The compressor should be selected specifically for the requirements of the technological process in which compressed air is used. The choice between a reciprocating or screw compressor mainly depends on the compressed air consumption. When the consumption of compressed air exceeds 800 l / min at a pressure of 7 bar, your interest should be directed to screw compressors, because only they will enable the production of such an amount of compressed air in a continuous manner without losing the durability of the compressor. When we use compressed air max. up to 800 l / min at 7 bar in a very cyclical but not continuous manner, a reciprocating compressor will be a good choice, which is cheaper to buy and operate.
