Reciprocating air compressors have multiple parts that require frequent checks such as valves and piston rings. The up –and- down motion is known as the reciprocating motion. Improper use of the compressor might lead to corrosion of the metals. Another significant difference between rotary screw air compressors and reciprocating air compressors is that rotary compressors operate with a lot lower dBa than reciprocating air compressors. The reciprocating compressor often the best choice for applications that compress gases other than air, and that exceed or fall below the 100–150 psig range. When deciding whether to install a new engine driven air compressor or change your existing design, it’s essential to understand the operating characteristics, capabilities and limitations of the two alternative air compressors commonly considered. What is a Cooling Tower and How it Works? Both are designed to pressurize air for use in industrial applications, and both accomplish this task by sucking in atmospheric air, pressurizing that air in a cylinder and releasing that air for its end-point use. Rotary Screw Air Compressor vs Piston Compressor The two most popular types of compressors are rotary screw air compressors and reciprocating (or piston) air compressors. They are simple units, often mounted on a small receiver tank, and they usually run in start/stop mode on a mechanical pressure switch. It is easy to maintain the piston and the shafts since they both require care and maintenance. An electric motor turns the crankshaft which causes the piston to rise & fall within the cylinder, compressing the air. It is usually meant for sporadic use, especially when you need a smaller amount of air. Typically used in plant air applications for 125 to 150 psi(g) the practical discharge pressure limit for rotary screw air compressors is considered to be 250 psi(g). We will be happy to answer them.
