A screw air compressor provides continuous compressed air for drilling rigs, pneumatic tools, and industrial machinery. Diesel-powered models suit remote mining and construction sites without reliable grid electricity. Choosing the right model requires matching airflow and working pressure to equipment demand, drilling conditions, and daily operating hours.
Screw Air Compressor Parameters
| Model | Rated FAD | Rated Pressure | Engine | Air end | Weight |
| S60T | 18m³/min | 18bar | 162KW YUCHAI | Single Stage | 3000KG |
| S85D/T | 24m³/min | 22bar | 162KW YUCHAI | Two Stage | 3560KG |
| S95CD/T | 29m³/min | 24bar | 162KW YUCHAI | Two Stage | 4700KG |
| S100D/T | 31m³/min | 25bar | 162KW YUCHAI | Two Stage | 5600KG |
| S125D | 36m³/min | 30bar | 162KW YUCHAI | Two Stage | 5600KG |
Screw Air Compressor Selection for Drilling Equipment
Selecting a screw air compressor for drilling rigs starts with airflow and pressure requirements. Several factors affect the final model:
- Air consumption: Match compressor output to the drilling rig manufacturer’s specifications.
- Hole diameter and depth: Larger or deeper boreholes may require different drilling tools and operating conditions.
- Pipeline losses: Long hoses and pipe connections reduce pressure at the drill.
- Daily workload: Extended operating hours increase the importance of suitable capacity, cooling, and routine maintenance.
- Site mobility: A diesel screw air compressor suits remote projects without fixed electrical power.
For higher-pressure drilling, a high pressure screw air compressor may be necessary. YG’s listed S85D/T, S95CD/T, S100D/T, and S125D models use two-stage compression, with rated pressures ranging from 22 to 30 bar. Select the model according to the required airflow and pressure, not engine power alone.
Main Applications of Screw Air Compressors
Mine Pneumatic Drilling Equipment
Mine pneumatic drilling equipment uses compressed air to operate pneumatic drills in mines, quarries, and blast-hole projects. A mobile diesel screw air compressor allows crews to work away from permanent power infrastructure.
Industrial Pneumatic Sandblasting Equipment
Industrial pneumatic sandblasting equipment propels abrasive material onto steel, concrete, and other surfaces. Common applications include rust removal, coating removal, and steel surface preparation.
Food and Pharmaceutical Industry
The food and pharmaceutical industry uses compressed air in selected production, processing, and packaging operations. An oil-free screw air compressor may suit processes where oil contamination must be controlled.
The complete air system may require:
- Air dryers to control moisture
- Filters to remove specified contaminants
- Air-quality monitoring to meet process requirements
Oil-free compression alone does not guarantee that compressed air meets every production purity standard.
Starting of Large Marine Diesel Engines
Starting of Large Marine Diesel Engines requires a dedicated compressed-air system to turn the engine during startup. Equipment selection focuses on:
- Required starting pressure
- Air receiver capacity
- Compressor capacity and recovery time
- Engine manufacturer specifications
A drilling compressor is not automatically suitable for marine engine starting. System design must meet the engine’s requirements.
High-Pressure Air Blasting in Coal Mining
High Pressure Air Blasting Coal Mining uses specialized high-pressure air equipment for particular mining operations. Selection requires attention to:
- Required operating pressure
- Compressor and connected equipment ratings
- Pressure-control arrangements
- Approved operating procedures and site regulations
Standard drilling compressors should not be used for this application without confirming system compatibility.
Four Screw Air Compressors for Quarry Drilling in Uruguay
A quarry drilling project in Maldonado, southeastern Uruguay, provides an example of how contractors may plan compressed-air supply across multiple work areas. For this project, the contractor selects four YG S85D/T diesel screw air compressors for four drilling rigs.
Planned project details
Location: Maldonado, Uruguay
Equipment: Four YG S85D/T screw air compressors
Drilling rigs: Four YG-100DTH pneumatic drilling rigs
Borehole diameter: Approximately 90–115 mm
Drilling depth: Approximately 18–25 m
Daily operation: Around 8–10 hours
Why use four compressors?
- Dedicated air supply: Each rig receives its own compressor.
- Parallel operations: Four rigs can work in separate positions without sharing one compressor.
- Less equipment relocation: Crews do not need to move one air source repeatedly between drilling areas.
- Maintenance planning: Service can be scheduled by unit, subject to the project’s available backup capacity.
S85D/T specifications
| Parameter | Specification |
| Rated FAD | 24 m³/min |
| Rated pressure | 22 bar |
| Engine | 162 kW YUCHAI |
| Air end | Two Stage |
| Weight | 3,560 kg |
Before final selection, compare compressor output with each rig’s actual air consumption and working pressure. Borehole dimensions alone do not establish whether a compressor is suitable. Fuel supply, transport access, and maintenance arrangements also need to be included in the site plan.

For drilling contractors, choosing an air compressor involves more than comparing rated pressure. The drilling method, air consumption, operating hours, site access, and local maintenance conditions all affect the final configuration. YG can use these details to recommend a suitable compressor and coordinate the related drilling equipment.
FAQ
How do I choose a screw air compressor for drilling?
Check the drilling rig’s required airflow and working pressure. Also consider drilling depth, tool specifications, pipeline losses, and the number of rigs operating at once.
Is a diesel screw air compressor suitable for remote sites?
Yes. Diesel-powered models operate without a fixed electrical connection. Plan for fuel supply, transportation, routine servicing, and spare parts.
What is the difference between single-stage and two-stage compression?
Single-stage compression raises air pressure in one main stage. Two-stage compression raises pressure across two stages and is commonly used in higher-pressure models. Compare rated airflow and pressure when choosing equipment.
Can a screw air compressor run sandblasting equipment?
Yes, if airflow and working pressure meet the blasting system’s requirements. Nozzle size and the number of active blast guns determine total air demand.
