According to an embodiment of the present invention specification, a separator cooler unit comprises: a separator cooler for filtering foreign substances from supplied gas and discharging them at the same time; a drain valve for opening and closing a foreign substance discharge passage; and a noise remover which is installed at the end part of the foreign substance discharge passage for reducing the noise generated by the foreign substances being discharged with gas. The noise remover comprises: a noise remover housing having a drain port connected to the foreign substance discharge passage; a fixing pin which is fixed and arranged in the longitudinal direction at the center of the train port; a porous hole plate which is arranged to block the entrance of the drain port by being fixed on one end of the fixing pin and which has multiple through holes; and a diaphragm which is adhered closely to the outer periphery of the noise remover housing for blocking the exit of the drain port and which discharges the gas and foreign substances by forming a gap between the outer periphery. Hence, the foreign substances and gas which are passing through a drain port having relatively big inner diameter, pass through the through holes on the porous hole plate, which reduces the noise for the first time; and they passes through the gap between the diaphragm and noise remover housing, the noise is reduced for the second time. |
