From 600mm
These 600mm spiral duct reducers connect 600mm (approx. 24″) diameter spiral ducting to a smaller duct size, stepping down to 9 smaller diameters, from 560mm right down to 250mm. Reducers are the standard way to drop duct diameter through a system as airflow splits off along the run, keeping air velocity where the design needs it. All 9 options on this page reduce from a 600mm end. Orders over £400 ex VAT qualify for free UK mainland delivery, and every size is made to order and despatched in 3-5 working days.
