VPSA vs. PSA Oxygen Concentrators

VPSA vs. PSA Oxygen Concentrators

If you need a machine to make oxygen, you might hear about PSA and VPSA types. Both pull oxygen from the air, but a VPSA oxygen concentrator is the more advanced and efficient model. Knowing the difference helps you choose the best one for your needs.

Differences in Technology
PSA oxygen generators use pressure changes to work. VPSA adds a vacuum pump during the release step. This helps the material clean itself better and produce more oxygen.

Differences in Process
In PSA, air is pushed in at high pressure and released at normal pressure. In VPSA, air goes in at lower pressure and a vacuum pump helps pull out the oxygen.

Differences in Energy Use
PSA systems mainly use an air compressor. VPSA systems add a vacuum pump but work more efficiently. This can make the whole system use less energy.

Because of this, VPSA oxygen generators work faster, more efficiently, and more steadily.

The lower adsorption pressure and vacuum desorption of VPSA reduce wear on oxygen concentrator components and extend the product life. This amazing durability means companies can offer a longer warranty, which helps save time and money on repairs.

When you look at performance, the VPSA oxygen concentrator is very strong.  Its oxygen output pressure reaches 70kPa. This high pressure makes it perfectly compatible with ventilators and other medical equipment. At the same time, it runs very quietly, with a quiet noise down to 27.3dB. This makes for a much calmer environment.

AERTI new arrival VPSA oxygen concentrator often comes with extra features for patient care. Many have a built-in blood oxygen measurement port. They also often include a nebulizer function for atomization therapy. These features make one machine do the job of several.

Inside, a strong four-cylinder, powerful oxygen supply system ensures you get a steady, non-stop flow of oxygen. This reliable build, plus the gentler operation, leads directly to lower maintenance. You will spend less time and money on servicing the machine. It's very good for distributors who usually rent the machine to patients.

In short, the VPSA oxygen concentrator is a major upgrade. Its use of a vacuum makes it more efficient, quieter, and much tougher than old-style PSA models. For anyone who needs a reliable and durable oxygen source with a long life-span, the VPSA oxygen concentrator is the clear and smart choice.
