PSA Oxygen Generator is a low-power oxygen supply device specially designed for mine
emergency rescue scenarios. Based on pressure swing adsorption
technology, it adopts a high-efficiency and energy-saving molecular
sieve system to stably produce high-purity oxygen (93%) at a low
power consumption of 50kW. It features core advantages of fast
startup, strong mobility, resistance to harsh environments, and
long battery life. As an emergency-specific model of Vacuum Pressure Swing Adsorption Oxygen Systems, it adopts a trailer-mounted design, enabling rapid arrival at
mine accident sites and starting oxygen supply within 10 minutes.
It provides continuous oxygen support for trapped miners and
rescuers, while adapting to ventilation and oxygen supplementation
in hypoxic underground mine environments, serving as an
indispensable life support equipment in the mine emergency rescue
system.

Mine mining environments are complex, prone to accidents such as
collapses, water inrushes, and gas explosions, leading to hypoxia
or excessive concentrations of toxic gases underground. The golden
rescue period is only 72 hours, imposing extremely high
requirements on the response speed, mobility, and endurance of
oxygen supply equipment. Traditional mine emergency oxygen supply
relies on oxygen cylinders and oxygen respirators: oxygen cylinders
have short endurance (only 2-4 hours of oxygen inhalation per
person), and oxygen respirators are suitable for personal
protection, failing to meet the needs of simultaneous oxygen supply
for multiple people and long-term rescue.
The 50kW low-power design of the PSA Oxygen Generator is adapted to mine emergency scenarios. It can be powered by
diesel generators or mine backup power supply, with a continuous
operation time of ≥72 hours, fully covering the golden rescue
period. The 93% oxygen purity can quickly relieve hypoxia symptoms,
avoiding confusion or life-threatening risks for trapped miners due
to oxygen deficiency. The 30Nm³/h flow rate can support 20-25
people to inhale oxygen simultaneously (1-1.5Nm³/h per person),
meeting the synchronous oxygen supply needs of rescue teams and
trapped personnel. Its trailer-mounted mobile design is suitable
for rugged mine roads, equipped with a four-wheel drive traction
system that can travel on roads with a slope ≤30°, arriving at
accident sites quickly – its response speed is 80% faster than
traditional oxygen supply methods. As an emergency model of psa gas plant, it requires no external equipment, can be started immediately
after unpacking, and is simple to operate – rescuers can master it
after simple training.
As an emergency reserve equipment for mines, the PSA Oxygen Generator must be maintained in good condition at all times to respond to
sudden accidents.
- Daily maintenance: Start the equipment to run for 30 minutes
monthly to inspect the operation of core components such as fans,
generators, and control systems, ensuring no faults. Clean the air
intake filter weekly and replace it monthly to avoid dust blockage
affecting air intake volume; test the adsorption performance of the
molecular sieve every six months, and regenerate or replace it in a
timely manner if purity decreases (normal service life is 2-3
years).
- Storage requirements: Store the equipment in a dry and
well-ventilated warehouse, take anti-freezing measures in winter to
prevent freezing of water tanks and pipelines; regularly replace
engine oil and filter elements of the diesel generator, and keep
the fuel tank at more than 1/3 full to ensure rapid startup in
emergencies.
- Reserve management: Establish equipment maintenance records, with
special personnel responsible for management, and conduct a
comprehensive inspection quarterly, including tire pressure,
flexibility of support legs, and insulation of the electrical
system. In addition, equip sufficient spare parts such as filter
elements, seals, and oxygen masks to ensure quick replacement in
case of faults without affecting emergency use.
With its 50kW low-power consumption and rapid response advantages,
the PSA Oxygen Generator has become a life support equipment for mine emergency rescue. Its
vpsa oxygen generator technology can provide continuous and stable oxygen support for
rescue sites. Combined with standardized maintenance and rapid
deployment, it can maximize the safety of miners and rescuers,
improving mine emergency rescue capabilities.
In addition to PSA Oxygen Generators, we also produce VPSA Oxygen Generators, storage tanks, heat exchangers and other
products. If you are interested in VPSA Oxygen Systems or other
