FabricAir can make concentric or eccentric reducers in any taper ratios desired.
FabricAir elbows are produced on demand. We can make the standard 22.5°, 45° and 90° or any angle in between, as we tailor the system to your specific needs. The centerline radius of the elbows is 1X diameter, which means that the centerline radius of the elbow is equal to the diameter of the duct. An elbow above 70° is produced using four gores; anything less is two gores.
