The TOX-40 Oxygen Generator is a reliable, rebuildable, and economical solution for generating oxygen at 40 SCFH flow rates with up to 20 PSI continuous pressure. Designed for higher-flow applications where large industrial concentrators aren’t practical, the TOX-40 delivers dependable performance in a compact, easy-to-maintain package.
Whether you supply it with 8 CFM of compressed air or choose the optional internal compressor package, the TOX-40 is a complete turnkey oxygen generation system.
Key Features
Dependable Operation
Built for thousands of hours of continuous service, the TOX-40 has only one valving action, meaning very few moving parts to wear out. The zeolite sieve material, which adsorbs nitrogen, is sealed in rugged aluminum cylinders and rarely requires replacement.
Fully Rebuildable
Unlike many oxygen concentrators, the TOX-40 is designed to be completely rebuildable. Key components such as sieve beds and valves can be cleaned, replaced, or rebuilt—extending the unit’s lifespan indefinitely.
- All replacement parts are stocked and available
- Optional flat-fee rebuild program – receive a rebuilt TOX-40 and send back your used unit with the included return label
This ensures your oxygen generator keeps running reliably for years at minimal cost.
Economical Long-Term Value
Because it can be rebuilt instead of replaced, the TOX-40 offers a much lower total cost of ownership compared to single-use models. Long service life, low maintenance requirements, and rebuildability make it one of the most economical oxygen generators on the market.
Made in the USA
Every TOX-40 is manufactured, assembled, and tested in the USA, ensuring quality craftsmanship and reliable support.
Compressed Air Options
Standard – External Compressed Air
The TOX-40 in its standard configuration requires 8 CFM of compressed air at 50 PSI or higher. Using an external air source offers:
- Better quality control of compressed air and filtration
- More effective moisture removal
- Lower maintenance and reduced power consumption (since only the plant compressor runs, rather than multiple small compressors)
Optional – Internal Air Compressors
For locations without a compressed air source, the TOX-40 can be equipped with two oil-less internal compressors (1/3 hp each).
- Designed for reliability (rebuild required after ~8,000 hours)
- Includes air coolers and a 2-stage filtration system to remove moisture and protect the oxygen concentrator modules
- Ensures high oxygen purity even in humid environments
Note: In environments above 95°F with high humidity or standing water, extra provisions should be made for air drying to protect the system.
How It Works – PSA Technology
The TOX-40 uses Pressure Swing Adsorption (PSA) to generate oxygen:
- Clean, dry compressed air is fed into the first molecular sieve bed.
- Nitrogen is adsorbed, while oxygen passes through.
- Once the first bed is saturated, airflow switches to the second bed.
- The first bed vents nitrogen to the atmosphere, regenerating itself.
- The process alternates continuously, producing a constant flow of high-purity oxygen.
Why Choose the TOX-40?
- High output: 40 SCFH oxygen at up to 20 PSI continuous pressure
- Durable: Thousands of hours of reliable service
- Rebuildable: Long-term cost savings with replaceable parts
- Flexible: Works with external compressed air or optional built-in compressors
- American-made: Built and tested in the USA
The TOX-40 is the ideal oxygen generator for industries that demand higher flow rates without the cost, size, or maintenance requirements of large industrial systems.
