What is an Air Compressor?
An air compressor is a mechanical device that converts power from an electric motor or diesel engine into potential energy stored as compressed air. By drawing in ambient air and reducing its volume through rotating screws or a piston mechanism, the compressor delivers a continuous, high-pressure air supply used to drive pneumatic tools, machinery, and industrial systems. In mining, construction, and drilling, compressed air is the primary power source for rock drills, DTH hammers, and pneumatic equipment where electricity is unavailable or unreliable.
Moderate Machine manufactures both screw-type and piston-type air compressors, in electric and diesel-driven configurations, to match a wide range of site conditions and airflow requirements.
Advantages of Our Air Compressors
High Energy Efficiency Air Compressor Design
Our VSD (Variable Speed Drive) electric screw air compressors automatically adjust motor speed to match real-time air demand, cutting energy waste compared with fixed-speed compressors while maintaining stable airflow output.
01
Rugged, Dustproof & Waterproof Air Compressor Housing
Our diesel screw air compressors are built with sealed, dustproof and waterproof enclosures that let the compressor withstand extreme temperatures, dust, and moisture found on mining and outdoor construction sites.
02
Flexible Mobile Air Compressor Configurations
Our air compressors are available in stationary, two-wheel, four-wheel trailer, and crawler-mounted configurations, so the unit can be relocated easily between job sites without extra lifting equipment.
03
Low-Maintenance Screw Air Compressor Components
Reinforced screw air-end components reduce wear, extending the air compressor's service intervals and keeping downtime low even under continuous heavy-duty operation.
04
05 Fully Customizable Air Compressor Specifications
Airflow, working pressure, voltage, engine brand (Cummins, Weichai, Yuchai, Xinchai), trailer type, and outlet fittings can all be configured to your project's exact air compressor requirements.

Types of Air Compressor We Manufacture
Electric Stationary Screw Air Compressor
Fixed-installation air compressors for factories and workshops requiring a continuous, stable compressed air supply with lower noise and energy-efficient VSD options.
Electric Mobile Screw Air Compressor
Trailer- or wheel-mounted electric screw air compressors for sites with access to power but needing flexible on-site relocation.
Diesel Screw Air Compressor
Self-powered, engine-driven air compressors for mining, drilling, and construction sites without grid electricity — available in stationary, two-wheel, four-wheel, and crawler configurations.
Piston Air Compressor
Reciprocating air compressors suited to intermittent, lower-volume compressed air needs such as small workshops, auto repair, and general maintenance tasks.
Applications of Air Compressor
Mining Operations
Our air compressors supply the continuous compressed air needed to power pneumatic drills, DTH hammers, and air hoists in harsh, dusty underground and open-pit conditions.
Construction Sites
Compressed air from our compressors drives jackhammers, compactors, and pneumatic tools where electrical power is limited or unavailable.
Water Well & Tunnel Drilling
Our diesel screw air compressors deliver the continuous high-pressure air required for DTH drilling rigs and rock drills.
Oil & Gas Exploration
Our air compressors provide breathing air, pneumatic tool power, and process-control air on offshore platforms and remote oilfields.
Industrial Manufacturing
Stationary electric air compressors drive pneumatic clamps, valves, and conveying systems on production lines.
Auto Repair & Workshops
Compact piston air compressors power tire inflation tools, spray guns, and air wrenches in garages and service centers.

How to Order Custom Air Compressors
Send your inquiry with required airflow, pressure, and application details.
01
Our engineers recommend a suitable air compressor model or propose a custom configuration.
02
Confirm specifications, engine/voltage options, and place a 30% deposit.
03
Production, factory testing, and quality inspection (about 20–30 days).
04
Balance payment, shipping documentation, and dispatch via sea, air, or rail.
05
A Brazilian customer operating in hot, humid coastal-to-Andean conditions needed one air compressor capable of powering 2–3 jack hammers simultaneously, with strong corrosion resistance for the climate. We supplied a 185CFM diesel screw air compressor fitted with an oil-water separator and a one-to-three air distribution manifold. The unit ran 500 hours without a high-temperature shutdown and delivered around 12% fuel savings versus the customer's previous compressor.
