40 SCFH oxygen production at 50 PSI of delivery pressure. Nominal 90-93% oxygen purity.

The TOX-40MP is provided with built-in air compressors and requires only electrical power for operation.

Note: Standard power configuration is a L14-20P cord end for a 220v with neutral.  This will automatically be used if not stated otherwise in the electrical power options below:

The TOX-40MP oxygen concentrator provides oxygen pressures of 50 PSI continuously at an oxygen flow of 40 SCFH with a nominal oxygen purity of > 90%.

The TOX-40 MP is a turnkey unit with a built-in air compressor, boost compressor, and necessary buffer tanks to produce 40 SCFH of oxygen and boost to 50 PSI of delivery pressure for downstream applications.




The TOX-40MP is built to provide thousands of hours of continuous, reliable service.  Compressed air is filtered and cooled with an auto drain system to remove condensed moisture from the compressed air system.  This ensures longer life for the zeolite sieve material in the unit.  



The greatest advantage of the TOX-40MP is the entire unit is rebuildable.  This unit will serve you for many years with only minimal maintenance.  The sieve beds are replaceable, or rebuildable, valves can be cleaned or replaced.  The TOX-40MP will serve in your application for as long as you choose to maintain it.

We offer each replacement part for the TOX-40MP, and keep each in stock.  



Oil-less air compressors are used to provide compressed air for the oxygen concentrator sieve beds and boost oxygen to 50 PSI.  These compressors run efficiently and consume less power than industrial oxygen concentrators that require 90 PSI of incoming air pressure for operation.

Due to the fact the TOX-40MP can be rebuilt or repaired this unit will never be completely replaced with new.  This saves costs long-term versus alternative models that cannot be rebuilt and are replaced when parts are worn or zeolite requires replacement.  The TOX-40MP is a very economical oxygen generator to operate over the long term.


Made in the USA:

The TOX-40 is manufactured, assembled, and tested entirely in the USA.  


Compressed Air:

The TOX-40MP can be equipped with internal air compressors.  Small oil-less compressors are provided to provide compressed air required for oxygen production.  Two small 1/3 hp compressors are provided.  Compressors are reliable and require a rebuild after 8,000 hours of operation.   A final boost compressor is used to boost oxygen pressures from the standard 20 PSI to 50 PSI for higher pressure applications.

The internal compressed air option also includes air coolers and a 2-stage air filtration system to maintain great quality compressed air for the oxygen concentrator modules. Air coolers remove heat from the compressed air prior to filtration with 2-state filters with moisture drains to remove condensed moisture from the compressed air. By drying and filtering the compressed air the oxygen concentrator modules will last longer and provide higher purity of oxygen in more humid environments. This feature is unique to the TOX-Series and not available in competitor models.



     -Economical - Produce oxygen on-site rather than purchase and re-fill oxygen bottles

     -Reliable operation - Built-in air filtration system and air cooler to remove dust, and moisture from air prior to the oxygen concentrator increasing the long-term reliability of the oxygen concentrator

     -Turnkey operation - only electrical power is required for operation

     -Oxygen purity alarm - built-in oxygen purity alarm will sound an alarm and illuminate a light  to indicate oxygen purity is below 80%

     -Rebuildable - easy to rebuild system with all replaceable parts and components

     -Automated - system is automated and will maintain oxygen pressure in the tank automatically.  System will sit in stand-by but ready for operation when pressure in the tank is above 90 PSI

     -Simple power requirements - Standard power configuration is a L14-20P cord end for a 220v with neutral. 220 VAC, 50 Hz power also available upon request.


What is Pressure Swing Adsorption (PSA)

Clean, dry compressed air is fed into the first molecular sieve bed.  Nitrogen is adsorbed, while oxygen is allowed to flow through.  When the sieve in the first bed becomes full of nitrogen, the airflow is then directed into the second bed.  As the second bed separates the oxygen from the nitrogen, the first bed vents its nitrogen into the atmosphere.  Compressed air is once again fed into the first bed, and the process is repeated continuously.  A constant flow of oxygen is reliably produced.
