Atlas Copco PF300-G-HW
Product Introduction:
The PF300-G-HW is a portable, electric-driven air compressor engineered for demanding construction and industrial applications requiring reliable compressed air in high-humidity environments. The “HW” designation indicates a high-humidity package equipped with enhanced moisture separation and aftercooling to deliver drier air output under tropical or coastal operating conditions.
Detailed content

Performance Parameters:
| Parameter | Value |
|---|---|
| FAD @ 100 PSI | 295 CFM (8.4 m³/min) |
| FAD @ 40 PSI | 450 CFM (12.7 m³/min) |
| Max Pressure | 175 PSI (12 bar) |
| Motor Power | 75 kW (100 HP) |
| Duty Cycle | 100% continuous |
Material Composition:
- Frame: High-strength structural steel with powder-coated finish
- Air End: Cast iron rotors with precision-ground lobes
- Tank: Carbon steel pressure vessel (ASME / PED certified)
- Cooling System: Aluminum plate-fin aftercooler
Structural Characteristics:
- Four-wheel trailer chassis with pneumatic tires
- Full roll cage for transport protection
- Anti-vibration mounts for motor and air end
- Accessible service panels on both sides
Working Principle:
Electric motor drives a two-stage rotary screw air end. Ambient air is drawn through an intake filter, compressed in the first stage, intercooled, then compressed in the second stage. The HW package routes compressed air through an enhanced aftercooler and cyclonic moisture separator before delivery to the tool connection.
Advantage Highlights:
- Zero exhaust emissions — compliant with indoor air quality regulations
- Superior moisture management in tropical climates
- Lower operating cost compared to diesel units (no fuel consumption)
- Reduced maintenance — no engine oil changes, filters, or coolant
Applicable Industries:
Construction, road building, quarry operations, painting and sandblasting, rental fleets, indoor tunnel work, marine and offshore support
Model Series: PF Series — Portable Free-Air Compressors (200–400 CFM range)
Installation Requirements:
- 400V 3-phase power supply with minimum 150A capacity
- Level ground surface for trailer deployment
- Minimum 3-meter clearance on all sides for airflow and service access
Usage Precautions:
- Do not operate in rain without additional canopy protection
- Verify power supply voltage matches unit rating before startup
- Perform daily drain of moisture separator in high-humidity operation
- Inspect air filter weekly; replace every 500 hours
