Features and Advantages


1. Large-capacity dual-tube design for more stable air supply

• A large 150L gas storage capacity makes it suitable for long-term continuous oxygen supply (such as in hospital ICUs and high-altitude rescue operations).

• The dual-tube parallel structure provides redundant backup, ensuring continued air supply even if a single tube fails, enhancing safety.

2. High-pressure output for medical and rescue needs

• Output pressure can reach over 30 MPa (300 bar), meeting the air supply requirements of high-pressure breathing equipment (such as diving and high-altitude oxygen chambers).

• Precision pressure regulation ensures stable airflow and prevents pressure fluctuations that could affect patients or users.

3. 100% oil-free, pure air

• Medical-grade, oil-free compression technology, compliant with ISO 8573-1 Class 0 standards, eliminates the risk of oil contamination.

• A multi-layer filtration system (activated carbon, precision filter element) ensures sterile and particulate-free air, making it suitable for respiratory therapy.


Application Industries

High pressure breathing air filling compressors are widely used in scuba diving,  firefighting, marine, paintball, aerospace, aquaculture, golf course and other  fields.


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.
