Abstract: An air separation module includes a cylindrical canister and a separator. The cylindrical canister has a longitudinal axis, an inlet, an oxygen-depleted air outlet, and a drain portion with an oxygen-enriched air outlet. The separator is arranged within the cylindrical canister to separate a compressed air flow into an oxygen-depleted air flow fraction and an oxygen-enriched air flow fraction, the oxygen-depleted air flow fraction provided to the oxygen-depleted air outlet and the oxygen-enriched air flow fraction to the drain portion of the canister. The drain portion extends tangentially from the cylindrical canister to issue the oxygen-enriched air flow fraction with entrained condensate from the oxygen-enriched air outlet with a tangential flow component. Nitrogen generation systems and methods of removing condensate from air separation modules are also described.

Abstract: An air separation module includes a separator, a canister, and a nominal-length end cap. The separator is arranged to separate ambient air into an oxygen-enriched air fraction and a nitrogen-enriched air fraction. The canister supports the separator and has a canister end flange, a canister intermediate flange and a canister end, the canister intermediate flange arranged between the canister end flange and the canister end. The nominal-length end cap is fixed to the canister end flange, and the separator extends between the canister end flange and the canister end. Nitrogen generation systems and methods of generating nitrogen-enriched air flows are also described.

Abstract: An air separation module includes canister, a separator, and a band. The canister has an inlet end, an axially opposite outlet end, and an oxygen-enriched air flow fraction outlet port between the inlet end and the outlet end of the canister. The separator is supported within the canister and is arranged to separate compressed air flow into an oxygen-depleted air flow fraction and an oxygen-enriched air flow, provide the oxygen-depleted air flow fraction to the outlet end of the canister, and divert the oxygen-enriched air flow fraction to the oxygen-enriched air flow outlet port. The band is fixed to the canister and extends about the separator at a location axially between the oxygen-enriched air flow fraction outlet port and the inlet end of the canister to support the air separation module. Nitrogen generation systems and methods of making air separation modules are also described.

Abstract: An air separation module includes a canister extending between a first end and an opposite second end, a separator fixed within the canister to separate a compressed air flow into an oxygen-enriched air flow fraction and an oxygen-depleted air flow fraction, and a one-piece cap. The one-piece cap is connected to the first end of the canister and has a filter module mount portion on a side of the one-piece cap opposite the separator to support a filter module with the air separation module. Nitrogen generation systems and methods of making air separation modules are also described.
