Start a quote02 / Choosing a compressor
Choosing the right
air compressor.
The right compressor depends on how much air your work needs, at what pressure and for how long. These are the questions we start with.
Pressure (PSI)
Look for the CFM you need delivered at the pressure your tools require. A higher maximum PSI does not mean more usable airflow.
Duty cycle
Steady, all-day demand calls for a compressor built for continuous duty. Occasional bursts of air use may suit a machine built for intermittent use.
Power supply
Know the voltage and phase available for an electric compressor, or the fuel for an engine-driven one, before you choose.
Tank and air quality
A larger tank covers short bursts but does not add airflow. Filters and dryers help protect tools from moisture and oil.
Where it will work
Tell us where the compressor will sit: indoors or outdoors, how well it is ventilated and the temperatures it will face.
03 / Compressor types
Rotary screw or
reciprocating?
Both types have a place. The right one depends on how your work uses air.
Rotary screw compressors
Built for steady, continuous demand and long run times. Usually quieter than a piston compressor, with a higher purchase price. A good fit when air has to be available for long stretches.
Reciprocating (piston) compressors
Often chosen for shops and jobsites where air use comes in bursts, and usually less costly to buy. Typically louder than a rotary screw machine, and not meant to run nonstop.
Exact capabilities vary by model and manufacturer. We’ll match the compressor type to your work.

Compressor sales questions.
Is Flatland Supply an authorized air compressor dealer?
Yes. Flatland Supply is an authorized dealer for Compressed Air Systems, Cast-Air and Ingersoll Rand.
What size air compressor do I need?
Start with the tools or equipment you’ll run, the number of people using air at once and whether the work is occasional or continuous. Then confirm the CFM delivered at the pressure you need, duty cycle, tank storage, available power and air treatment. Our CFM calculator gives you a planning starting point, and we’re happy to review it with you.
Should I choose a rotary screw or a reciprocating compressor?
Rotary screw compressors are built for steady, continuous demand. Reciprocating (piston) compressors are often chosen where air use comes in bursts. The right choice depends on your work, so tell us how you’ll use the air.
What do you need for a new compressor quote?
Start with the tools or equipment you’ll run, required airflow and pressure, available power, daily run time and installation location. If you’re replacing a compressor, include its specifications.
Do you have compressors in stock?
Equipment availability and lead time are confirmed with your quote. Call or send your requirements and we’ll tell you what is available.
