Comparative Analysis: Oxygen Gas Generators vs. Oxygen Gas Cylinders

Oxygen generators are used in various industries, including production facilities and hospitals. Some industries that require oxygen supply include computer chip manufacturing, medical life support, glass blowing, and wastewater treatment. Having a steady supply of oxygen on hand is critical for ensuring proper functioning and production in these industries.

Oxygen can come from two main sources: generators and cylinders. It’s important to recognize the differences and how one can be more cost-effective and convenient than the other. In this article, we’ll compare the two sources of oxygen.

Understanding Oxygen Gas Generators

PSA generators use a molecular sieve to separate gas molecules. They remove the N2 from the air to produce oxygen. They constantly pressurize and depressurize two towers to produce a continuous supply of oxygen.

The key advantages of using oxygen generators over oxygen cylinders include:

  • Continuous oxygen production and reliability. These generators produce a continuous supply of oxygen without running out. They never need to be swapped out, unlike oxygen cylinders.
  • Environmentally friendly. Oxygen generators offer eco-friendly oxygen production that requires only a small energy supply to run. In addition, there are no trucks consuming fossil fuels needed for delivery.
  • Economical. Oxygen cylinders represent an ongoing cost for your business. Some businesses spend thousands on oxygen cylinders every year. Oxygen generators represent a small up-front cost, but once purchased, they require little energy to run

Understanding Oxygen Gas Cylinders

Oxygen cylinders come in different sizes and offer oxygen at a variety of purity levels. Although O2 cylinders require no power to function, they are only cost-effective for businesses that need only a small supply of oxygen throughout the year.

Comparative Analysis: Oxygen Cylinder vs. Generator

If your business relies on a steady supply of oxygen, consider the following variables when trying to decide between oxygen cylinders and generators.


The cost of running an oxygen generator is low compared to the cost of replenishing oxygen cylinders regularly. Oxygen cylinders can cost thousands annually. While costs vary, many businesses say their oxygen generator pays for itself within 6-18 months after purchase.

Supply and Capacity

Oxygen generators produce a continuous supply of oxygen without requiring the user to rely on an external supplier. A supply of oxygen cylinders is subject to supply chain problems, which can fail to meet the oxygen demand. In addition, consumers who order oxygen may also be subjected to ongoing changes in costs, making budgeting difficult. Oxygen generators, on the other hand, are always available, on-site, and ready to produce oxygen as needed.

Purity and Quality

Oxygen purity and quality vary depending on whether the customer is using an oxygen cylinder or generator. Oxygen generators produce oxygen at a purity level of up to 99%.

Safety and Risks

Oxygen cylinders can present a safety risk because high-pressure compressed gases can be hazardous. It’s important to train workers to handle oxygen cylinders properly to ensure job site safety.

Operational Flexibility

Oxygen cylinders can take up a lot of space. Depending on how many oxygen cylinders your business uses at one time and how many cylinders it continuously stores for pickup and replenishment, oxygen cylinders can use a lot of valuable floor space.

Oxygen generators are typically more compact and can meet the customer’s business needs without requiring this storage space.

Making the Right Choice

Deciding whether to use an oxygen generator or an oxygen cylinder can be a tough business decision. Some factors to consider:

  • Business size
  • Annual oxygen cylinder costs
  • Business commitment to eco-friendly practices
  • Budget

For many businesses, deciding whether to get an oxygen generator is easier after consulting with On Site Gas Systems. Our experts can discuss your custom system, including costs and specs.

Oxygen Generator Machines: How Businesses Benefit From O2 Generators


Oxygen generator machines are valuable for businesses in a variety of industries. Oxygen gas is vital in many functions in supporting life and essential chemical reactions. Whether you are looking to replace your oxygen supplier soon or are in the market for buying an oxygen generator, it’s good to educate yourself on the many benefits an oxygen generator system can have in the business sector. Let’s take a look.

Benefits of Oxygen Generator Machines Explained

Oxygen has sustained human life on earth for countless millennia. The essential gas is also helpful in hospitals, welding facilities, aerospace, and many other industries. Today’s oxygen generator systems are safer at regulating oxygen production than other current means of oxygen supply. Their notable applications include fish farms, welding, research labs, veterinaries, and medical life support. On Site Gas manufactures high-quality oxygen generators to provide oxygen when you need it during those critical times.

