Overview
Precision Duct Fittings for Smooth Airflow and Accurate Fitment
NESF fabricates duct fittings that support smooth airflow and clean integration with fans, AHUs, blowers, scrubbers, and process equipment.
Accurately made fittings help reduce turbulence, vibration concerns, pressure losses, and installation rework.
Share your fitting drawings, interface dimensions, airflow direction, material, and site constraints. NESF will propose a fabrication-ready fitting scope.
Product Range
- Square-to-round, rectangular-to-rectangular, and offset transitions.
- Concentric and eccentric reducers or expanders.
- Radius, segmented, gored, and vaned elbows where required.
- Branch take-offs, shoe taps, and splitter sections.
Fabrication Details
