Breathing Air Purification System helps remove contaminants from compressed air so it can meet the air-quality requirements of its intended breathing application. These systems are important in industries where workers use supplied-air respiratory equipment, including suitable breathing apparatus and other specialized respiratory protection systems.
Compressed air may contain moisture, oil aerosols, particles, or other contaminants. Therefore, a properly selected purification system helps improve air quality when designed, installed, and maintained according to the required specifications.
What Is a Breathing Air Purification System?
A breathing air purification system is a specialized arrangement of filtration and treatment components designed to process compressed air for breathing applications. Depending on its design, the system may include moisture separators, coalescing filters, activated carbon filters, dryers, and other purification stages.
Each component serves a specific purpose. However, the complete system must be suitable for the compressor, air source, intended application, and applicable breathing-air quality requirements.
How Does a Breathing Air Purification System Work?
The purification process varies according to the equipment configuration. A typical system may use the following stages:
- Moisture separation: Removes liquid water and helps reduce excess moisture.
- Particle filtration: Captures dust and other solid particles.
- Oil aerosol removal: Uses suitable filtration elements to reduce oil droplets and aerosols.
- Adsorption filtration: Activated carbon or other appropriate media may reduce certain vapours and odours.
- Air drying: A suitable dryer reduces moisture to the specified level.
- Air-quality testing: Appropriate testing verifies whether the treated air meets the required breathing-air specifications.
Importantly, not every system contains all these stages. Also, ordinary filters cannot remove every possible contaminant. Carbon monoxide and other hazardous gases require specific controls, suitable treatment technology, and appropriate monitoring where necessary.
Benefits of a Breathing Air Purification System
A properly designed system offers several benefits:
- Improved air quality: Helps reduce specified contaminants in compressed air.
- Respiratory protection support: Provides treated air for compatible breathing apparatus when the complete system meets applicable requirements.
- Moisture control: Helps protect downstream equipment from excessive moisture.
- Equipment reliability: Appropriate filtration can help reduce contamination-related problems.
- Industrial safety support: Helps organizations manage breathing-air quality as part of a wider respiratory protection program.
Applications of Breathing Air Purification Systems
Breathing air purification systems may be used in industrial facilities, confined-space operations, painting and coating applications, chemical processing, and other workplaces where approved supplied-air respiratory protection is required.
They may also form part of suitable breathing-air compressor installations. However, systems intended for scuba diving or other specialized applications must meet the specific requirements of those uses.
Maintenance and Safety Requirements
Regular maintenance is essential for dependable performance. Operators should replace filters according to the manufacturer’s instructions, inspect connections for leaks, maintain dryers and separators, and monitor relevant pressure and air-quality indicators.
Furthermore, breathing air should be tested at the required intervals for the contaminants specified by applicable standards. A filter’s presence alone does not prove that air is safe to breathe. The compressor intake location, compressor condition, treatment equipment, and distribution system must also be evaluated.
