An example air separation module includes: a housing; a bundle of hollow fibers disposed within the housing, wherein the bundle is configured to receive inlet air and separate the inlet air into an oxygen-rich portion and a nitrogen-rich portion; an inlet tubesheet coupled to a proximal end of the bundle and configured to block respective spaces between the hollow fibers of the bundle, wherein a first side of the inlet tubesheet is configured to be subjected to the inlet air before flowing through the bundle, while a second side of the inlet tubesheet is configured to be subjected to the oxygen-rich portion having a lower pressure compared to the inlet air such that the inlet tubesheet is subjected to a pressure load; and a support member disposed downstream of the inlet tubesheet and abutting against the inlet tubesheet to support the inlet tubesheet against the pressure load.

Disclosed is an ozone reduction device used to reduce an ozone provided by an ozone source into an oxygen. The ozone reduction device comprises a gas inlet duct, a gas delivery tube, a heating element and a gas outlet duct. The gas inlet duct is communicated to the ozone source. The gas delivery tube introduces the ozone provided by the ozone source through the gas inlet duct, and the gas delivery tube transports the ozone along a spiral delivery path. The heating element is used to provide a thermal energy to heat the ozone transported by the gas delivery tube, so that the ozone is heated by the thermal energy and reduced to an oxygen when flowing along the spiral delivery path. The gas outlet duct is communicated to the gas delivery tube and used to discharge the oxygen obtained by reducing the ozone.
