280mm Branch

Choose a 280mm curved boot saddle to tee a 280mm branch line off your spiral ducting. The curved (swept) boot profile eases air from the main spiral duct into the branch, making it a popular take-off for dust and fume extraction systems. The options below share the same 280mm branch outlet and differ only by main duct size, to suit main duct diameters from 280mm to 1000mm (15 sizes). Alpha Air is a Leicester-based ventilation supplier — these fittings are made to order and despatched in 2-3 working days.

Every other branch diameter is available under 90 Degree Curved Boot.
