Which diameter should you choose? Measure the inside of your duct, from edge to edge through the centre: your measurement is the diameter to order (Ø80mm, Ø100mm, Ø125mm, Ø150mm, Ø160mm or Ø200mm).
This 125 mm diameter semi-rigid aluminium duct extends from 1 to 3 m to suit your route: ideal for connecting a ventilation unit to an extract valve without adding bends. Its rigid structure keeps a constant cross-section, which limits pressure loss and noise compared with a crushed flexible duct. Aluminium withstands the temperatures found in stale-air extraction and can be cut to length with a hacksaw. Compatible with standard Ø125 accessories (clamps, valves, reducers).