In welding and metalworking, oxygen increases the temperature of the welder’s flame, making it useful in the precise cutting of steel and other metal alloys. While it takes skill to operate an oxygen-powered flame, its uses are advantageous and sometimes required for specific applications. It also melts the metal in a more localized area than other types of gas could.

In zoos and aquariums, oxygen plays a vital role in aquarium keeping and veterinary medical life support for many animals as the need arises. The oxygen supply is available quickly and efficiently minimizing any risk to the animals.

Many research facilities use oxygen generators daily in their line of work, including biochemists, universities, government science departments, and more. Depending on the research being conducted, a generator in this setting needs to operate dependably to preserve a safe working environment.

In the gold and silver mining industries, using oxygen to convert mineral sulfides to sulfates and processing them, gold yield can be more than doubled over standard or gravity separation and concentration. Oxygen is safer and produces a higher yield, effectively lowering the liability and increasing profits simultaneously. High-purity oxygen gas can be delivered directly to the worksite via a portable oxygen generator machine.

Last but not least, oxygen is best known for providing life support in various medical applications. Therefore, an oxygen generator machine needs to deliver the gas consistently and be dependable. It is a vital tool for hospitals, in-patient services, hospices, urgent care facilities, and ambulances. Portable generators are particularly useful in these situations.

The POGS 33 Unit in Action: How Our Oxygen Generators Helped Save Lives During Samoa’s 2019 Measles Outbreak

On December 29th, 2019, the Samoan government lifted a six-week-long state of emergency that was put in place in response to a deadly measles outbreak. In fact, the epidemic was so severe that the government was forced to shut down all public services for two days in early December.
On Site Gas, in conjunction with one of our partners in Australia, worked to help stop the outbreak by deploying a portable oxygen generator system (POGS) through the Royal Australian Air Force (RAAF).
Read on to learn more about how our oxygen generators were used to combat this epidemic.

The Global Measles Resurgence

For decades, measles was widely believed to have been nearly eradicated across the globe. However, in the past few years, many industrialized nations and third world countries have seen a resurgence in the disease.
This highly contagious diseases, known for its rash of flat red spots, can lead to death without prompt and aggressive treatment. In fact, if left untreated, one out of 20 children will contract pneumonia, and one out of 1000 will develop encephalitis (also known as swelling of the brain). This complication often leads to convulsions, loss of hearing, developmental issues, and more.

Samoa’s Measles Epidemic

In early December, the Samoan government began marking unvaccinated households with red flags in an effort to control the measles outbreak, which would go on to infect 5,600 people (with 81 fatalities). On December 5th and 6th, the government shut down public services to focus all attention and resources on the epidemic. The shutdown was also part of a vaccination campaign, which provided immunizations for more than 58,000 people and pushed the country’s vaccination rates towards 95 percent.

Our POGS Unit’s Lifesaving Technology

The POGS 33 unit, an FDA-approved portable generator that delivers 30 liters of oxygen per minute, was deployed to Samoa to help combat the measles epidemic. The system’s primary function is to provide medical oxygen to remote locations and harsh environments. It’s self-contained, easily portable, and requires little to no maintenance, making it an effective tool for use during emergencies. Plus, the unit’s generators can be operated independently or in multiple combinations to provide unlimited oxygen as needed.
On Site Gas’ POGS 33 unit is ideal for field hospitals, as it requires just four people to carry it to its destination. Once set up, the system can be used to fill cylinders, operate medical equipment, and more. Our POGS units can be deployed quickly and easily, without the need for heavy equipment or liquid oxygen deliveries. This is essential for emergencies and other dire situations where time is of the essence.

On Site Gas: A Trusted Choice for Portable Oxygen Generators

Over the years, On Site Gas has built a reputation as a leading source for oxygen generators for a variety of applications. In fact, several US government agencies, including the Federal Emergency Management Agency (FEMA) and the Department of Homeland Security (DHS) have relied on our equipment for disaster relief and emergency preparedness.

