Why this ducting earns its place
Every extraction system has points where ducts meet and diameters shift. A 300 mm branch feeding a 350 mm riser, or stepping back down—these transitions need a smooth converter to avoid turbulence and air leakage. This 300–350 mm converter is exactly that: a reliable bridge between two common extraction duct sizes.
At 3 kg, it's straightforward to handle and position during installation. The converter's design lets airflow step smoothly from one diameter to the other without pressure loss or velocity disruption. Install it between hood ducting and your main extraction stack, or anywhere your system needs to change from 300 mm to 350 mm (or the reverse). One end seats the 300 mm duct, the other accepts the 350 mm—secure both with clamps and you're done.
The right converter in the right place keeps extraction working properly: smooth air movement, minimal noise, and balanced pressure throughout. Just measure your existing ducts before installation to confirm you've got the correct size pair.
