Transition box AST DN90/125 (OD90–ID75 / Ø125)400mm

Product Description

Supply and Exhaust box AST 1xDN90/125 – 400 mm is a specialized transition component for ventilation and duct systems, designed to ensure reliable transfer and distribution of air between ducts of different diameters. The box is manufactured with an inlet diameter DN125 and one outlet DN90 at a 90° angle, which enables efficient integration into distribution networks while maintaining minimal pressure losses and constant airflow.

This component is suitable for residential, commercial, and industrial applications within HVAC (Heating, Ventilation, and Air Conditioning) systems, where precise connection of main distribution lines with smaller branches is required.
