What is Oxygen Generator?

Oxygen generators are designed to produce purified oxygen from ambient air, supplying continuous flow oxygen gas. The oxygen produced has a purity level of up to 95% or more, depending on the application’s requirements. In simple terms, oxygen generator machines utilize air compression and filtration processes to produce oxygen, which can be used in various applications ranging from medical treatments to industrial processes.

Oxygen generators come in various sizes, from compact portable units to large-scale industrial systems capable of producing thousands of liters of oxygen per minute.

Types of Oxygen Generators

There are four different types of oxygen generators available on the market, each with its own unique advantages and disadvantages.

• Pressure Swing Adsorption (PSA) Oxygen Generators

PSA oxygen generators are one of the most commonly used types of oxygen generator machines. They use a process of adsorption and desorption of gases through a bed of zeolite or other adsorbent material to separate oxygen from other gases. PSA generators typically consist of two adsorption vessels filled with zeolite, which alternate between adsorption and desorption cycles to produce oxygen.

PSA generators are commonly used in medical and industrial applications because they are reliable and efficient. They can produce oxygen with a purity of up to 95%, making them suitable for medical use. PSA generators also have a low operating cost, making them a cost-effective alternative to traditional oxygen cylinders.

• Vacuum Pressure Swing Adsorption(VPSA) Oxygen Generators

Vacuum Pressure Swing Adsorption(VPSA) is a process that is similar to PSA, but it operates at a lower pressure. It’s a cost-effective solution for generating oxygen for industrial applications.

The VPSA process uses molecular sieves to selectively adsorb nitrogen and other trace gases from the air, leaving behind a stream of highly concentrated oxygen. This oxygen can be used in various industries, such as metal fabrication, paper and pulp production, wastewater treatment facilities, medical facilities, and food packaging.

One of the significant benefits of using VPSA Oxygen Generators is their high-efficiency levels. These generators have up to 95% recovery rates with low energy consumption levels compared to traditional cryogenic systems that use high amounts of electricity. Moreover, they provide a continuous oxygen supply with minimum downtime and maintenance requirements.

Additionally, these generators are easy to install and operate without requiring skilled personnel. They come in different sizes that can be customized based on the specific needs of the user. That means you can get a generator that fits your space constraints while meeting your required flow rate demand. In summary, VPSA Oxygen Generator machines offer an efficient and cost-effective way of producing pure oxygen on-site without compromising quality or reliability.

• Membrane Oxygen Generators

Membrane oxygen generators use permeable membranes to separate oxygen from other gases. These membranes have small pores that allow oxygen to pass through while blocking other gases. The gas mixture is passed through a series of these membranes, and the oxygen is separated from the other gases.

Membrane oxygen generators are typically smaller and less expensive than PSA oxygen generator machines. They can produce oxygen with a purity of only 40%, which is suitable for some industrial applications. However, membrane oxygen generators are not suitable for medical use because they cannot produce oxygen with the required level of purity. This method is primarily used in small-scale applications, such as home oxygen generators, and vehicle oxygen generators.

• Cryogenic Oxygen Generators

Cryogenic oxygen generators use a process of liquefaction and distillation to separate oxygen from other gases. The air is cooled to a very low temperature, causing it to liquefy. The liquid air is then separated into its components using distillation, with the oxygen being collected and stored in a tank.

Cryogenic oxygen generators are typically used in large-scale industrial applications because they can produce large quantities of oxygen. However, they are expensive to operate and maintain, and they require a large amount of space.

Benefits of Oxygen Generators

One of the primary benefits of an oxygen generator is cost savings. With an oxygen generator, there is no need to purchase or refill traditional compressed oxygen gas cylinders, which can be expensive and time-consuming.

In addition to cost savings, using an oxygen machine generator provides greater flexibility in terms of where and when you can access a supply of oxygen. This is particularly useful in remote or hard-to-reach locations where it may be difficult or impossible to transport traditional compressed gas cylinders.

Lastly, an oxygen generator machine offers a more environmentally friendly solution than traditional compressed gas cylinders as it reduces carbon emissions associated with transportation and production. Additionally, by eliminating the need for cylinder handling and storage, there is a reduced risk of accidents related to handling combustible gases. Overall, the benefits of using an oxygen generator are numerous and diverse, making it a valuable investment for many industries.

What is an oxygen generator?

An oxygen generator consists of two tanks filled with a sieve, which provides a concentration of 93% oxygen for all your on-site equipment that uses 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 variations are 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 90 PSI, 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). Still, we recommend keeping an oxygen tank on hand in case of an emergency or an extended period 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 expect to enlarge your clinic, or do you soon plan to buy another anesthesia machine, oxygen cage or incubator? Since the oxygen generator has a long life expectancy, it is essential 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 from six months to two 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 therapy, Hyperbaric Oxygen Therapy, in veterinary medicine (HBOT). 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.

*Contact us to get an estimate of the payback of an oxygen generator in your clinic.

What is 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 about 15 years.

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