High purity oxygen, medical oxygen in line with national standards and convenient operation, oxygen agent, non-toxic, non-corrosive, oxygen safer agents ready to use oxygen preparation device built-in humidifier according to the instructions in order to regulate the flow of oxygen-free agent ratio noise according to their own economic strength to buy a suitable oxygen machine. After the selection of the appropriate function to find out the individual needs of the highest individual product price. 2 optional oxygen / oxygen machine should also be considered when the size, shape size, etc. vary oxygen machine, but the choice of home oxygen machine must have good heat dissipation, so as to ensure a long oxygen machine a state of operation. Cooling good oxygen machine, able to provide a stable oxygen concentration. 3 oxygen capacity must be stronger. When medical oxygen content of the standard 90% oxygen as the standard. Although home oxygen machine may not reach this value, but not too low, usually around 85%. So we have to choose when purchasing work noise machine, generally not more than 45 db, and only in this range is good. 4 Select the compressor displacement is large enough (3.8-4.2m3 / h) oxygen machine, otherwise easy to wear long run, lead to gas shortages and oxygen concentration decay. Leather wrist compressor is very important, it is best to use imported parts. Some users prefer to shape small oxygen machine, in fact, this model does not fit the larger compressor is limited by the performance naturally. Only close to the square of larger models, just big enough for a large compressor. Welcome to contact us!
