25 m3/min 882CFM 25 bar portable diesel air compressor

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Our factory is ISO 9001 certified; units carry CE certification, and engine emissions comply with applicable standards for your destination market (e.g. EPA/CARB or EU Stage versions available). We prepare all export documentation, including origin certificate and packing list.

Standard models ship within 20–35 days after order confirmation; customized units take 35–55 days. Mobile compressors are shipped on flat racks or in containers with full export-grade lashing and protection, ready for sea freight to any port.

We stock engine and compressor wearing parts — filters, separator elements, belts, hoses and control components — and guarantee supply for over 10 years, with most parts dispatched within 3–7 days to support your fleet anywhere in the world.

We offer a 12–24 month warranty covering the compressor unit and drive train, 24/7 remote technical support with video guidance, operator and maintenance training, and a worldwide distributor network for on-site service where available.
