Piston compressor or reciprocating compressors and rotary screw air compressors are two of 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 and rotary screw air compressors and the capabilities of each technology is key. That’s why we’re covering the basics below!
The main difference between a screw and piston (reciprocating) compressor is the way they compress the air. Screw air compressors use two meshing helical screws, while piston air compressors use pistons driven by a crankshaft. Another difference is the moving parts as the screw compressor has two moving parts which are not in contact while the piston compressor has a lot of moving parts. The screw compressors operate at a lower temperature and integrate a good cooling system.
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.
Piston compressor a great option as an entry level compressor, but it's common for facilities outgrow the unit. If you need a consistent and or increased flow (CFM) and are looking for something that is compact, efficient, reliable and quiet, going with a rotary screw would be a great option. It’s quite normal for a company to start out with limited need for compressed air, but as production and customer demand increases, so does the need for increased output and the need for a larger compressor that can adequately handle the demand and increased duty cycle!
