Abstract: A device for separating components of a gas mixture includes a hollow housing having a body portion at a first end, a separable end cap at a second end, and at least one side wall. The housing has an inlet port for the gas mixture, a permeate outlet port for gas mixture enriched with a first component of the mixture, and a retentate outlet port for gas mixture enriched with a second component of the mixture. An insert within the housing comprises a plurality of hollow fibres of a material which are more permeable to the first component than the second. The housing defines passageways for gas to flow between the inlet port and the permeate and retentate outlet ports. The insert is fastened to the end cap at least temporarily so that the insert is withdrawn from within the housing when the end cap is removed.
