Extract units


Low-pressure demand controlled extract grille

A unique solution accurately optimised for Passive Stack and Hybrid Ventilation

The G2H is the first extract grille accurately optimised for passive stack and hybrid ventilation, for both new-build and refurbishment projects. By offering both automatic modulation of airflow according to need, and boost airflow (manual or automatic), the G2H advantageously combines energy efficiency and indoor air quality.

Its installation onto existing ductwork is particularly easy, since it fits directly onto collective or individual ducts designed for passive stack, or hybrid ventilation.
