AIRpipe Compatibility Chart
Use this AIRpipe compatibility guide to compare AIRpipe nominal diameters and pipe outside diameters against common aluminum compressed air piping brands, including Transair, AIRnet, Infinity, EQOfluids, Aircom, Prevost, and Sicomat.
Quick answer:
AIRpipe is compatible with many common compressed air piping sizes, especially in smaller DN20 through DN50 ranges. Compatibility should always be confirmed by outside diameter, fitting type, application, and installation requirements before mixing pipe and fittings from different manufacturers.
What Does DN Mean in AIRpipe Sizing?
DN stands for Nominal Diameter. It identifies the approximate pipe diameter in millimeters. For example, DN50 means approximately 50 mm nominal diameter, which corresponds to approximately 2" AIRpipe.
| DN Size | Nominal Diameter | Approximate AIRpipe Size | AIRpipe Pipe OD |
|---|---|---|---|
| DN20 | 20 mm | 3/4" | 20.1 mm |
| DN25 | 25 mm | 1" | 25.1 mm |
| DN32 | 32 mm | 1-1/4" | 32.2 mm |
| DN40 | 40 mm | 1-1/2" | 40.1 mm |
| DN50 | 50 mm | 2" | 50.1 mm |
| DN63 | 63 mm | 2-1/2" | 67.6 mm |
| DN80 | 80 mm | 3" | 84.8 mm |
| DN100 | 100 mm | 4" | 101.8 mm |
| DN125 | 125 mm | 5" | 133 mm |
| DN150 | 150 mm | 6" | 153 mm |
| DN200 | 200 mm | 8" | 205 mm |

Can AIRpipe Replace Transair, AIRnet, or Other Aluminum Pipe?
AIRpipe may be a practical replacement option for some existing aluminum compressed air piping systems, but compatibility depends on pipe outside diameter, connector style, fitting design, pressure rating, and installation condition.
Best Fit
Smaller nominal sizes such as DN20, DN25, DN40, and DN50 are the most common compatibility areas across several brands.
Use Caution
Yellow/workable sizes may be close enough for some applications but are not recommended without confirming tolerances and installation requirements.
Avoid Mixing Without Review
Red/no-match sizes should not be assumed compatible because the outside diameter does not align closely with AIRpipe sizing.
AIRpipe Compatibility FAQ
How do DN pipe sizes convert to inches?
DN, or Nominal Diameter, is a metric pipe sizing reference. Common AIRpipe conversions include DN20 to 3/4", DN25 to 1", DN32 to 1-1/4", DN40 to 1-1/2", DN50 to 2", DN63 to 2-1/2", DN80 to 3", DN100 to 4", DN125 to 5", DN150 to 6", and DN200 to 8". Always verify actual outside diameter before selecting fittings.
How do competitor pipe sizes compare to AIRpipe sizes?
Competitor pipe sizes may use similar DN sizing, but actual outside diameters can vary by brand. To compare another compressed air piping system to AIRpipe, check the nominal DN size, actual pipe outside diameter, fitting style, pressure rating, and installation requirements.
How do I determine if another piping system is compatible with AIRpipe?
Start by measuring the outside diameter of the existing pipe and comparing it to AIRpipe sizing. Compatibility also depends on the fitting design, connector style, pressure rating, pipe condition, and manufacturer requirements. Do not assume two systems are compatible based only on nominal pipe size.
Can AIRpipe replace an existing compressed air piping system?
Yes, AIRpipe can often replace an existing compressed air piping system, including older black iron, copper, galvanized, or aluminum piping. If only part of the system is being replaced, confirm pipe outside diameter, connection method, pressure requirements, and transition fittings before ordering.
Can I expand an existing piping system using AIRpipe?
In many cases, AIRpipe can be used to expand an existing compressed air piping system. Before expanding, confirm the existing pipe size, system pressure, air demand, pipe material, and connection method so the new AIRpipe section is sized and installed correctly.
Can I mix AIRpipe fittings with another brand of aluminum pipe?
Do not assume AIRpipe fittings will work with another brand of aluminum pipe based only on DN size. Always confirm actual outside diameter, fitting design, pressure rating, and manufacturer guidance before mixing components from different compressed air piping systems.
