G2H Extract Unit - 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.

Fully automatic operation: exhausted airflow according to various parameters such as humidity or presence.

Pull cord, switch and remote control versions for operating the boost airflow.

Indoor air quality and energy savings thanks to the automatic control of airflows.

Very low pressure solution optimised for passive stack or hybrid ventilation, in the new built or in refurbishment.

Fits directly on all types of ducts (collective shunts , individual, concrete or metal).

Completely silent operation.
