Piston (or reciprocating as they are also known) compressors and rotary (or screw as they are also known) air compressors are the most popular compressor technologies available today. But do you know which one would be better suited for your specific needs and applications? Understanding the difference between piston, rotary or screw air compressors and the capabilities of each technology is key. That’s why we’re covering the basics below!
What Factors Should I Consider?
Initial and operating costs, energy efficiency, duty cycle, and service intervals are important factors to consider when determining whether your business will benefit most from a piston or a rotary screw compressor. Noise levels is an additional factor to take into consideration.
- Initial Cost vs. Operating Costs. Budgeting for a compressor shouldn’t only include how much you pay for your compressor upfront; but keep in mind how much you’ll pay for your compressor in the long run (i.e. your overall operating costs). As much as 70-75% of a compressor’s lifetime operating costs are spent on energy usage, so keep that in mind when selecting a compressor technology. Pistons have a lower initial cost than screws, but screws cost much less to operate over time.
- Energy Efficiency. If both a piston and a screw were running the same amount of hours, the screw compressor will be much more efficient and have lower operating costs than the piston over the lifetime of the compressor. When selecting a technology, ask yourself: Is the initial or lifetime cost more important to you and your business?
- Duty Cycle. Because piston compressors are limited in their duty cycles, they’re ideal for applications with low duty cycle requirements and low daily running hours. Screw compressors, however, have long duty cycles. In fact, screws are engineered to run 100%, all day, every day!
- Service Intervals. There are more moving parts in a reciprocating compressor than in a screw, which results in increased machine wear and tear. Screw compressors don’t have as much wear; hence, they have reduced maintenance needs. But keep in mind that it’s important to keep any type of compressor on a consistent maintenance schedule! This will help ensure machine efficiency and optimal system performance.
- Noise Levels. Piston air compressors are loud, If noise level matters, think about a screw compressor.

What size air compressor do I need?
|
Karen Destajo
In choosing the size of an air compressor, it is important to think of how many air tools or what kind of air tools you are going to run. Your air compressor should be able to meet the air requirement of your air tools such as the paint guns, impact wrenches, air nailers, and tyre inflators. You need to buy one that's the right size and is powerful enough to do the job.
Basically, you'll need to ask yourself a few questions like, 1. )What types of air tools will you use? Are you going to be sanding and painting? or use wrenches and nailer? Generally speaking, tools such as those that require constant supply of air, you will need a compressor with a bigger tank. And the more power your tools need to put out, the more airflow that your compressor will need to supply efficiently. 2. ) How much space do you have to fit the air compressor perfectly into your workshop and lastly, 3. ) Where do you intend to use it? Once you figure this out, you can have a clearer idea of what size of air compressor is right for you.

What types of air compressors are there?
|
Nick Coulson
Most air compressors are either reciprocating piston type or rotary screw. Centrifugal compressors are common in very large applications. There are two main types of pumps either oil or oil-less. The main difference between rotary and reciprocating compressors are the rotary compressor use an impeller which is in a rotary motion to compress the air while a reciprocating compressor involves a piston-cylinder device in which air is filled and compressed due to the upward movement of the piston. However reciprocating compressors are marginally more efficient because they compress the same amount of gas with 5 to 10 per cent less energy input. However, since this difference is so marginal, most small-to-medium level users are best off using rotary type.

What air flow is required
|
Nick Coulson
When selecting an air compressor you need to identify the PSI and CFM requirements of your air tools. If you will only be using one tool at a time use the tool with the highest PSI and CFM requirement. If you intend to run multiple tools at the same time you will need to total the CFM's required by each tool. Here are some examples: Angle Disc Grinder 6 CFM Dual Action Sander 6 CFM Ratchet 1/4" 3 CFM Air Drill 1/2 4 CFM Grease/caulking Gun 4 CFM Ratchet 3/8" 4 CFM Air Drill 3/8 4 CFM High-Speed Grinder 5" 4 CFM Sand Blaster (11 L) 4 CFM Butterfly Impact 3 CFM Impact Wrench 1/2" 5 CFM Spray Gun (commercial) 6 CFM Chisel/Air Hammer 4 CFM Impact Wrench 3/4" 7 CFM Spray Gun (HVLP) 18 CFM

What Air Compressor do I need?
|
Nick Coulson
Compressors are measured in two main ways, PSI (pounds per square inch) and deliverable CFM (cubic feet per minute). These measurements determine the effectiveness of the air compressor in different situations. For example single tool use: A 1/2" impact wrench needs 5.0 CFM at 90 PSI, then the compressor should deliver between 6.25 - 7.5 CFM at 90 PSI. If you plan to run more than one tool at the same time, you must add the CFM of each tool together to determine your needs.
