What is an oxygen generator?

An oxygen generator consists of 2 tanks filled with sieve which provides oxygen for all your on-site equipment that use oxygen. The oxygen generator uses the Pressure Swing Adsorption (PSA) technology to create oxygen. During this process, oxygen is separated from the components in the air.


Concentrator and generator, are they the same thing?

No, there is a lot of confusion as to the difference between a concentrator and a generator, but the differences are very important to take in consideration in a veterinary clinic. A concentrator is a small medical system for personal use which is less expensive than a generator. However, a concentrator can’t be used in a veterinary clinic because it does not have enough power to provide the necessary oxygen to the equipment. Contrary to a concentrator, a generator produces oxygen, which allows you to use the flush of your anesthesia machine. Another advantage of the generator is the reservoir which will continue to give you oxygen during a power failure (the size of the reservoir varies with the different models). However, we still recommend keeping oxygen cylinder on hand in case of an emergency or an extended period of time without electricity.


Identify your needs:

To better analyze your oxygen use, try to visualize your clinic’s future needs and not your actual oxygen use. For example, do you plan to move, do you plan to enlarge your clinic, or do you plan to buy another anesthesia machine, oxygen cage or incubator in the near future? Since the oxygen generator has a long life expectancy, it is very important to plan your purchase with the needs of your clinic in mind.

Although it is rare that all of your equipment is in use at the same time, you should identify your maximum need of oxygen at any given time. This way, you will make sure your oxygen generator will supply enough oxygen in case of an emergency or during busy periods.


  1. How many anesthesia machines do you have?
  2. Do you use oxygen cages and/or incubators?
  3. Do you use a respiratory ventilator?


You can refer to the table below to enter your answers. The total will indicate your average oxygen use.

Why would an oxygen generator be useful in my clinic?

The main advantage of having an oxygen generator is the savings of up to 80% of your actual oxygen expenses. Generally, we count the payback of a generator between 6 months to 2 years depending on the model and your oxygen use*. Having an oxygen generator in your clinic will avoid dependence on the delivery of cylinder oxygen. These systems will also permit you to provide the newest oxygenation therapy in veterinary medicine. It also eliminates the danger of having liquid oxygen at the facility (LOX). In addition to this, an oxygen generator is a great contribution to the environment since there are no related CO2 emissions.

What are the lifespan and what maintenance is needed for an oxygen generator?

We can estimate the lifespan of the compressor between 10 000 and 20 000 hours of use and the lifespan of the sieve up 15 years.

There is not much maintenance needed on these oxygen generators. We recommend changing the filters every 6 months. To make the generator work properly you need to make air changes in the room where the system is installed. The quantity of air changes per hour will vary on the size of your generator and the size of the room.
