Technical Questions
How does PSA work?
What is Pressure Swing Adsorption (PSA) Technology?
Does the equipment have to be air conditioned?
Does the equipment room require humidity control?
What are the maintenance requirements of PSA oxygen generators?
Can the air preparation equipment be located in a separate area from the oxygen generator?
Can the oxygen generator be operated with contaminated sieve, and what are the consequences?
How long does the molecular sieve last?
Is it easy to replace the molecular sieve and how much does it cost?
Can I use a regular compressor, or do I need an oil-free compressor?
Is all zeolite molecular sieve the same?
Do oil-free compressors cost more than regular compressors?
Can any air compressor be used with NOVAIR PSA O2 generators?
Do I need a dryer for the air preparation?
Product Details
What happens if the air compressor malfunctions and oil is introduced into the air line?
Do you need a desiccant dryer for the air prep or can I use a standard refrigeration dryer?
Can I use a desiccant dryer if I want, and are there any advantages or disadvantages?
Do you size systems differently for different altitudes?
What is the purity of oxygen produced by PSA?
What is the dew point of the oxygen produced by PSA?
Do different models of oxygen generators produce oxygen at different pressure levels?
What is the standard pressure of oxygen pressure produced by PSA?
Can you increase the pressure to a higher level?
Can you provide 7 or 8 Bar pressure?
Liquid oxygen has purity of 99% . . . is that better than 93% oxygen?
If the standard purity of PSA oxygen is 93% +-3%, can I stake steps to produce oxygen at the higher end of range, for instance 95%?
Why do some countries specify 99%?
Process FAQ's
What is the difference between an oxygen concentrator and an oxygen generator?
If millions of people, world-wide, use oxygen concentrators that produce 93% oxygen on a daily basis, why do some countries still specify 99% oxygen hospital supply systems?
Liquid oxygen has losses where a certain amount is lost to evaporation. Does PSA gaseous oxygen have the same problem?
Are there recommendations for a typical hospital oxygen supply system?
Can I monitor my oxygen generator system from a remote location?
How do I size a hospital PSA oxygen system?
What are some of the benefits of a PSA oxygen system compared to using cylinders or liquid oxygen?
Are there concerns about carbon monoxide and carbon dioxide when producing gaseous oxygen using PSA technology?
Is there equipment available that would allow NOVAIR to diagnose an oxygen generator problem from the factory in New York without having to travel to the job site?
Can an oxygen cylinder get contaminated?
How long does an oxygen cylinder last and does it have to be re-certified on a periodic basis?
Do I need to use a vacuum pump to empty a cylinder before re-filling?
Why are carbon filters used to produce medical grade oxygen?
Pricing FAQ's
What is the most cost-effective oxygen cylinder filling plant?
Why do several models of cylinder plants cost almost the same, but produce very different amounts of oxygen?
Can I reduce the cost of my system and just use an oxygen monitor?
How do carbon monoxide, carbon dioxide, and oxygen monitors work? Do they wear out?
If I sell or rent oxygen cylinders, how many cylinders do I need?
Are there different valves used on cylinders?
What equipment do I need to transfill a small cylinder from a large cylinder?
How much does it cost to fill a cylinder of oxygen using PSA oxygen?
How much energy does it take to run just a PSA oxygen generator?
Does NOVAIR test every oxygen generator before shipping to the job site?
How big is a PSA oxygen generator system?
Can I mount a PSA oxygen generator system on a skid?
