Product Name: Atlas Copco PF3120SS4S7 — Oil-Free Piston Compressor

Product Overview:
A high-capacity oil-free piston compressor. The model code: PF3120 = 12 m³/min FAD, SS = stainless steel air end, 4 = four-stage, S7 = Elektronikon S7 controller.

Detailed content

Technical Specifications:

  • FAD: 12.0 m³/min (424 CFM)
  • Max Working Pressure: 10 bar / 13 bar / 16 bar
  • Motor Power: 110 kW (150 HP) electric
  • Cooling: Water-cooled
  • Sound Level: 88 dB(A)
  • Weight: ~3,800 kg
  • Air End MaterialStainless steel (AISI 316L)

Material Composition:

  • Cylinders: AISI 316L stainless steel
  • Piston rings: Carbon-filled PTFE
  • Valves: Stainless steel (AISI 316)
  • Frame: Epoxy-coated carbon steel

Structural Features:

  • SS = Stainless steel air end (corrosion-resistant)
  • S7 = Elektronikon Mark VII touchscreen controller
  • Four-stage compression
  • Water-cooled inter-stage + aftercooler
  • Integrated condensate drain

Working Principle:
Four-stage oil-free piston compression. Stainless steel air end provides superior corrosion resistance. Water-cooled inter-stage coolers reduce discharge temperature. S7 controller manages pressure, temperature, and alerts.

Key Advantages:

  • Stainless steel air end — resists corrosive environments
  • S7 controller: predictive maintenance, energy optimization
  • Class 0 air quality
  • 12 m³/min FAD — highest in this series

Applicable Industries:
Chemical processing, marine/offshore, food & beverage, pharmaceuticals, electronics, painting with aggressive solvents.

Installation Requirements:

  • Reinforced floor (3,800 kg load)
  • Water supply: 25 L/min at 25°C inlet
  • Electrical: 400V/50Hz/3-phase, 200A supply
  • Ambient: 0–40°C

Usage Notes:

  • Stainless steel air end requires no special coating maintenance
  • S7 controller logs 500+ operating parameters
  • Schedule water treatment to prevent scale in coolers
