A diesel
Mobile Air Compressor is a mobile air compression device powered by a diesel engine, which drives the compressor rotor (such as a screw type) through the diesel engine to compress air into high-pressure gas. The diesel engine drives the compressor main unit (such as a screw rotor), which sucks in, compresses, and stores external air into a storage tank, generating air pressure energy. Diesel mobile air compressors have strong mobility and are convenient for field operations (such as mines and construction sites). They are designed for towing or lifting. Widely used in mining, water conservancy engineering, transportation construction, shipbuilding, petrochemicals, power maintenance, and geological exploration (such as geophysical logging), providing gas source power support for pneumatic tools or equipment.
On construction sites, in repair shops, and even in remote outdoor areas, stable and reliable high-pressure air is an indispensable source of power. Portable air compressors and diesel-driven air compressors are efficient tools designed to meet these diverse needs. They combine powerful performance with excellent portability, making them ideal for professionals and DIY enthusiasts.

Who should prioritize this model?
If your work scenario meets the following requirements, this 20m³/18Bar
Mobile Diesel Air Compressor is the optimal solution: No stable power grid supply, or frequent changes in work location (e.g., field construction, multi-section infrastructure projects); Requires a high-pressure air source (≥15Bar) to drive heavy equipment, or multiple tools operating in parallel (e.g., large-diameter drilling, shotcreting); Harsh working environments (high temperature, high altitude, dust, vibration), requiring high equipment durability; Seeking "one-stop air supply," hoping to save the cost and hassle of machine room construction and long pipeline laying.
It's not just an air compressor, but also the "power core" for high-load field operations—breaking performance limits with high pressure and high flow, overcoming scenario limitations with free mobility, and ensuring continuous construction with heavy-duty durability, making air supply "stable, efficient, and worry-free" under complex working conditions.
In addition to 20 m3 18 bar portable diesel air compressor, we can also customize air compressor. We can do it at ZAKF.
It is a self-contained air compressor unit powered by a diesel engine, mounted on a wheeled trailer or skid chassis so it can be towed or lifted to any job site. Inside, an oil-lubricated rotary screw air end delivers continuous, high-volume compressed air — no external power supply is needed, making it the standard choice for remote and off-grid operations.
Q2. Which applications is it used for? +
Typical duties include mine and quarry drilling, water well drilling, blast-hole drilling, pipeline and tank purging, shot blasting, sand blasting, tunnel construction, road maintenance and any field job where air tools or drill rigs run far from electricity.
Q3. Why choose diesel instead of an electric compressor? +
Diesel-powered units work anywhere — with no power grid, no generator hire, and no long cables. They are also preferred for drilling rigs that move frequently, because the compressor follows the rig as one self-contained package. If your site has stable power, an electric unit may be cheaper to run; we can advise based on your location.
Q4. What pressure and capacity ranges do you offer? +
Our mobile diesel screw compressors typically cover 8–35 bar operating pressure with capacities from about 5 to 40 m³/min, sized for single drill rigs up to large multi-rig operations. Tell us the drill or tool consumption and working altitude, and we will match the right model.
Q5. Is it fuel-efficient? +
Yes. The diesel engine is matched to the screw air end to run at its most efficient speed, with automatic load/unload or variable speed control that cuts fuel use when air demand drops. Typical consumption ranges roughly 10–60 L/h depending on model and load; we provide measured fuel curves for every unit.
Q6. How noisy is it? +
Sound-insulated canopy models run at approximately 70–80 dB(A) at 7 m, meeting common noise limits for urban and night work. Optional ultra-quiet packages are available where strict noise regulations apply.
Q7. How is it moved around? +
Standard models come on a towable trailer chassis with overrun brake, mudguard lights and towing hitch, ready for a pick-up or truck. Skid-mounted versions are available for container or flat-rack shipping and crane handling. Every unit has lifting points and is balanced for safe transport.
Q8. Can it work in harsh conditions — heat, cold, altitude? +
Yes. The units are engineered for ambient temperatures from about −20°C to +50°C with cold-start kits (glow plugs, battery heaters) and heavy-duty air filters for dusty sites. High-altitude derating is handled by correctly sizing the engine; we confirm your site elevation when recommending a model.
Q9. What maintenance does it require? +
Maintenance follows a simple schedule: engine oil, fuel filters and air filters as per engine manual, plus the Screw Compressor's oil filter, oil separator and oil change every 2,000–4,000 hours. Daily checks cover oil levels, coolant and fuel. A complete service kit and maintenance chart are supplied with every machine.
Q10. Does it have an automatic control system? +
Yes. The controller provides auto start/stop, load/unload regulation, pressure setting, and full safety protection — high temperature, low oil pressure, overcurrent and emergency stop. Optional remote monitoring lets you track operation, fuel level and alarms via cloud or mobile app.
Q11. Can it run continuously? +
Yes, these units are designed for continuous operation at rated load, with heavy-duty diesel engines built for long field shifts. The canopy and ventilation system keep engine and compressor temperatures stable even in hot climates.
Q12. Do you support customization and OEM/ODM? +
Yes. As the manufacturer, we customize pressure settings, engine brand and power, trailer type (towable/skid/container), canopy options, voltage for the auxiliary control system, color and branding, plus OEM/ODM packages with your logo and documentation.
