Product Name: Atlas Copco PF4002-C-HU Oil-Free Piston Compressor

Product Overview:
Compact portable oil-free compressor. “4002” = 4.0 m³/min FAD, 2-stage. “C” = compressor element, “HU” = high-pressure, air-cooled (U variant cooling).

Detailed content

Technical Specifications:

  • FAD: 4.0 m³/min (141 CFM)
  • Max Working Pressure: 16 bar (232 psi) / 25 bar (363 psi) — option dependent
  • Motor Power: 30 kW (40 HP) electric or diesel
  • Cooling: Air-cooled (HU = air-cooled high-pressure)
  • Sound Level: 82 dB(A)
  • Weight: ~1,200 kg (electric) / ~1,450 kg (diesel)
  • Dimensions: ~2,000 × 900 × 1,300 mm

Material Composition:

  • Cylinders: Cast iron, chrome-plated
  • Piston rings: PTFE-coated carbon
  • Frame: Powder-coated steel
  • Aftercooler: Aluminum fin-cooled

Structural Features:

  • Two-stage oil-free compression
  • Compact skid design
  • Integrated air receiver (optional)
  • Forklift pockets standard

Working Principle:
Two-stage piston compression. Air is compressed in the first stage, cooled by the air-cooled aftercooler, then compressed in the second stage to reach up to 25 bar. Oil-free design via PTFE piston rings.

Key Advantages:

  • 25 bar capability — highest pressure in this list
  • Extremely compact for 4 m³/min output
  • Air-cooled — zero water requirement
  • Low weight enables manual repositioning

Applicable Industries:
Small paint shops, tire inflation, laser cutting, CNC spindles, dental labs, scuba diving fills.

Installation Requirements:

  • Indoor or sheltered outdoor use
  • Electrical: 400V/50Hz/3-phase (electric) or fuel supply (diesel)
  • 0.5 m clearance on all sides
  • Ambient: 0–40°C

Usage Notes:

  • At 25 bar operation, duty cycle is limited to 50%
  • Drain condensate every 8 hours
  • Replace filters every 500 hours