Oxygen Generators for Disaster Relief


When disaster strikes, time is of the essence and preparation is key.  Preparation is started at the Federal, State and Local level.  Disaster Management Plans consist of a cache of medical equipment, including complete portable hospital tents that can be turned into field operated hospitals.  With these portable hospital tents oxygen is a major requirement.  On Site Gas Systems, Oxygen Generators have become a mainstay component of the field hospitals.  Having the ability to generate oxygen on site when needed eliminates the need to truck oxygen in assuming that oxygen is even available to be trucked in.  In many disasters there is no power to create oxygen in the traditional cryogenic manner and road access may be limited or non existant.
Keeping oxygen generators as part of an emergency management plan can help you stay safe during emergency situations. Investing in an oxygen generator system before disaster strikes will ensure that, in the event of an emergency, your oxygen supply will not be at risk.
What Emergencies Can You Use Oxygen Generators For?
You never know when a disaster situation will occur. In the event of an emergency, hospitals including field hospitals  will need to have access to oxygen in order to provide to their patients. Time is of the essence and waiting too long for oxygen delivery can mean the difference between life and death, assuming delivery is even avaliable.
On Site Gas offers many different oxygen generators for you and your company to use as a form of disaster preparation. You can use our oxygen generators to assist in multiple types of emergency relief, such as:

  • Epidemic outbreaks
  • Natural disasters such as earthquakes, landslides, hurricanes, and flooding
  • Accidental emergencies such as infrastructure collapse and equipment malfunction
  • Terrorism
  • Medical emergencies
  • Chemical and biological disasters

How Do Oxygen Generators Help During Disasters?
On-site oxygen generators can provide multiple benefits for disaster relief.

  • Instant Oxygen Supply – When disaster strikes, you may need oxygen immediately. Waiting for oxygen delivery is not an option. With on-site oxygen, you can receive the life-saving oxygen you need in a fraction of the waiting time.

Using Oxygen Generators for Water Treatment Systems

Clean, pure water is a fundamental human necessity. Whether it be for cooking, or hygiene, every person needs safe water. Clean water is becoming harder to obtain as our worldwide consumption of water continues to grow. By injecting oxygen into your water system it can increase the effectivity of removing contaminants and impurities from your water supply.

How do Oxygen Generators Work?

Oxygen generators allow you to produce your own oxygen when and where you need it (versus relying on a liquid oxygen supply or depending on filled cylinders). By using Pressure Swing Adsorption (PSA) to generate oxygen, nitrogen is separated from the oxygen that is in the regular air.
At On Site Gas Systems, our oxygen generators have a vessel that absorbs the nitrogen molecules, and while the oxygen molecules drift past that vessel, they collect into an oxygen receiver tank. The oxygen receiver tank is attached to the oxygen generator, then releasing the pressure from the vessel and venting the nitrogen molecules back into the atmosphere. This cycle repeats in a second vessel, providing a consistent flow of gas from our oxygen generators.

What Applications are There for Oxygen Generators?

There are various applications for oxygen generators in water treatment systems including:
Oxygen Generators for Ozone: Using an oxygen generator for ozone is beneficial in many different situations. It works by acting as feed gas for your ozone system. It is environmentally safe, which makes it suitable for treating vast quantities of water efficiently (including ensuring clean drinking water from the tap). A couple of examples of using oxygen generators for ozone include making suitable drinking water for animals, water for cleaning equipment, and replacing chloride with ozone in swimming pools.
Oxygen Generators for Waste Water: Waste water can come from many different sources – whether it be from an industrial building, work office, or someone’s home, it can come from anywhere. By injecting oxygen into your waste water it can significantly increase bacteriological survival and regeneration. Oxygen generation systems can provide years of self-contained oxygen production – meaning you won’t have to deal with the ongoing expense of delivered cryogenically produced oxygen. Oxygen generators for waste water are also very cost effective and low in energy use. At On Site Gas Systems we offer custom engineered oxygen generators, oxygen container systems (up to 99% purity), and oxygen generators (up to 95% purity).
At On Site Gas Systems, we are experts in oxygen generators. Whether you’re looking for one to help with waste water, or ozone, we have what you need for your water treatment systems. Our systems are designed to meet your specific purity, pressure, and flow requirement needs (and at a lower cost than delivered gas).

How Oxygen Is Used in Glassblowing

Glassblowing is a unique art that combines the skill of melting glass with the subtle blowing of air to form masterful decorations. However, in order to work properly, the flame that the glassblower uses must be a specific temperature. That’s where oxygen gas comes in. With the high purity of oxygen gas provided by our 95% O2 PSA on site oxygen generators, glassblowers can make sure their torches remain the proper temperature for their masterpiece.

How They Use It

As mentioned, glassblowers rely on oxygen as their fuel for the burners and torches they use to melt the glass. Basic compressed air just doesn’t produce the necessary heat. Oxygen is the only fuel source that will ensure the flame is hot enough to effectively and strategically melt quartz and borosilicate glass. In most situations, the glassblower will use oxygen gas at a range of 10-15 psi, with a purity of 95%.

