Big sale XNUO S35 olive oxygen concentrator 20liter 20lpm generator medical psa 20L oxygen-concentrator

Material of molecular sieve The use of lithium low silicon oxygen molecular sieve (oxygen purity 93%±2) has the advantages of high oxygen purity, high production rate, small mechanical wear and long life. Service life After 6,000 hours of use, the oxygen purity decays to 85%±3. After 12,000 hours of use, the oxygen purity decays to 80%±3. After 20,000 hours of use, the oxygen purity decays to 70%+3. When the oxygen concentration is not enough for use, it is required Replace the internal molecular sieve.
