Does your company have an extensive compressed air system? If so, you may spend a lot of your operating expense dollars on compressor maintenance and upkeep. However, you can increase your efficiency and lower your maintenance costs when you have the right kind of compressor. The screw and reciprocating (piston ring) compressor are two of the most common types in service today. Here is information on them to help you decide which compressor is best for you.
Reciprocating Compressors
“Reciprocate” means to move back and forth or up and down in a straight line. These compressors use pistons attached to crankshafts. In fact, they are very similar to the components of a standard internal combustion engine. The main difference is there is no fuel burned, and the crankshaft in a piston ring compressor gets its power from an electric motor.
Screw Compressors
A screw compressor works on entirely different principles from reciprocating units. These compressors are also called rotary compressors because they use two rotors (side by side) turning in different directions. They get their name “screw compressors” because the rotors have ribs on them similar to threads on a screw. As the rotors turn, they trap air between the ribs and compress it.
Which is Best?
For many smaller and standard operations, a reciprocating or piston ring compressor can give you good service is slightly more efficient than screw compressors. However, if you have a large operation and need a constant supply of compressed air, you should consider the benefits of screw or rotary compressors.
Rotary compressors work with less vibrations and noise, so if noise is an issue, they are the best choice. Make sure to choose a trusted source for your compressor needs. This is very important for companies needing oil-free compressed air. Your compressor company can provide invaluable services.
