Breathing Air Purification System Types Uses & Price in Pakistan. Breathing Air Purification System is a specialized filtration and air treatment solution designed to produce clean, safe, and breathable compressed air for respiratory protection systems such as SCBA (Self-Contained Breathing Apparatus), airline breathing apparatus, and scuba diving cylinders. These systems remove moisture, oil vapors, carbon monoxide, carbon dioxide, particulates, and harmful gases from compressed air supplies.
International compressed breathing air quality standards are guided by the National Fire Protection Association (NFPA 1989 & 1984), International Organization for Standardization (ISO 8573), and Compressed Gas Association (CGA Grade D breathing air).
In Pakistan, regulatory compliance aligns with the Pakistan Standards and Quality Control Authority (PSQCA) and industry-specific safety frameworks.
🔎 What is a Breathing Air Purification System?
A Breathing Air Purification System is an engineered filtration unit installed between an air compressor and breathing apparatus cylinders or airline systems. It ensures the compressed air meets breathable air standards before being supplied to users.
The system performs:
- Removal of oil aerosols and vapors
- Moisture separation and humidity control
- Carbon monoxide (CO) removal
- Carbon dioxide (CO₂) reduction
- Dust and particulate filtration
- Odor elimination
- Final air quality polishing
It is essential for firefighting departments, oil & gas industries, offshore platforms, diving centers, hospitals, and confined space operations.
⚙ Working Principle of Breathing Air Purification
Breathing Air Purification System Types Uses & Price in Pakistan:
1️⃣ Ambient air enters the compressor
2️⃣ After-compressor cooling reduces air temperature
3️⃣ Moisture separator removes condensed water
4️⃣ Multi-stage filtration cartridges remove oil and particles
5️⃣ Activated carbon eliminates odor and hydrocarbon vapors
6️⃣ CO catalyst converts carbon monoxide to safer levels
7️⃣ Final filtration ensures Grade-D or EN-compliant air
8️⃣ Purified air is delivered to cylinders or airline manifolds
Continuous air monitoring systems may be installed to detect carbon monoxide levels in real time.

After exposure to smoke or toxic gases, refill air must meet NFPA and CGA safety standards.
✅ Airline Breathing Apparatus
Used in:
- Confined space entry
- Tank cleaning operations
- Chemical plants
- Shipbuilding yards
- Oil & gas facilities
Purification systems ensure continuous supply of breathable air through long hose lines.
✅ Scuba Diving Equipment
Breathing air purification systems are critical for maintaining safe air quality for:
- First-stage scuba regulators
- Second-stage regulators
- Octopus regulator
- Buoyancy Control Device (BCD) inflator
- Submersible Pressure Gauge (SPG)
- Diving cylinders (steel & aluminum tanks)
- Dive air cascade storage banks
Contaminated compressed air can cause serious diving accidents including CO poisoning and regulator malfunction. Diving centers in Karachi and coastal regions rely heavily on high-grade filtration systems.
✅Breathing Apparatus Cleaning Kit
A Breathing Apparatus Cleaning Kit is a complete set of cleaning tools and approved disinfectants used to:
- Remove dirt, oil, and contaminants
- Disinfect face masks and regulators
- Clean air supply hoses
- Prevent bacterial and fungal growth
- Maintain hygiene after emergency or diving operations
🎒 Other Essential Scuba Items
In addition to purified breathing air systems, professional diving setups include:
- Scuba diving masks
- Fins and booties
- Dive computers
- Underwater compasses
- Exposure suits (wetsuits & drysuits)
- Dive knives and cutting tools
- Surface marker buoys (SMB)
- Oxygen analyzer (for Nitrox diving)
- Cylinder valves and tank boots
- Gear carrying bags and protective storage cases
Proper maintenance of all scuba items ensures diver safety and equipment longevity.
