ABSTRACT:
A filter for removing micron and sub-micron molecular-sized particulate matter from a moving gas stream and comprising an enclosed filter module having a gas inlet for being connected to a source of gas to be filtered and gas outlet for discharging filtered gas from the module. A filter element is positioned in the filter module in gas flow interposed relation downstream of the gas inlet and upstream of the gas outlet in such manner that the gas must pass through the filter element in order to reach the gas outlet. The filter element comprises a multiplicity of hollow fibers each defined by a membrane wall formed of a microporous material surrounding a centrally-disposed lumen wherein filtration occurs by passing the gas from an upstream side of the hollow fiber through the membrane wall of the fibers to a downstream side thereof.
