The present invention provides automatic regulating of oxygen and nitrogen concentration to firefighters, water sports workers and workers who work, general industry or those who need respiratory air for medical purposes, as well as a perfume supplying air containing fragrance And an oxygen and nitrogen concentration-regulated high-pressure air charger equipped with a generating means. The present invention relates to a membrane type oxygen and nitrogen separator, a multi-stage compression type high pressure compressor operating with a single driving force, an oxygen or nitrogen gas separator for separating oxygen and nitrogen for use in various fields and applications such as firefighters, skin scuba, Pressure air charger adopting a new function integrated high-pressure air charger adopting the control method which can adjust the concentration of the oxygen concentration in the range of 20 to 90% by volume. By this, it is possible to appropriately regulate and supply the concentration of oxygen or nitrogen required by the user or the user, It is possible to greatly reduce the scale of the facility and to save energy by using one driving force and to provide the high-pressure air purifying unit for filtering moisture and harmful gas contained in the compressed air, And a new aroma such that a perfume mixed with oxygen or nitrogen can be supplied, By providing the delivery system, it is possible to supply the respiratory air with oxygen or nitrogen appropriately regulated, and to provide oxygen and nitrogen concentration-regulated high-pressure air with a perfume generating means capable of providing freshness and comfort during breathing by addition of fragrance such as peppermint or aroma Air charger.본 발명은 소방관, 수중 스포츠 및 작업을 하는 작업자, 일반 산업용이나 의료용 목적으로 호흡용 공기를 필요로 하는 사람들에게 산소 및 질소 농도를 자동으로 조절하여 공급함과 더불어 향기가 포함되어 있는 공기를 공급하는 향기 발생수단을 갖춘 산소 및 질소 농도조절형 고압 공기 충전기에 관한 것이다. 본 발명은 소방관이나 스킨스쿠버, 또는 의료용이나 산업용 등 다양한 분야 및 용도로 사용하기 위한 산소와 질소의 분리 시, 멤브레인 방식의 산소와 질소 분리기, 단일 구동력으로 작동
