Supply and exhaust box AST 2xDN75/125 – 400mm

Product Description

Supply and Exhaust box AST 2xDN75/125 – 400 mm is a specialized transition component for ventilation and duct systems, designed to ensure reliable airflow transfer and distribution between ducts of different diameters. The box is manufactured with one inlet DN125 and two outlets DN75 at a 90° angle, which allows 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 the connection of main distribution lines with smaller branch ducts is required.
