Furthermore, the tanks are located near uses characterised by highly variable air requirements in order to limit pressure fluctuations along the distribution lines. Optimum tank volume in a production system depends on the type of compressor, environmental conditions of operation and type of use. In systems characterised by max operating pressure of 10 bar and flow rates from 1 to 100 Nm3/min, tank capacity is calculated, as a first approximation, with the following relationship: Tank Pre filter Services Filters Air Dryer Compressor Draining Drain Treatment 213 V= 0.2 to 0.6 Q V = theoretical volume of the tank in m3 Q = intake flow rate from the compressor in m3/min 0.2 = coefficient for large plants 0.6 = coefficient for small plants COMPRESSED AIR Model
