The ON2 VPSA system works by separating Nitrogen (and other trace gases) from the air with a Molecular sieve. Resulting in Oxygen purities of 93% or greater. ON2 chose VPSA as the mechanism of choice because of the cost benefits to the customer over the life of the concentrator. These include much lower power usage, shorter start cycle, and continuous supply.

ON2 Oxygen Concentrators start and stop with demand resulting in cost savings on electricity. Oxygen purities in excess of 95% are consistently achieved. ON2 Oxygen Concentrators have minimal breakdowns due to the quality of components used. ON2 provides excellent service and 24/7 telephone support.

75 to 85 psi which allows for the accumulation of oxygen in the storage tank providing a buffer during short power outages, or short maintenances.

Yes, if you add an ON2 Cylinder Filling Station. This system can be installed in the same area as the OC, or remote from this location as long as piping can reach that location.

Yes, cylinders much be vacuumed to 24 inhg before they are filled. This is per CSA regulations on medical gas systems. All ON2 Filling Stations come with a vacuum pump as part of the Standard package.

With an ON2 Cylinder Filling Station you will save on shipping costs and cylinder rental, and utilize Oxygen production of your ON2 Oxygen Concentrator during lower demand times in the facility; thereby severing your dependency on medical gas supply companies. You can also fill cylinders for surrounding facilities (Clinics, Vet Clinics, Home Care cylinders) as a revenue generating plan for your facility.

As long as you can supply the filling station with oxygen from your ON2 Oxygen Concentrator location, it can be remote. ON2 offers Remote Cylinder Filling Stations for facilities with space constraints. As long as there is a footprint outside the hospital of approximately 8’x20’ we can install a Remote Cylinder Filling System (RCFS) at your site.

Yes, if it is exposed to water droplets or humid air. The typical life span of Molecular sieve is 100,000 running hours, if kept dry. ON2 uses Gold Seal Standard air compressors and filters to maximize the life of the sieve medium, to keep customer long term costs to a minimum.

Typically, 10-15 years with ON2 air compressors and filters in place.

No, this should be done by a trained ON2 Technician as the dust is problematic, and if not installed properly your ON2 OC will not operate at peak efficiency.

No, there are several different manufacturers and grades of Molecular sieve. ON2 provides a Gold Seal Standard product from the USA.

While your ON2 OC will produce dependable oxygen 24/7, there are limitations to its operating environment, and there can be times when additional equipment is required. ON2 can provide an air dryer if needed, especially in more humid climates to prevent moisture from getting to the molecular sieve and destroying it. We want maximum longevity for our customers, so in some instances we will recommend this equipment as a needed addition to the system.

Yes, as long as the dryer meets the OC’s cfm requirement. ON2 can provide a quote for these units if needed, either during initial installation, or after the fact, if environmental conditions have changed.

Depends entirely on the size of the system. ON2 systems have among the lowest power usage statistics in the market, and during the quoting process we will give you our best estimate on electricity usage and costs depending on your location.

Yes, we have a Preventative Maintenance Program (PMP). ON2 is willing and able to supply the new customer with a PMP that best fits their needs, from scheduled maintenance to a full extended warranty. Existing customers can sign up at any time for the scheduled maintenance program, which allows the hospital to better budget it’s maintenance costs.

ON2’s OC Systems vary in size significantly. The average hospital can expect to see approximately $8000 a year in costs including parts, labour and travel costs, but larger facilities can be as high as $50,000.

Yes, ON2 provides exemplary 24/7 phone support. Our ON2 technicians have over 40 years of combined knowledge and experience in maintaining and troubleshooting our equipment. They are able to get most customers back online during a typical Troubleshooting call. In some instances, travel to the site is necessary, but this is a rare event.

Our ON2 technicians can do everything from installation of electrical and gas connections, to commissioning and testing of the unit if it was installed by others. We are willing and able to provide full service installation if the customer so desires.

One of the primary benefits of ON2’s Oxygen Concentrator is that it allows the facility to break free of their dependency on the gas supply companies and their tiered costing. ON2 Concentrators provide on-site Oxygen on demand, 24 hours/day and 365 days/year. Our reliable and cost effective SOLUTION allows you to provide for the needs of the hospital at all times, without concern for delivery logistical issues that can arise when your gas supply is some distance from your facility.

ON2 works with the customer to fully understand their needs both on average demand as well as peak average demand to properly size the system. If the facility is remote, we will also suggest a duplex system for even greater peace of mind.

