P: Oil-free reciprocating piston compressors, up to 40 bar (580 psig), 37-275 kW / 50-368 hp.

Atlas Copco’s P oil-free reciprocating compressors are a reference in the market for reliability and low cost of ownership. They deliver high-purity oil-free air for discharge pressures between 25 and 40 bar. Sturdy and designed for continuous industrial operation, P compressors deliver air safely, constantly and at low cost. Up to 160 kW, P compressors come as very compact 3-stage machines. Above 160 kW, with the addition of an oil free screw unit in the first stage, they come as 4-stage machines. This innovative approach results in unrivalled benefits, maximizing flow in compact plug & play units.

Customer benefits

  • Certified 100% oil-free – P compressors provide you with 100% pure, clean air that complies with ISO 8573-1 CLASS 0 (2010) certification. CLASS 0 means zero risk of contamination; zero risk of damaged or unsafe products; zero risk of losses from operational downtime; and zero risk of damaging your company’s hard-won professional reputation. In 2006 Atlas Copco was the first manufacturer in the world to receive such certification on an oil-free compressor.
  • Maximum energy savings Reciprocating technology ensures excellent volumetric efficiency and economic operation in terms of energy. In addition, with the Elektronikon® controller you can adjust the required discharge pressure between 25 bar (362 psig) and 40 bar (580 psig) to reduce energy costs.
  • Advanced control and monitoring –The advanced Elektronikon® system helps you keep control of costs by monitoring overall system performance through service indications, malfunction alarms and safety shutdowns.
  • High reliability – Low piston speed and low inter-stage temperatures preserve the internal components. The horizontal design ensures low vibration/pulsation levels for increased reliability. Design is close to API 618.
  • Low maintenance –The horizontal design is safe and comfortable for operators and maintenance personnel. Long service intervals reduce maintenance time and cost.
  • Easy installation -Each P compressor is delivered as a complete package with no reassembly on site. Installation is fast, straightforward and safe. P compressors are fitted on a skid and can be installed on a suitable industrial floor with chemical bolts. This eliminates skid vibrations and preserves the motor and mechanical parts.
