ABS-Flansch (quadratisch bis rund)

Sometimes the smallest parts make the biggest difference in how smoothly a system runs. The ABS Flange (Square to Round) is designed to do exactly that — connecting square and round ducts easily and efficiently, all while keeping airflow seamless and stable.

Made from durable white ABS plastic, it’s lightweight yet strong, built to handle the daily demands of ventilation and HVAC systems without warping or cracking. The square‑to‑round shape allows air to transition smoothly between different duct types, improving system performance and reducing turbulence.

To make installation flexible, it comes in several size combinations — for example, 180×180 mm to Ø100 / Ø150 mm or 230×230 mm to Ø100 / Ø150 / Ø200 mm. That means whether you’re fitting a small residential vent or a larger commercial system, there’s a flange ready to match perfectly.

From office buildings and industrial facilities to home HVAC setups, this connector keeps your airflow consistent and your ductwork neatly integrated. Simple, efficient, and built to last — a small component that quietly keeps air moving right where it should.
