Material Composition:
- Chassis Frame: High-strength structural steel S355 grade, hot-dip galvanized
- Fuel Tank: Carbon steel with internal epoxy coating
- Compressor Housing: Cast aluminum alloy
- Air End Rotors: Chrome-plated steel rotors with ATLAS Copco Sigma Profile
- Cooling Radiator: Aluminum bar-and-plate heat exchanger
Structural Features:
- Single-axle towable chassis with hydraulic jack legs
- Enclosed canopy with sound-dampening insulation
- Forklift pockets on all four sides for crane/forklift handling
- Anti-vibration mounts under engine and compressor
- Heavy-duty drawbar with D40 or 50mm towing eye
Working Principle: Diesel engine drives the rotary screw airend directly via flexible coupling. Ambient air is drawn through intake filters, compressed in the intermeshing male/female rotor set, cooled via aftercooler, and delivered as pressurized air. The PB (Power Booster) variant features an over-speed capable airend and enhanced cooling for sustained maximum output.
Key Advantages:
- Highest output in PF series at 40 m³/min
- Power Booster configuration for continuous full-load operation
- HW-rated for high-altitude performance without derating
- 800L fuel tank enables extended autonomous operation
Applicable Industries: Large-scale mining, quarrying, tunnelling, heavy civil construction, sandblasting operations
Installation Requirements:
- Flat, level ground with load-bearing capacity ≥ 15 tonnes/m²
- Minimum 3m clearance on all sides for airflow and maintenance access
- 400V 3-phase electrical connection required for control panel (optional auto-start)
Usage Precautions:
- Engine warm-up required for minimum 3 minutes before full load
- Oil change interval: every 500 hours or 6 months (whichever comes first)
- Air filter replacement: every 250 hours
- Do not operate in enclosed spaces without exhaust extraction
