フイルタ切換装置。 A filter switching device in which a main filter circuit having a main filter for passing and filtering fluid and a sub-filter circuit having a sub-filter are provided in parallel, and when the main filter becomes clogged, the main filter circuit can be switched to the sub-filter circuit. An electromagnetic switching valve for switching between the two filter circuits is provided on the upstream side of the two filter circuits, and a pressure detector is provided for detecting the increased pressure when the main filter is clogged. A filter comprising: a controller that receives a signal and supplies a switching signal to the electromagnetic switching valve; and when the main filter becomes clogged, the filter automatically switches from the main filter circuit to the sub-filter circuit and uses the sub-filter. Switching device.
