Reduction piece from Ø 180 mm to Ø 160 mm for spiral ducts

With the reducer for spiral ducts, you can easily connect two ducts with different diameters. This reduction piece is suitable for transitioning a spiral pipe or attachment with a diameter of 180 mm to a pipe or attachment with a diameter of 160 mm.

Material
Like our spiral pipes, the reducers are also produced to the highest standards. They are galvanised (Z275) according to the sendzimir process, making them durable in use and guaranteeing a long service life.

Air tightness class
Our spiral pipe reducers comply with the strict airtightness class D quality (ATC 2), according to the EN12237 standard. This ensures excellent airtightness of the reducers and results in low pressure loss.

Ease of installation thanks to rubber seal
The rubber seal, fitted to our fittings as standard, not only ensures an airtight connection, but this so-called safe-connection also ensures that further assembly materials are limited.
