32mm (1-1/4″) Pipe Size Attribute
The Versatile Standard for Commercial Distribution
The 32mm (1-1/4″) size is a popular choice for main ring mains in medium-sized commercial facilities. It provides excellent flow characteristics for air compressors up to roughly 20HP, minimizing pressure drop across the loop while remaining easy to install and support.
Ideal Applications:
- Medium Shop Mains: Primary piping loop for automotive dealerships, larger woodshops, and light assembly plants.
- High-Volume Drops: For very large equipment or manifolds splitting into multiple tools.
- Vacuum Lines: Effective for central vacuum systems in commercial settings.
Selection Tip: Use 32mm for the main loop in facilities running a 10HP to 20HP compressor to maintain stable pressure throughout the building.