ON2 provides a Remote Oxygen Concentrator System (ROCS) that allows any hospital with the ability to add an ON2 OC system to supply worry free oxygen without giving up valuable space in a likely already crowded building.

Oxygen Concentrators vary in size; typically, system will fit in a 10’ x 12’ room. We custom build configurations to fit the smallest of clinics up to multi-thousand bed major facilities worldwide. By duplexing and triplexing our largest units we can supply to any and all hospitals providing significant reliability and flexibility.

ON2 can provide any configuration that works for the facility up to and including housing the compressor(s) in a ROCS unit while the OC is housed in the building itself.

Yes, ON2 provides an analysis as part of the initial consultation that addresses the fact that at higher altitudes, larger systems may be required.

-40 to -65 dew point. This exceeds both the CSA and ISO Standards for medical gases, which ON2 strives for in all specifications.

ON2’s system can start and stop with demand and be online and producing oxygen with a 3-minute start-up. Our dual stack system allows for a continuous feed of Oxygen to the facility, lowering the pressure swings typically seen in single stack systems. The mix tank allows for a solid 95% purity to always be flowing to the oxygen storage tank as well.

Yes, ON2 systems start and stop automatically, and have an automatic optimize function. As well we use Gold Seal Standard oxygen analyzers to ensure the purity of gas to your facility is maintained at all times.

ON2 has done extensive research into the topic of Oxygen vs. Oxygen 93, and every report or paper published to date shows no discernible difference between gases as to the physiological effect on any patient. All patients respond to and heal identically regardless of the gas used.

90% to 95.4% Typically > 95.0%. ON2 uses oxygen analyzers to verify the continual production of gas by our concentrators and the normal feed to the facility is 95% or higher, but the CSA and ISO Standard does allow dips to 90%. Our units are designed to shutdown and alarm at below 90% purity, as this would be an anomaly.

2 top quality ON2 Oxygen Analyzers. These units are the Gold Seal Standard for oxygen analyzers in the world, and are robust and reliable like no other. We have units that are still working after 29 years, and during testing and calibration are still accurate to or above the devices specification.

Typically, 20 plus years, although ON2 has Concentrators in service that were installed over 38 years ago. Most of the wearing components (Compressor, Vacuum pump) have been replaced, but the unit continues to provide the facility in question with reliable and dependable oxygen to this day.

A properly sized ON2 Concentrator System can use as little as 160kWh of electricity in any given day to provide for all of the oxygen needs for that facility.

No, unlike the bulk storage facilities, the ON2 Oxygen is produced on demand and does not evaporate. It is stored in a gaseous form, and is produced on demand. If the facility isn’t using oxygen, the unit shuts down until needed.

The ON2 Oxygen Concentrator produces oxygen on demand with no evaporation to worry about. The ON2 systems are inflation proof, pandemic proof (liquid O2 needs to be delivered) and dependant on nothing but a supply of electricity to produce continuous oxygen for your facility.

Yes, the ON2 system needs to be in a +5 to +50 degree Celsius environment. In many cases this can be accomplished by proper ventilation, but in some cases climate control is necessary.

Yes, ON2 has a number of leasing options available to the prospective buyer, to make the upfront capital expenditure less of a budgetary issue.

ON2 provide Oxygen Concentrators to the industrial and commercial marketplace with cost effective, dependable and reliable solutions for their medical grade oxygen needs. Fish Farms, Vet Clinics, Hydroponic farms, Waste Management, Composting are but a few of the industries that can benefit from an ON2 Oxygen Concentrator.

Yes, ON2’s systems use a minimal amount of electricity and provide an extremely efficient means to produce medical grade oxygen. On-site gas also alleviates the harmful emissions associated with transportation of bulk gas suppliers.

At ON2 we perform a 1 week in house “Free run” that simulates the actual demands a system will see in the field. All alarms and settings are also verified at this time. This allows us to work through any possible “bugs” before your system is shipped. As well the unit is tested in accordance and witnessed by the Manitoba Inspection and Technical Services department. The final check is a CSA electrical inspection to certify that the unit meets all of the Canadian electrical safety standards.

All ON2 Oxygen Concentrators used in facilities with any kind of patient care use the Paramagnetic Oxygen Analyzers. Vet Clinics and industrial applications use an Oxygen Purity Indicator instead of an analyzer to determine the oxygen content produced.
