The capacity of the PSA (Pressure Swing Adsorption) oxygen machine is determined according to actual needs and can be selected according to the user's gas consumption.

PSA oxygen concentrators usually provide capacities ranging from a few liters per minute to several thousand liters per minute. Large industrial PSA oxygen concentrators can provide higher capacities and are suitable for industrial production and medical purposes. Small home or portable PSA oxygen concentrators usually have lower capacities and are suitable for daily home use or oxygen therapy needs while traveling.

It should be noted that the capacity of the PSA oxygen concentrator has a certain relationship with the size and power of the equipment. Generally speaking, the larger the capacity of the PSA oxygen concentrator, the size and power of the equipment will increase accordingly. Therefore, when choosing a suitable PSA oxygen concentrator, factors such as oxygen consumption, budget, and usage scenarios need to be comprehensively considered.
