Abstract

A multi-chamber canister for a pressure swing absorption system within a general housing assembly. The chambers include a first molecular sieve chamber for receiving a first molecular sieve for separating air from the ambient environment into a concentrated gas and at least a second molecular sieve chamber disposed within the housing assembly for receiving a second molecular sieve for separating air from the ambient environment into a concentrated gas component. Furthermore, a supply chamber is disposed within the housing for receiving air from the ambient environment and for communicating air to either first or second molecular sieve chambers.

Claims (15)

1. An absorption system for separating air into a concentrated gas component, said system comprising:

an air supply;

a compressor for receiving and compressing the air supply, providing a compressed air supply;

molecular sieve material for separating the compressed air supply into a concentrated gas component; and

an outlet delivering at least 10 liters per minute (LPM) of concentrated gas component from the molecular sieve material;

wherein the system has total volume; and

wherein the system has a specific volume per LPM≦0.42 ft 3 /LBM.

2. The system of claim 1 , wherein the system comprises a pressure swing adsorption system.

3. The system of claim 1 , wherein the molecular sieve material is a SILIPORITE® molecular sieve material.

4. The system of claim 3 , wherein the molecular sieve material is housed in two molecular sieve chambers.

5. The system of claim 4 , further comprising:

a housing of a general length including a housing wall;

a first molecular sieve chamber defined within said housing for receiving the molecular sieve material, the first molecular sieve chamber defined by a first molecular sieve chamber partition, wherein the first molecular sieve chamber partition and the housing wall define the first molecular sieve chamber;

at least a second molecular sieve chamber defined within said housing for receiving the molecular sieve material, the second molecular sieve chamber defined by a second molecular sieve chamber partition, wherein the second molecular sieve chamber partition and the housing wall define the second molecular sieve chamber; and

a supply chamber defined within the housing for receiving the compressed air supply and for communicating the compressed air supply to the first and the second molecular sieve chambers, the supply chamber defined by a supply chamber partition, wherein the supply chamber partition and the housing wall define the supply chamber, and wherein the supply chamber extends along a general length of the housing, the supply chamber including an air inlet for the air supply, the air inlet disposed a general distance apart from where the supply chamber fluidly communicates with either one of the first and the second molecular sieve chambers enabling the housing to act as a heat exchanger for cooling the air supply received from the air inlet.
