The Atlas Copco XAS 950 PD8 T4F is a single-stage, oil-injected, rotary screw type air compressor, powered by a liquid-cooled, six- cylinder turbocharged diesel engine.

The unit consists of an air end, diesel engine with exhaust treatment, cooling circuit, air/oil separation and control systems - all enclosed within a sound dampened steel enclosure.

A range of undercarriage formats, factory and locally installed options are available.

Special attention has been given to the overall product quality, user friendliness, ease of serviceability, and economical operation to ensure best in class cost of ownership.

Applications & Use Cases

Gunite / Shotcrete / Abrasive Blasting

XAS 900 application - gunite US

Shotcrete, gunite, or sprayed concrete becomes an easier task when the materials are pushed through a hose and pneumatically projected at high velocity onto a surface using our air compressors. Whether you're doing road work, building a pool or laying concrete, our range of compressors can get the job done. 

Horizontal Directional Drilling (HDD)

Drillair Y35 compressor application belgium

HDD is a trenchless technology that use surface-launched equipment to drill underground horizontally and install pipes, conduits, and cables. This process can be air-driven and are used in numerous industries, such as utilities and telecommunications, at sites in dense, urban areas and/or where traditional vertical excavations are too dangerous (e.g., under bodies of water). 

Compressors in the DrillAir line can power large-diameter and/or long-run HDD processes with high throughput. The power of these units maximizes the efficiency of drilling operations, lowering project overhead and decreasing downtime. 

  • Can be employed to install underground utilities
  • Allows operators to drill horizontally controlling the direction of drill
  • The compressor powers the hammer at the end of the drill and uses air to clear dirt and debris

Blast Hole Drilling

Yellow machinery is drilling holes on the top of rocky sea cliff during blasthole drilling operations. Earthmoving, excavations, digging on the rocky soils.

The DrillAir range provides one of the highest air volumes at one of the highest air pressures available in the portable compressor industry. This also makes these new compressors one of the most energy efficient by having a very low specific fuel consumption for the air delivered.

Dynamic Flow Boost ® increases flow from 34.8 to 39m³/min (650l/s) when flushing and during drill stem refill. It means faster flushing, faster stem refill and a shorter time to finish a well.

High penetration rate with 35 bar pressure and 34.8m³/min (580l/s) flow means more meters drilled every day.
