<p>PROBLEM TO BE SOLVED: To solve the problem that all apparatuses generating drain are joined to an oil/water separator for separating foreign matter such as oils from the drain by drain pipes although drain generating amount of the apparatuses including an air tank, a dryer, an air filter, an after cooler which is not shown in conventional technology or the like are greatly different and consequently there is possibility of joining waste drain piping to apparatuses generating little drain and to solve the problem that although drain generating amount in the dryer is especially large, drain treatment making the most of the peculiarity is not carried out. SOLUTION: The dryer 31 having large drain ejecting amount and the oil/ water separators 50A, 50B for separating oil and water in the drain are joined by drain piping 121, 121a, 121b, 121c, 122, 124, 125, 126, 127, 128 and they are integrally constituted by being disposed on the same substrate 39 or by being housed in the same box 38. Thereby the drain from the dryer 31 is treated in the oil/water separators 50A, 50B.</p> |
