Air Compressor Basics and How They Work
An air compressor is a machine that takes in ambient air, compresses it to a higher pressure, and stores it in a tank for later use. This compressed air acts as a powerful energy source for a wide range of tools and industrial processes. When selecting a unit, understanding its core specifications is crucial.
- Horsepower (HP): This measures the power of the compressor's motor. While important, it's not the sole indicator of performance.
- CFM (Cubic Feet per Minute): This is the volume of air the compressor can deliver at a specific pressure level. It is arguably the most critical specification to match to your tool requirements.
- PSI (Pounds per Square Inch): This refers to the amount of pressure the compressor can generate. Most tools operate within the 90-100 PSI range, but some applications require higher pressure.
- Duty Cycle: This tells you how long a compressor can run continuously within a given timeframe without overheating. A 50% duty cycle means it can run for 30 minutes out of every hour, while a 100% duty cycle means it can run non-stop.
Matching these specs to your operational needs is non-negotiable. If your compressor's CFM output is lower than your tools' combined demand, you will experience a drop in performance and efficiency. Answering the question "what air compressor do I need?" starts with a clear understanding of your tools' air requirements.
How to Choose the Right Air Compressor
Choosing the right air compressor for your business isn’t just about price; it’s about evaluating your tools and needs to support your operations.
- Determine Your Required Airflow (CFM) & Pressure (PSI): List every air tool and piece of equipment you will use. Find the CFM and PSI requirements for each (usually on the tool or in its manual). Add up the total CFM for all tools that will run simultaneously. As a rule of thumb, add a 30% buffer to this total to account for future growth and air leaks.
- Match to Appropriate Compressor Type: Once you have your needs, search the Air Compressors section on AirCompressors.com and filter by your CFM needs. For smaller industrial jobs or intermittent use, choose a two-stage reciprocating piston unit. For continuous operation, high air demand, and energy efficiency, choose a rotary screw compressor.
- Consider Space, Power Supply, and Duty Cycle: Once you have units in mind, measure the available floor space and check if you need a vertical or horizontal tank. Confirm you have the correct electrical service (voltage and phase) for the compressor you choose. Match the compressor's duty cycle to your operational needs to prevent premature failure.
- Think About Extras: Determine if you need clean, dry air. If so, plan for air dryers and filtration. Consider purchasing maintenance kits upfront to ensure you have everything needed for routine service.
By following these steps, you can confidently select the right air compressor that will support your business needs and ensure an efficient, reliable operation.

Compressor Features Explained
Understanding advanced features helps you answer, "what kind of air compressor do I need?" for your specific application.
- Single vs. Two-Stage Reciprocating - A single-stage compressor pressurizes air in one step. A two-stage compressor, like the Quincy QP/QT series, compresses the air twice to a higher PSI. This two-stage process runs cooler and more efficiently than single-stage models, making it better for demanding industrial use.
- Rotary Screw Benefits - Unlike pistons, rotary screws provide a continuous, non-pulsating stream of air. Their design allows for a 100% duty cycle, making models like the Atlas Copco GA series ideal for manufacturing lines or automotive shops that run air tools all day. They are also significantly quieter.
- Variable Speed Drive (VSD) - Conventional compressors run at full speed or not at all. A VSD compressor, such as the Atlas Copco GA22-37 VSD, adjusts its motor speed to precisely match the real-time air demand. This eliminates wasteful idling and can reduce energy costs by up to 50%.
- Integrated Dryers - Moisture in compressed air can damage pneumatic tools and compromise processes like painting or sandblasting. Compressors with integrated dryers, like the Atlas Copco GA26VSDS, remove this moisture to deliver clean, dry air, protecting your equipment and final product.
By understanding these key compressor features, you can make a well-informed choice that ensures optimal performance and efficiency for your industrial or commercial needs.
Compressed Air Accessories & System Components
An air compressor is only one component that supports your operations. A complete compressed air system supports everything after the air is generated, including moisture removal, filtration, pressure stability, piping losses, system leaks and more.
When buying an air compressor, consider these essential components to build a complete, efficient, and reliable solution:
- Air Dryers & Filtration: Protect your investment by ensuring your compressed air is dry and free of contaminants.
- Lubricants & Service Kits: Using the correct OEM lubricants and service parts is the best way to keep your compressor running efficiently and maintain its warranty.
- Piping & Fittings: An efficient compressed air distribution system is just as important as the compressor itself. AIRpipe's aluminum piping solutions are leak-free, easy to install, and maximize airflow.
- Part Kits: Keep essential replacement filters and parts on hand to minimize downtime during scheduled maintenance.
