Abstract
Filter apparatus and method comprising a pair of filter shells having communicating flow passages and a filter media between the shells. Upon the clogging of the filter media, the inflow of liquid is stopped, the shells drained of remaining liquid and separated to allow the filter media to be removed and replaced. The shells can be interlocked when closed, and a mechanism is provided to hold one shell in locked engagement against the other when filtering. The one shell can then be released to allow the shells to separate when the filter media is to be replaced.
