Solid and Practical Ducting Adapter
This Kair ducting reducer does exactly what it is designed to do and fits well within a ventilation setup. The 100mm to 80mm reduction is accurate and makes it easy to connect different sized ducting or extract fans without hassle. The plastic feels reasonably sturdy and the fitting is tight enough to prevent air leaks once installed properly. It integrates well into existing ducting systems and provides a secure connection when clamped. Installation is straightforward and it slots into place without needing any modifications. For DIY ventilation projects, it is a simple and effective solution that saves time and effort. The only reason for four stars instead of five is that the plastic feels slightly lightweight, so care is needed during installation to avoid stressing the joints, but once fitted it performs well. Overall, a reliable ducting connector that does its job effectively and is good value for ventilation or extraction setups.

perfetto e funzionale
il riduttore è un pezzo molto semplice ma trovarlo in giro diventa complicato i negozi non lo tengono e tanto meno le ferramente, qui è diventato tutto semplice e si adatta perfettamente ai tubi da ridurre

La disponibilité
On avait pas ce produit en quincaillerie. J avais acheté une hotte et oh non!! Les normes ont changées. La solution était de repercer un mur de 1.5 m en briques ( des heures de travail😣) au dernier moment j ai penser à Amazon et 8.00€ et 1 jour plus tard ma hotte est poser et en état de fonctionnement.😥

Riduttore come da aspettative
Il pezzo è perfettamente in accordo alla descrizione e rispetta le aspettative. Buona sia manifattura che i materiali utilizzati. Lato 125mm il componente ha la dimensione del tubo, quindi per una eventuale connessione ad un tubo occorre prevedere un raccordo.
