High-pressure oil-free air piston compressorsP compressor range25-40 bar / 50-60 Hz / 37-160 kW

By combining the right mix of innovation, high-tech components and a simplified, user-oriented design, Atlas Copco’s P compressor range is ready to be your partner for excellence. P compressors give the highest possible quality and reliability for your process, while offering the lowest possible operational costs.

Proven reliability at the lowest operational cost

PET bottle production High-pressure oil-free performance

Aeronautics High-pressure that can be trusted

Non-woven manufacturing Superior technology as a first choice

Food and non-food sectors Filling a wide variety of requirements

For PET bottle production, the total absence of oil or pollutants in process air is critical. Atlas Copco’s P compressors not only deliver high-quality air; they offer the reliability, efficiency and high productivity you expect from your equipment.

Test benches in the aeronautic industry require the best compressed air technology available. With their sturdy construction and trusted delivery of high-pressure oil-free air, P compressors are the ideal solution for these environments.

Advancements in the non-woven industry have led to many high-quality non-woven products being used in a wide range of applications. Producing these non-woven products requires oil-free high-pressure technology, which makes P compressors the first choice.

High-pressure oil-free air is used in many sectors, such as PET containers for pharmaceuticals, cosmetics, home care products and food and solar energy and electronics. With their steady oil-free air flow, our P compressors are best equipped to serve these markets.

A main requirement for your business is to reduce costs. The right air compressor can be a substantial source of savings for your production process. P compressors help you reduce costs in all areas, from installation to energy usage to maintenance, while still delivering the quality and reliability your process demands.

Driving down costs

Helping you make the right choice

The technical data for our machines are measured according to ISO 1217 Ed. 4, which stipulates that the FAD measurement is given at the outlet of the compressor, net of all losses. So you always see the real capacity you will receive, not a theoretical airflow that ignores system leakages. This means you get the optimum machine for your process, which leads to substantial benefits and reduced costs.

An optimum design

Intake volumeIntake volume - l/s - m3/min - cfm

External leakage External leakage Net usable air

Delivered volumeFAD - l/s - m3/min - cfm

Horizontal design: The completely horizontal design of our P compressors allows for a very low level of vibrations. This maximizes the reliability of the compressor and ensures a longer life for your components.

Three compression stages: With only 3 compression stages, fewer components are involved. This optimized design allows for a lower product cost and keeps service costs to a minimum.

Inlet flow refers to the suction flow at the 1st stage. This means you pay for mechanical losses!

FAD is measured according to ISO 1217 Ed. 4. This means a P compressor truly delivers what is promised.

Driving down maintenance costs

Adapting pressure to save energy

Keeping installation costs to a minimum

For our customers’ benefit, P compressors are specially designed to simplify maintenance on site, helping to reduce costs:

Maximum standardization of components, including cylinders, valves and packings, throughout the range for ▸simpler spare parts management, faster deliveries and reduced costs.

Horizontal layout for full accessibility to all components at an optimal height, particularly the cylinder heads and valves. ▸

In PET bottle production, the required air pressure changes, depending on the size and shape of the bottles being produced. You can adjust the pressure with the Elektronikon® controller to the required value between 25 bar (362 psig) and 40 bar (580 psig) to suit the demand. This allows you to optimize energy usage and drive down energy costs.

Every P compressor is delivered fully assembled. With no reassembly of components on site, installation is fast, straightforward, safe and without any unwelcome surprises. P compressors can be fixed to a suitable industrial floor using chemical bolts. This eliminates skid vibrations and preserves the motor and mechanical parts.

To manage your compressor in the most cost-efficient way and obtain the highest return on investment, Atlas Copco provides you with next-generation energy saving control systems. ES controllers keep your network running within a narrow, predefined pressure band. This increases the stability of the process and optimizes overall energy consumption.

Easy day-to-day operation

Closer control through advanced technology

Reduced maintenance costs Enhanced remote control

Delivering the comprehensive control features required in larger installations of mixed-sized machines, ES 8 is able to closely manage a maximum of 8 machines. This totally flexible controller provides significant cost savings through energy reduction and maintenance optimization.

Comprehensive, flexible machine sequence control ensures the installed machines are able to work in groups. ES guarantees that system running hours are equal across all machines in the same group. The result? Fewer service visits and reduced costs as all machines can be serviced at the same time. As ES automatically shuts down machines during ‘non-production’ times, running hours and service costs are further reduced.

If remote monitoring is required, there is no better alternative: the communication modules for MODBUS or PROFIBUS allow for integration in plant control systems. With the addition of one ComBox, an Elektronikon® installation can be accessed directly from a PC or via an existing building management system, using a choice of protocols.