Why Glassblowers Rely on Oxygen Generators

Instead of having to manage and maintain oxygen cylinders, many artists are choosing to implement the use of an on site oxygen generator. This is for many reasons:

  • It Is Dependable – Not all glassblowers work in urban areas, and getting cylinders delivered is not reliable. With on site oxygen generation, there is no risk of running out of gas, so operations won’t have to come to a halt.
  • It Is Affordable – Oxygen cylinders can get expensive, and they are a recurring cost that doesn’t go away. On the contrary, with on site oxygen generation, glassblowers only have the upfront costs to worry about. Once those have been recouped, the artist can continue producing oxygen for essentially no additional costs.
  • Is It Safe – The art of glassblowing is dangerous enough, the last thing a glassblower needs to worry about is a high-pressure cylinder exploding and damaging something in the shop.
  • It Is Durable – Our on site oxygen generators are made to handle the most rugged environments, so wherever the glassblowing is being performed, the oxygen generator will stand the test of time.

Glassblowing is a meticulous art, and every detail matters. With the use of on site oxygen gas generator, a glassblower can be sure that the flame they are using stays at a high enough temperature to get them the results they need. The last thing they want to do is start all over because the flame isn’t hot enough. If you are in the glassblowing industry and you want to learn more about the true ROI of an on site oxygen generator, please contact us today. We would love to discuss the options available to you.

On Site Oxygen Use in Vet Clinics

With National Dog Day right around the corner (August 26th), there is no better time than now to discuss why veterinarians need an onsite oxygen generation system. A 95% pure oxygen gas is used on animals both during and after any type of surgical procedure. It helps to keep the animal stable until they can effectively breathe for themselves. In a typical situation, the on site oxygen generator is installed outside of the vet clinic or hospital, with feed lines going in to each of the operating rooms, so it does not take up the minimal space in most surgery rooms. On site oxygen generation can be used effectively for both large and small veterinary clinics.

Why On Site Oxygen for Vets

Just like other medical facilities, veterinarians need to be able to rely on their oxygen supply. It is impossible to predict how much oxygen will be required, and if the supply runs out, the pets’ lives are at risk. As such, it is evident why many vet clinics make the switch from oxygen cylinders to on site oxygen generation.

  • By producing their own oxygen, the veterinarian never has to worry about running out.
  • It is way more convenient to simply set up the oxygen generator and forget about it than it is to monitor oxygen tank levels and arrange for pick-ups and deliveries.
  • Over time, on site oxygen generation is also much more cost effective, as it only has to be paid for upfront, and has minimal maintenance fees over time. There are no recurring charges to deal with, other than minimal routine maintenance costs.

On Site Oxygen Options for Vets

At On Site Gas Systems, we carry all types oxygen generators for any application. This includes:

  • Customized oxygen generation designed for the specific needs of the vet.
  • Filling stations that can be used at either 93%, 95%, or 99% purity, allowing the vet to fill their own cylinders as needed for a fraction of the cost.

No matter how much oxygen gas a veterinarian requires, they can depend on our on site oxygen generation to provide it. For over 25 years, On Site Gas Systems has been engineering custom and off-the-shelf oxygen generation solutions for veterinarians in both rural and urban areas. To learn more about how on site oxygen for vets can benefit you, contact us today, and always have the oxygen you need no matter what animal emergency comes your way.

Why the Military Relies on Portable Oxygen Generators

[vc_row][vc_column][vc_column_text]Every moment of every day, U.S. soldiers are risking their lives for our country, and more times than not, they are in extremely remote locations surrounded by rugged conditions. So, when medical care is needed, they need an oxygen generator that can withstand the harsh conditions without being too bulky to transport. With our portable oxygen generator systems, referred to as POGS, the military can receive the on-demand oxygen they require to provide medical care to our soldiers across the globe.

Examples of On Site Oxygen Uses

Our USP 93% POGS were built with the brutal environment of a war zone in mind. Meaning they are very well made and durable, yet they are small and simple to transport to remote locations. Most importantly, they create pure, medical-grade oxygen to aid our soldiers wherever it is needed. Here are just some of the ways the military uses our portable oxygen generator systems:

  • POGS are used to fill up cylinders that can be transported by first responders. As they arrive on the scene, they have full tanks ready to go, and the tanks can be easily refilled as needed.
  • Alternatively, POGS are used directly on a patient in a field hospital instead of having to worry about filling up cylinders. The portable oxygen generator system makes sure the patient never runs out of the oxygen supply they need to survive.
  • Our medical-grade on site oxygen generators are also used on military aircrafts to provide the necessary oxygen for ventilators and anesthesia units.
  • On site oxygen is also being used to provide hyperbaric oxygen therapy to patients, which has been shown to be an effective treatment for PTSD and Traumatic Brain Injury (TBI).

