Compressed air is the lifeblood of countless industrial and construction operations. Down-the-hole drills need it to fire. Sandblasting rigs need it to propel abrasive. Pneumatic tools need it to operate. Without a reliable air source, the job stops. But not all compressors are built for the field. Stationary units anchor you to one location. Piston units overheat under continuous load. What you need is a small screw air compressor that moves with the job and runs all day without stopping.
The YG series portable screw air compressor delivers exactly that. It combines a high-efficiency screw air end with a 162kW Yuchai diesel engine—all mounted on a rugged mobile chassis. Five models cover free air delivery from 18 to 36 m³/min and rated pressures from 18 to 30 bar.

5 Advantages of Small Screw Air Compressor
- Space-saving integrated structure: The small rotary air compressor integrates the motor, screw air end, control system and filtration components into a single compact frame, requiring far less installation space than split-system compressors. It fits easily into corner spaces of workshops and small production areas without disrupting existing workflow layouts.
- Stable continuous output: Screw compression technology delivers non-pulsating airflow with consistent pressure, which prevents pressure fluctuations that can disrupt precision pneumatic tools and production processes. It runs continuously for full work shifts without the overheating issues common with small piston compressors.
- Low vibration and noise: The intermeshing screw rotors operate with smooth, balanced motion, producing far less vibration and noise than reciprocating piston units. This makes it suitable for use inside shared workspaces without causing excessive noise disturbance to workers.
- Flexible configuration options: Buyers can choose between electric and diesel power versions, as well as stationary base and wheeled mobile designs, to match the specific needs of their working environment.
- Rental and resale value. Portable compressors are in constant demand for rental fleets. Their mobility and versatility make them easier to rent, sell, or redeploy when project requirements change.
How to Choose the Right Small Screw Air Compressor?
Choosing the right small screw air compressor starts with understanding your application requirements.
- Air pressure requirement (bar). Most construction tools require 7-10 bar. DTH drilling requires 18-30 bar. The YG series delivers 18-30 bar across five models. Know your tool’s pressure requirement before selecting a model.
- Air volume requirement (m³/min). This is the volume of air your operation consumes. DTH hammers have specific flow requirements based on hammer size and hole diameter. The YG series delivers 18-36 m³/min. Larger hammers and deeper holes require more airflow.
- Power source. The YG mobile screw compressor uses diesel engines for independent operation. If you have reliable grid power at your job site, an electric motor may be suitable. For mobile applications and remote sites, diesel is the practical choice.
- Mobility requirement. The YG series is designed for mobility. For sites that require frequent relocation, the portable configuration is essential. For permanent installations, a fixed base may be sufficient.
- Single-stage or two-stage. Single-stage delivers up to 18 bar with simpler construction. A two-stage delivers up to 30 bar with better efficiency. Choose based on your pressure requirements.
Single-Stage vs. Two-Stage: Which Air End Fits Your Job
The YG series portable screw air compressor offers both single-stage and two-stage air end configurations. The choice depends on the pressure requirements of your application.
Single-stage compression (S60T) compresses air in one step, delivering up to 18 bar at 18 m³/min. Single-stage units are simpler, lighter, and have fewer components, making them more affordable and easier to maintain. For applications requiring up to 18 bar—such as general construction, light drilling, and sandblasting—the S60T delivers the pressure you need without the complexity of a two-stage system.
Two-stage compression (S85D/T through S125D) compresses air in two steps, with intercooling between stages. This design delivers higher pressure—up to 30 bar—with better energy efficiency. Two-stage systems can save 12-15% in fuel consumption compared to single-stage units delivering the same air volume at higher pressures. The two-stage design also runs cooler and provides a longer service life due to reduced thermal stress.
For high-pressure applications like deep-water well drilling and hard rock mining, the two-stage models are the preferred choice.
