Title (EN) APPARATUS AND METHODS FOR CLEANING AND OXYGEN-ENRICHING AIR
(FR) APPAREIL ET PROCÉDÉS D’ÉPURATION ET D’ENRICHISSEMENT EN OXYGÈNE DE L’AIR
Abstract: front page image
(EN)A portable breathing apparatus for oxygen enrichment of breathable air comprises: an adsorption vessel; an air compressor for pumping air into the adsorption vessel; a valve for purging pressure from the adsorption vessel; an adsorbent disposed within the adsorption vessel adsorbing a non-oxygen constituent of air when the vessel is pressurized, thereby producing oxygen-enriched air, and desorbing the non-oxygen constituent when the pressure is purged.
(FR)La présente invention concerne un appareil respiratoire portatif pour l’enrichissement en oxygène d’air respirable qui comprend : une cuve d’adsorption ; un compresseur d’air pour pomper de l’air dans la cuve d’adsorption ; une vanne pour purger la pression de la cuve d’adsorption ; un adsorbant disposé dans la cuve d’adsorption adsorbant un constituant non oxygène de l’air lorsque la cuve est mise sous pression, de façon à produire de l’air enrichi en oxygène, et désorbant le constituant non-oxygène lorsque la pression est purgée.
