PURPOSE: A filtering apparatus for filtering a photoresist strip liquid of a PCB is provided to enhance the filtering performance by filtering effectively the sludge from the photoresist strip liquid. CONSTITUTION: A filtering apparatus for filtering a photoresist stripper of a PCB includes a main tank(3), a sludge barrel(5), a filter, a discharging plate(7), a pump(9), an auxiliary tank(13), a supply tube(11), and an on/off valve(15). The main tank(3) is adhered to a main body(1). The sludge barrel(5) is installed at the predetermined position apart from the main tank(3). The filter is installed between the main tank(3) and the sludge barrel(5). The discharging plate(7) is installed at a lower portion of the filter. The pump(9) is installed at a lower portion of the main body(1). The auxiliary tank(13) is connected to the main tank(3) through a connection tube(17). The supply tube(11) is used for supplying the photoresist stripper. The on/off valve(15) is installed at an entrance of the auxiliary tank(13).
