SELECT THE RIGHT COMPRESSOR FIRST TIME It is crucial for any workshop that the chosen compressor fits the need optimally. An undersized solution quickly becomes an annoyance, while an oversized compressor is not profitable in the long run. Before you decide, you should therefore consider the following elements. Air volume and working pressure The first thing to consider before choosing a new compressor is the amount of air you need, as well as the required working pressure. Should the compressor supply one workstation or more; how many must be able to use the compressor at the same time; and what should the com- pressed air be used for? If the compressor is to ”only” operate smaller compressed air tools, the need is limited, but if the air is to be used for painting, for example, you need longer-lasting pressure. Usage situation Next, clarify the usage situation, including the physical location of the compressor. If the com- pressor is located close to the workstations, noise and odor nuisance must be taken into account. Should the compressor be mobile so that it can be moved around the workshop or installed in service cars? Air quality Finally, it is important to consider whether there are special requirements for air quality. If the compressed air is used in connection with painting, the air must be free from contamination, and finishing with e.g. filter is therefore necessary. PISTON OR SCREW COMPRESSOR? The choice between a piston and screw compressor depends primarily on the degree of load. In a piston compressor, the air is compressed with one or more pistons. These are suitable for compressing at intervals and the load factor should not exceed 50-60%. The screw compressor, on the other hand, is optimized for conti- nuous operation and can withstand a load ratio of 100%. Here the air is compressed by means of two opposite rotating screws. In addition, approx. 30% in energy by a screw compressor relative to a screw compressor. RENO - AUTO BROCHURE 3
