A compressor is a mobile or stationary machine that produces compressed air through compression. This kind of stored energy is essential for many industrial companies, for example in cleaning, painting or checking weld seams. Mobile compressors are broadly divided into piston and screw compressors, and can be either oil-lubricated or oil-free. The basic principle always remains the same: intake air is compressed, then it is freed from moisture and finally it is stored in a compressed air tank. You will find second hand compressors from manufacturers such as KAESER, ATLAS COPCO or BOGE
Pros and cons of compressors
Compressors supply a relatively safe form of energy. Compressed air is not dangerous unless applied to bodily orifices. However, all new employees should be informed of this. Compressed air machines have a wide range of uses. Cleaning with compressed air is particularly efficient because the swirling air can reach even the inaccessible crevices of a machine. When cleaning high-purity environments, pure and filtered compressed air is the only alternative.
A disadvantage of compressors is that the energy created is the most expensive form of energy in industrial use. When you take a closer look at the air compression process, the reason for this is clear: electrical energy is first turned into mechanical energy, and then compressed air. Because air is a compressible gas, only a fraction of the compressed air is used for the purpose intended, particularly when it has to be redirected over a long distance. The use of compressed air is necessary in modern industrial production, but the costs can be reduced drastically with intelligent management. Often it pays to use more than one compressor, if this means avoiding long pneumatic lines and hoses.
