Tunnel excavation, mining, and large-scale construction projects face unique air supply challenges: unstable pressure (causing tool failure), poor durability (due to dust/moisture), and insufficient air volume (delaying progress). Our Stationary Screw Compressor2 is engineered to overcome these pain points with tunnel-specific fixed structures, high-torque motors, and dust-proof designs. It delivers continuous, stable high-pressure air to power jackhammers, rock drills, and concrete sprayers—ensuring uninterrupted operation in harsh, confined environments.

Tunnel-optimized Fixed Structure: Thickened steel base with anti-slip anchor bolts—resists vibration from nearby drilling and keeps the unit stable on uneven tunnel floors.
Dual-Tank Design (SUPL30-8/SUPL40-8): Two integrated air tanks (total 300L) ensure steady pressure output, avoiding pressure drops that cause rock drill stalling.
Harsh Environment Resistance: IP54-rated motor and sealed electrical cabinet—prevent dust, water spray, and humidity from damaging internal components; service life extended by 30% in dusty mines.
Tunnel Excavation: SUPL175-13 model delivers 13bar high pressure to drive heavy-duty concrete sprayers, with DN65 large-diameter air outlet reducing airflow loss by 12%.
Underground Mining: Dust-proof casing and moisture separator prevent coal dust and underground water from entering the airend, ensuring reliable operation in 90% humidity environments.
Large Construction Sites: SUPL30-8’s four-wheel design (with locking brakes) allows flexible positioning near workstations, while dual tanks provide enough air for 2-3 jackhammers to operate simultaneously.
Screw Airend: Adopts 5:6 rotor profile with precision grinding (clearance ≤0.03mm); high-quality cast iron material resists wear, ensuring 8,000 hours of maintenance-free operation.
Cooling System: Large-area aluminum fin cooler with forced air circulation—effectively dissipates heat even in high-temperature tunnels (up to 45℃), avoiding overheating shutdowns.
Safety Protection: Equipped with over-pressure (15bar) and over-temperature (110℃) automatic shutdown functions; oil level monitoring prevents dry running, protecting the motor from burnout.
Customization: Offers anti-corrosion coating for marine tunnels and low-temperature adaptation (-10℃ startup) for alpine mining projects.
On-Site Service: Dispatches professional technicians to tunnel/mining sites within 48 hours for maintenance or repairs—no need to move the heavy unit (up to 2300Kg).
Warranty: 3-year warranty for the screw airend (critical for harsh environments), 1-year warranty for electrical components, and free annual safety inspections.
Training: Provides specialized training for on-site teams on dust-proof maintenance and emergency troubleshooting in confined spaces.
