Claims26
1-64. (canceled)
An oxygen concentrator apparatus, comprising:
- at least two canisters;
- gas separation adsorbent disposed in at least two canisters, wherein the gas separation adsorbent separates at least some nitrogen from air in the canister to produce oxygen enriched gas;
- a compression system coupled to at least one canister, wherein the compression system compresses air during operation;
- a compressor outlet conduit coupling the compression system to at least one canister, wherein compressed air is transferred from the compression system to at least one canister through the compressor outlet conduit, and
- at least one air transfer device, wherein the air transfer device creates an air flow during use, and wherein the air transfer device is positioned such that the created airflow passes over at least a portion of the compressor outlet conduit.

An oxygen concentrator apparatus, comprising:
- at least two canisters;
- gas separation adsorbent disposed in at least two canisters, wherein the gas separation adsorbent separates at least some nitrogen from air in the canister to produce oxygen enriched gas;
- a compression system, the compression system comprising:
- a compressor coupled to at least one canister, wherein the compressor compresses air during operation;
- and
- a motor coupled to the compressor, wherein the motor drives the operation of the compressor;
- and
- a compressor outlet conduit coupling the compressor to at least one canister, wherein compressed air is transferred from the compressor to at least one canister through the compressor outlet conduit,
- wherein an outlet of one or more canisters is positioned such that gas exiting one or more canisters during a venting process is directed toward:
- at least a portion of the motor;
- at least a portion of the compressor;
- at least a portion of the compressor outlet conduit;
- or combinations thereof, during use.

- an air transfer device coupled to the motor, wherein the air transfer device creates an air flow when the motor is operated;
- wherein at least a portion of the compressor outlet conduit is positioned proximate to at least a portion of the motor;
- and
- wherein an outlet of one or more canisters is positioned such that gas exiting one or more canisters during a venting process is directed toward at least the portion of the compressor outlet conduit positioned proximate to the motor, and gas exiting one or more canisters during a venting process is directed toward at least a portion of the motor proximate to the compressor outlet conduit, during use;
- and
- wherein the air transfer device facilitates flow of gas exiting the canister during a venting process.
