    摘要: A filtering apparatus for indicating the degree of exhaustion of an adsorption filter which includes a mechanical filter and a pressure meter for detecting the difference in pressure between a point downstream and a point upstream of the mechanical filter to provide an indication of the degree of exhaustion of the adsorption filter. The mechanical filter may be an internal type filter or a surface filter and it may be either series-connected or connected in shunt with the flow path of the adsorption filter.
