A 225-350 bar high-pressure breathing air compressor is a device specifically designed to produce pure, breathing-grade compressed air. Operating within an extremely high pressure range (approximately 3250-5000 PSI), its core function is to filter and compress ambient air through multiple stages of precision filtration, thoroughly removing oil, moisture, dust, harmful gases, and odors. Ultimately, it produces clean, high-pressure air that meets stringent medical or respiratory safety standards, which is then filled into cylinders or air bags.

Product features
1. High Safety
◦ Multi-stage precision filtration system
◦ Multiple safety features: Equipped with automatic pressure shutdown, overheat protection, overpressure relief valve, and monitoring instruments, ensuring reliable operation.
2. High Output Pressure and Stability
◦ Capable of consistently delivering output pressures from 225 bar to 350 bar, or even higher, it meets the filling requirements of various high-pressure gas cylinders with high filling efficiency.
3. Dedicated Design and Long Life
◦ Oil-free or minimally lubricated design eliminates oil contamination at the source, ensuring pure air and reducing maintenance.
◦ Core components are constructed of special wear-resistant and corrosion-resistant materials for durability.
4. Intelligence and Convenience
◦ Modern models are often equipped with an intelligent control panel that provides real-time monitoring of pressure, temperature, operating time, and filter life.
◦ Highly automated, it features automatic startup, operation, shutdown, and water discharge, ensuring easy operation.
Application Industries
This compressor primarily serves applications requiring extreme air purity and safety:
1. Firefighting and Emergency Rescue: Filling firefighters' Self-Contained Breathing Apparatus (SCBA), standard equipment in fire stations.
2. Industrial Safety: Providing long-line air supply or SCBA air source for workers in industries such as petrochemicals, natural gas, shipping, and mining, for entry into hazardous or oxygen-deficient environments.
3. Diving and Water Works: Hookah Diving: Providing a continuous supply of breathing air for shallow-water divers.
5. Diving Cylinder Refilling: Filling high-pressure air cylinders for recreational and engineering diving.
6. Medical and Aerospace: Providing high-pressure medical air to hospitals (such as operating rooms and ICUs), as well as for aviation breathing systems and some flight test equipment.
7. Sports: Filling competition air rifles and air pistols.
FAQs
Q1: Is maintenance required?
A: The filter needs to be replaced regularly and the seal needs to be checked.
Q2: Is the pressure adjustable?
A: Most models are adjustable, depending on the usage requirements.
Q3: Which is better, oil-free or oil-based?
A: Oil-free is safer and suitable for breathing; oil-based requires strict filtration.
Q4: How long does it take to inflate?
A: It depends on the size of the cylinder and the power of the compressor (from a few minutes to several hours).
Q5: Can it be breathed directly?
A: It must be filtered (to remove water, oil, CO, etc.) to ensure safety.
