Atlas Copco PF3109-G-HW
Product Series: PF3109 Series — 31 m³/min Generation 9 with Generator
Product Introduction: The PF3109-G-HW is a 31 m³/min portable compressor with integrated generator, built on the Generation 9 platform. It bridges the gap between the 30 m³/min and 40 m³/min classes, offering 3% more air than the standard PF3000 series while maintaining a compact footprint. The “G” configuration includes a generator. The “HW” rating supports high-altitude deployment.

Material Composition:
- Chassis: S355 structural steel, powder-coated
- Generator: IP23-rated brushless alternator
- Airend: GA 31 with 5:6 rotor profile, case-hardened steel
- Canopy: Galvanized steel with 40mm acoustic insulation
Structural Features:
- Single-axle trailer with hydraulic jacks
- Integrated generator compartment with separate access door
- Forklift pockets (4 points)
- Towbar with 50mm pintle hitch and breakaway cable provision
Working Principle: Deutz TCD 2013 L04 4V engine drives the GA 31 VSD+ airend and the 200 kVA generator simultaneously. The VSD+ system modulates airend speed to maintain constant discharge pressure, reducing fuel consumption by up to 30% at partial loads. Oil-injected compression provides internal sealing and cooling.
Key Advantages:
- 31 m³/min output fills the gap between 30 and 40 m³/min classes
- VSD+ technology on Generation 9 platform
- 200 kVA generator powers medium-scale site operations
- HW-rated for high-altitude use
Applicable Industries: Medium-scale mining, road construction, water well drilling, rental fleets, event power
Installation Requirements:
- Ground bearing capacity ≥ 12 tonnes/m²
- 3m clearance on generator side
- 400V 3-phase connection for control panel
Usage Precautions:
- VSD+ system requires stable voltage — use voltage stabilizer if grid quality is poor
- Check generator brush wear at 4,000-hour service
- Fuel filter change every 250 hours
- Do not operate with canopy doors closed in temperatures above 40°C
