Air Header Distribution System Supplier Guide
Air header distribution systems organize plant or instrument air supply for pneumatic actuators, valve positioners, analyzers and field instruments. This guide helps buyers prepare a clear RFQ for air headers and instrument air distribution manifolds.
Where air headers are used
Air headers are used where multiple pneumatic devices need a clean, organized and isolatable air supply from one common header. They are common in control valve packages, analyzer shelters, instrument racks and plant utility panels.
- Pneumatic actuator and valve positioner supply
- Instrument air distribution around skids and panels
- Analyzer shelter and utility air take-off points
- Maintenance-friendly isolation for multiple outlets
RFQ details buyers should share
The most useful air header enquiry includes outlet count, inlet size, outlet connection, material, valve type, pressure rating, mounting arrangement, drain requirement and quantity. A drawing or photo of the required layout helps reduce clarification cycles.
Selection notes for projects
Specify whether the header is for instrument air, utility air or a special gas service. Confirm NPT, BSP, compression tube or flanged connections early because connection mismatch creates field delays.
Frequently asked questions
What outlet counts are common for air headers?
Common arrangements include 4, 6, 8, 10 and 12 outlets, but custom outlet counts and spacing can be reviewed against project drawings.
What material is used for air header distribution systems?
SS316, SS304 and carbon steel are common choices. Final selection depends on utility service, project specification and site environment.
