Our dedicated team of technicians ensures that your air compressor system functions perfectly, assuring maximum energy efficiency and uptime.
Understanding the working principles of air compressors is vital for maximizing their efficiency and performance.
Air Compressor Working Principle
At the core, an air compressor converts external power sources, such as electricity or a combustion engine, into potential energy stored in pressurized air.Â
1. Intake of Ambient Air:
The compressor draws in ambient air from the environment through an inlet valve, often using a filter to ensure clean air.
2. Compression Process:
The trapped air is then compressed by the movement of a piston or rotary element within a compression chamber, reducing its volume and increasing its air pressure.
3. Storage of Compressed Air:
The compressed air is stored in a storage tank or air tank for later use, maintaining a reservoir of high-pressure air.
4. Release and Usage:
When needed, the discharge valve releases the air to power tools, pneumatic tools, spray guns, or nail guns, depending on the industrial application.
Air Compressor Types
Learn about the four main air compressor types, their advantages and disadvantages over each other, and how to pick the right one according to your requirements.
| Type | Category | Working Principle |
| Piston (Reciprocating) Compressor | Positive Displacement | Gas is drawn into a cylinder and compressed by a reciprocating piston driven by a crankshaft. |
| Screw Compressor | Positive Displacement | Two intermeshing helical rotors rotate in opposite directions, trapping and reducing the volume of gas between them. |
| Centrifugal Compressor | Dynamic (Turbo) | A high-speed impeller accelerates gas outward; the kinetic energy is then converted to pressure in a diffuser. |
| Scroll Compressor | Positive Displacement | An orbiting scroll moves eccentrically against a fixed scroll, creating moving crescent‑shaped pockets that progressively shrink to compress gas. |
| Axial Compressor | Dynamic (Turbo) | Gas flows axially through alternating rows of rotating and stationary blades, which add energy and increase pressure gradually. |
Air Compressor Maintenance Tips
To maximize the lifespan of your air compressor, especially during the first 7 to 8 years, proper maintenance is key. With good care, compressors can deliver 10 to 15 years of reliable performance. Regular maintenance is crucial to ensure the longevity and optimal performance of air compressors. Here are some tips:
Regular Inspection
Reduced energy consumption without compromising performance. Atlas Copco’s compressors are equipped with innovative technology that optimizes energy use, resulting in lower operating costs.
Genuine Parts
Always use genuine parts from Atlas Copco to maintain the integrity of the compressor. Using non-genuine parts can compromise the performance and safety of the compressor.
Servicing
Follow the manufacturer’s guidelines for servicing schedules. Regular servicing by trained professionals helps to detect and address issues before they become major problems, ensuring reliable operation.

Air Compressor Oil, Lubricants and Fluids
Air compressors need specific lubricants and fluids to achieve maximum uptime, performance and lifetime. Air compressor oils and fluids cover all your needs.
- Unique mix of additives
- Preventing wear
- Compatible with all parts
To keep your air compressor operating reliably and cost-effectively, oil plays multiple vital roles. It protects rotating parts to avoid metal-to-metal contact. It absorbs the heat to ensure optimal working temperatures. It seals the clearances between the rotors and the housing, preventing air backflow and reduced output. Finally, it absorbs contaminants or carries them off to the oil filter.

Frequently Asked Questions
Find clear answers to common questions about orders, shipping, returns, payments, and our services, helping you enjoy a smooth and confident shopping experience.
What is the working principle of an air compressor?
An air compressor draws ambient air through an inlet valve, compresses trapped air in a compression chamber via a piston compressor, a rotary screw compressor, or a centrifugal compressor, stores it in an air tank, and delivers high-pressure air for pneumatic tools, power tools, and industrial applications.
What are the main types of air compressors?
Types include positive displacement compressors (reciprocating compressors, piston air compressors, rotary compressors) and dynamic displacement (centrifugal compressors, axial compressors) for high-pressure output, continuous operation, and energy savings.
Why choose genuine air compressor parts?
To keep your compressor in good shape, genuine parts are the way to go. As they are designed specifically for your compressor, they give the reliability, long lifetime and energy efficiency you expect.
Operating conditions play a crucial role for the lifetime of your air compressor and its components. Air compressor oils and filtration parts serve as the first and most important barrier to protect the machine. That is why it is key to safeguard the performance, reliability and lifetime of your air compressors with genuine parts. Developed in-house and thoroughly tested, our genuine parts protect you from premature and avoidable compressor failures.
How do rotary screw compressors differ from reciprocating compressors?
A rotary screw air compressor uses rotors for constant flow, reliable performance, and low energy costs, while a reciprocating air compressor (piston moves downward) delivers high-pressure air for nail guns, spray guns, and heavy-duty industrial applications.
How to choose the right air compressor?
Select based on air pressure, flow rate, and application: rotary screw compressors or centrifugal compressors for continuous operation; piston compressors or two-stage compressors for high pressure; consider oil-free air, storage tank size, and energy costs.
How to size my compressor?
Choosing the right compressor depends on three key factors: flow, pressure, and application. Together, they define how much air you need, the force required to perform the task, and how the compressor will be used over time.
