UnipipeAIR the perfect modular aluminium compressed air piping system.
It is designed for industrial compressed air distribution networks requiring corrosion resistance, reduced pressure drop and efficient installation without welding. Manufactured from EN AW 6060 – T5 aluminium with internal corrosion protection, UnipipeAIR provides a lightweight, reusable and expandable solution for plant air systems.

Why Compressed Air Piping Design Matters
Compressed air is often described as the fourth utility in industrial facilities. Poor pipe layout, undersized lines and internal corrosion can increase pressure drop and raise energy consumption.
Even a small pressure loss forces compressors to work harder, increasing operating costs. Proper aluminium piping design improves flow stability and reduces long-term maintenance.
Technical Specifications

- External Coating: Polyester powder coating (≥ 60 µm)
- Fittings: Anodized nuts with cataphoresis-treated bodies
- Temperature Range: -22°F to 266°F (extended with alternate O-rings)
How UnipipeAIR Reduces Pressure Drop
The smooth internal bore of aluminium pipe reduces friction losses compared to rougher internal surfaces found in traditional materials.
Pressure drop is influenced by:
- Pipe diameter selection
- Total run length
- Number of fittings and bends
- System demand fluctuations
Correct sizing ensures stable air delivery at the point of use.
Piping Layout Best Practices
Use a Ring Main Configuration
A closed-loop ring main allows air to travel in multiple directions, reducing pressure variation across the system.
Slope Main Lines
Install mains with a slight downward slope to assist condensate drainage.
Install Drop Legs Correctly
Take drops from the top of the main line and include drain points at the base to prevent moisture carryover.
Allow for Future Expansion
Modular aluminium fittings make it easier to extend the network without system shutdowns.
Installation Notes
- Deburr internal and external pipe edges after cutting
- Mark insertion depth before tightening
- Hand-tighten first, then wrench approximately ¼ turn
- Avoid over-tightening
- Fittings are fully reusable
