Diesel-Powered Mobility
The integrated diesel drive allows operation at remote job sites without relying on an external electrical power source.
Designed for Demanding Work
The X-AIR⁺ platform is intended for field use across construction, mining and other heavy-duty applications. Correct operation and scheduled servicing help maintain long-term reliability.
Application Flexibility
The broad working-pressure range allows the machine to be considered for different jobs, provided the selected operating point meets the actual pressure and airflow requirements.
Typical Applications
The Atlas Copco X-AIR⁺ 777-22 can be considered for applications such as:
- Abrasive blasting and surface preparation
- Mining and quarry operations
- Construction and infrastructure projects
- Industrial maintenance
- High-pressure pneumatic equipment
- Selected drilling applications
- Compressed-air supply for demanding field operations
The suitability of the compressor depends on the application’s required pressure, air consumption, duty cycle and air-quality requirements.
FAQ
Before choosing the X-AIR⁺ 777-22 for a project, review these requirements:
-
Working pressure: Confirm the pressure needed at the point of use.
-
Airflow demand: Calculate the total air consumption of all equipment operating simultaneously.
-
Operating conditions: Account for ambient temperature, altitude and duty cycle.
-
Air quality: Determine whether aftercooling, moisture separation or filtration is required.
-
Transport and installation: Check the applicable chassis or mounting configuration.
-
Maintenance support: Confirm the availability of the correct service parts and technical documentation.
Atlas Copco China’s published specifications list a working-pressure range of 13–22 bar, approximately 189–319 psi.
Routine maintenance is essential to protect the compressor element, diesel engine and air-treatment components.
Important service areas include:
-
Compressor oil and oil filters
-
Air intake filters
-
Fuel filters and fuel system
-
Engine oil and coolant
-
Air/oil separation components
-
Cooling system
-
Hoses, fittings and air outlets
-
Pressure-control and safety systems
-
Electrical and monitoring components
Service intervals and replacement-part requirements should follow the maintenance documentation for the specific machine.
When purchasing spare parts, provide the full model designation and serial number. This helps identify the correct components for the particular production version.
The published free air delivery range is 21.6–19.4 m³/min, equivalent to approximately 763–685 cfm.
The published product specifications identify Cummins as the engine manufacturer and list a rated engine power of 214 kW. Confirm the exact engine model using the machine’s nameplate or serial-number documentation.
It can be considered for abrasive blasting where the required pressure and airflow fall within the machine’s operating capabilities. Final selection should account for nozzle size, blast pressure, hose configuration and the number of operators.
