It is a trailer- or skid-mounted Rotary Screw Air Compressor driven by an electric motor instead of a diesel engine. It delivers the same mobile, job-site-ready compressed air as a diesel unit but runs on grid power — with zero exhaust emissions, lower noise and significantly lower running cost, making it ideal for underground, indoor and emission-sensitive sites.
Typical duties include underground mining and tunneling, quarry and construction sites with grid access, shipyards, bridge and dam construction, indoor sandblasting and shotcreting, and any operation where diesel exhaust or noise is restricted — for example mines requiring battery/electric equipment.
Electric units eliminate fuel cost and exhaust fumes, run much quieter, require less maintenance (no engine oil, filters or glow plugs), and have lower total cost of ownership over time. They need a reliable power supply — typically 380V/660V or 1000V — so they are the right choice where electricity is available and emission rules are strict.
We supply motors for common mining and industrial supplies: 380V, 400V, 660V, 1000V and 1140V, 50/60Hz, with direct-on-line or soft-starter/star-delta starting depending on motor size and grid capacity. Confirm your site voltage and available transformer capacity and we will configure the correct drive package.
Our mobile electric screw units typically cover 7–17 bar with capacities from about 3.5 to 25 m³/min, matching drill rigs, shotcrete machines and pneumatic tools used in tunneling and mining. We size the unit to your tools' consumption and duty cycle.
Electric drive is inherently more efficient than diesel, and our units add high-efficiency IE3 motors and automatic load/unload or VSD control so power draw follows air demand. Compared with a diesel unit of the same size, energy cost per m³ of air is typically 40–60% lower, with near-zero idle losses.
Without a diesel engine, electric units are far quieter — typically 68–78 dB(A) at 7 m with the canopy, and optional ultra-quiet packages for noise-limited sites and night work. This improves working conditions in confined spaces like tunnels.
Standard models come on a towable trailer chassis with braking system and lights, or as a skid package for container transport and crane handling. The compact, balanced layout allows towing behind a pick-up or light truck and positioning inside tunnels or shafts.
Yes. Units are available with IP54/IP55 protection, dust-proof intake filters and cooling packages for hot or humid environments. For underground use, we confirm clearance, ventilation and power availability with you and configure the machine accordingly, including optional flameproof or EX-rated components where required.
Maintenance is simpler than diesel: no engine servicing. Routine work covers the Screw Compressor oil, oil filter, separator and air filter on the standard 2,000–4,000 hour schedule, plus checks of the motor, cooling fan and control system. A service kit and maintenance chart are included.
Yes. The PLC controller provides auto start/stop, pressure and flow control, load/unload regulation, soft start protection, and full safety alarms — high temperature, overcurrent, phase loss and emergency stop. Optional remote monitoring allows cloud-based operation tracking and diagnostics.
Yes, electric units are designed for continuous 24/7 duty at rated load, with adequate cooling even in hot conditions. The absence of an engine reduces vibration and wear, extending service intervals and overall life.
Yes. As the manufacturer, we customize voltage/frequency, pressure settings, trailer or skid type, canopy options, control and communication protocols, color and branding, plus OEM/ODM packages with your logo and documentation. We also supply complete packages with dryers and receivers.
Our factory is ISO 9001 certified, and the units carry CE certification; EX/flameproof versions are available for hazardous-area requirements. We provide full export documentation, including origin certificate, packing list and motor certification.
Standard models ship within 20–30 days after order confirmation; customized or EX versions take 35–60 days. Units are shipped on flat racks or in containers with export-grade lashing and weather protection, ready for sea freight worldwide.
We offer a 12–24 month warranty, 24/7 remote technical support with video guidance, installation and commissioning assistance, operator training, and long-term spare parts supply — most parts dispatched within 3–7 days to keep your fleet running.