Why On Site Gas Systems for POGS

When it comes to on site oxygen use in the military, it is impossible to predict how much is going to be needed. That is what makes on-demand oxygen so important. The military will always have the supply they need, no matter how many patients end up requiring the assistance of oxygen. With our POGS, they don’t have to worry about durability or transportability, as our units offer both. Not only are our portable oxygen generator systems functional, they are extremely effective at producing the purity of oxygen required for medical use. In fact, they are FDA approved as a Class II medical device, so doctors and patients can rely on their purity.
The military risks their lives every day, and with the help of POGS from On Site Gas Systems, many of these lives can be saved, even in the most extreme conditions.

At On Site Gas, the process of the Pressure Swing Adsorption (PSA) Technology is an extremely clean operation. The only ‘raw material’ is air. On-site generators allow for an uninterrupted supply of gas with a high purity output. This means that you can produce gas where and when you need it, and in the exact quantity and quality you need.Any business that uses more than one cylinder of nitrogen or oxygen a week should consider an on-site nitrogen or oxygen generator. On Site Gas Systems provides generators to businesses all over the world. These systems are not only more convenient than bulk delivery; they can pay for themselves in less than 12 to 15 months.

Custom-Designed, On-Site Oxygen Generators

On Site Gas System’s generators are custom-designed to meet the needs of each client. Generator sizes range from 2 SCFH to 75,000+ SCFH depending on the gas and purity requirement.

A Cost-Effective Solution

This ability to generate nitrogen or oxygen on-site offers businesses considerable savings because it eliminates the need to purchase bulk gas and have it delivered.

Convenience With Pressure Swing Adsorption (PSA) Technology

When one of On Site Gas System’s generators is connected to a business’ air supply (air compressor systems are available), the business has the ability to produce an unlimited supply of nitrogen or oxygen. This is possible through the use of Pressure Swing Adsorption Technology. The use of PSA provides businesses with the convenience of on-demand gas production, thus, essentially eliminating the wait times commonly associated with bulk delivery.

How Pressure Swing Adsorption Works

The air that surrounds us contains roughly 78 percent nitrogen, 21 percent oxygen and 0.9 percent argon (with the remaining balance consisting of other gases): pressure swing adsorption (PSA) technology is designed to separate the nitrogen or oxygen from the rest of the air. This process is possible due to Carbon Molecular Sieve (Nitrogen) or Zeolite (Oxygen). Carbon Molecular Sieve at high pressures, attracts (adsorbs) oxygen, while letting the nitrogen flow to the receiving tank. Zeolite performs the same function with oxygen molecules in our oxygen generators This is the key process behind the best nitrogen and oxygen generators.

The Process of Generation Via PSA

On Site Gas System’s nitrogen and oxygen generator systems consist of two beds: Each bed contains an adsorbing sieve material:

  1. As the high pressure air enters the first tank, it moves through the sieve, and the oxygen or nitrogen is adsorbed depending on the generator type and output gas required.
  2. The process gas is then channeled to a buffer or storage tank.
  3. Directly before the first bed is completely saturated, the feed air is redirected to move through to the second bed, where the same process occurs.
  4. Once that process is complete, the first oxygen or nitrogen generator bed is vented out to the atmosphere, allowing the waste gas to release from the sieve.
  5. Completing regeneration of the first bed requires purging it with a small amount of process gas.
  6. This entire process continues in the oxygen or nitrogen generator until the business’s demand for process gas is met.

The Life of the Carbon Molecular or Zeolite Sieve

Under typical operating conditions (i.e., clean, dry feed air supply), a Carbon Molecular or Zeolite sieve lasts indefinitely.

Productivity of a Pressure Swing Adsorption O2 Generator

The purity of the nitrogen or oxygen gas a business needs affects the productivity of a pressure swing adsorption (PSA). With a fairly small increase in the amount of feed air moving through the sieve, a Pressure Swing Adsorption Generator can produce substantially more process at 95 percent purity than it can at 99.9 percent+.
