In off-grid industrial fields such as open-pit mining, road construction, deep well drilling, and remote sandblasting, grid electricity is often unavailable or unreliable. Operations in these demanding locations require a compressed air source that is robust, autonomous, and built to withstand dust, high heat, and rough terrain. To meet these rigorous field challenges, OPPAIR has officially introduced its heavy-duty OPM-37-8 Diesel Mobile Screw Air Compressor, combining robust engine power, intelligent engineering, and field-tested durability.
▲ OPPAIR OPM-37-8 Diesel Mobile Screw Air Compressor: 37 kW (1600 RPM), 8 Bar (116 PSI), 4.5 m3/min (158 CFM) volumetric flow.
Core Engineering Features: Built to Perform in the Toughest Conditions
The OPPAIR OPM-37-8 is not an ordinary portable compressor; it is an industrial workhorse engineered from the chassis up for non-stop reliability under demanding ambient conditions. Key engineering highlights include:
- XICHAI 4-Cylinder Industrial Diesel Engine: Powered by a proven XICHAI 4-cylinder diesel unit operating at a fuel-efficient 1600 RPM. This low-speed, high-torque configuration ensures steady power delivery, extended engine lifespan, and superior cold-start capability even in rugged climates.
- High-Precision Screw Air End: Featuring large-diameter, high-efficiency twin-screw rotors machined to micrometer tolerances. The air end delivers a consistent volumetric output of 4.5 m3/min (158 CFM) with minimal vibration and high thermal efficiency.
- High-Flow Cooling Radiator: Specially designed with an enlarged heat dissipation area to cope with high ambient temperatures, intense solar radiation, and heavy airborne dust, preventing overheating during 24/7 continuous operation.
- 80L Heavy-Duty Fuel Tank: Equipped with an 80-liter corrosion-resistant fuel tank, allowing long continuous operating shifts without frequent refueling interruptions.
- Reinforced Tow Bar & High-Load Axle: The heavy-duty suspension, high-load carrying axle, and reinforced towing tongue ensure stable tracking when towed behind utility vehicles over uneven gravel and mountainous quarry tracks.
Smart Maintenance: 360-Degree Gull-Wing Open Canopy
Routine field maintenance must be quick and hassle-free. The OPM-37-8 features a 360-degree gull-wing open canopy. Operators can easily lift both side access doors to gain unobstructed, eye-level access to the engine oil filter, air intake filters, oil-gas separation system, radiator, and electrical control panel.
Additionally, the fully enclosed, powder-coated steel enclosure provides comprehensive acoustic dampening, keeping operating sound levels down to 75 ± 3 dB, which significantly improves operator comfort and reduces noise pollution on job sites.
Tailored for Tough Industrial Applications
Delivering a steady exhaust pressure of 8 Bar (116 PSI) and a flow rate of 4.5 m3/min, the OPM-37-8 is the ideal air power package for a wide range of mobile field tasks:
- Mining & Quarrying: Powers heavy pneumatic jackhammers, rock drills, and secondary breaking tools reliably on remote pit faces.
- Sandblasting & Surface Preparation: Supplies clean, stable, high-volume air for continuous sandblasting and rust removal on bridges, storage tanks, and structural steel.
- Road & Municipal Infrastructure: Drives pavement breakers, soil compactors, and utility boring equipment for highway and pipeline repairs.
- Water Well & Geotechnical Drilling: Supplies sufficient back-pressure and volumetric volume for medium-depth drill hole flushing and pneumatic drilling tools.
