Air separation modules and methods of removing condensate from air separation modules

An air separation module, comprising:

• a cylindrical canister having a longitudinal axis, an inlet, an oxygen-depleted air outlet, and a drain portion with an oxygen-enriched air outlet;
• a separator 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;
• and
• a sump portion fluidly coupling the drain portion to the cylindrical canister, wherein a first end of the sump portion is arranged within the cylindrical canister and the sump portion extends radially from an outer surface of the cylindrical canister, and the drain portion is connected to a second, opposite end of the sump portion;
• wherein the drain portion extends tangentially from the cylindrical canister to issue the oxygen-enriched air flow fraction and entrained condensate from the oxygen-enriched air outlet with a tangential flow component.
