PURPOSE: A device for testing filter is provided to selectively test more than one oil filters under real conditions of flux and pressure. CONSTITUTION: A device includes a first and a second oil filter testing lines. The first oil filter testing line is placed on an oil piping(11) connected with a tank and includes an oil pump(13); a flow meter(14); a first oil filter(15); and manometers(16,17). The oil pump is driven by a motor(12). The second oil filter testing line is placed on a branched piping(18) branched from the oil piping and includes an oil pump(20); a flow meter(21); a second oil filter; and manometers(23,24). The oil pump is driven by a motor(19). A check valve(27) is installed on the branched piping of the second oil filter testing line before the pump to selectively supply the piping of the first oil filter testing line and the branched piping with oil from the tank. A microprocessor and a controller are included to receive data from the manometers and flow meters and to control the motors and check valves according to preset program to set up the first and the second oil filter testing line to be under real using conditions.
