G2H

MULTI-CONTROLLED EXHAUST UNIT FOR NATURAL AND HYBRID VENTILATION

A unique solution precisely optimised for natural and hybrid ventilation

The G2H is the first exhaust unit precisely optimised for natural (passive stack) and hybrid ventilation, in both new buildings and renovations. By providing both automatic control of the airflow according to needs and auxiliary airflows (manual or automatic), the G2H exhaust unit advantageously combines energy efficiency and indoor air quality. It offers a very large air cross-section to ensure the airflow even at a very low pressure, from 2 Pa. It is particularly easy to install, since it fits perfectly on collective or individual ducts designed for natural or hybrid ventilation.

A smart and unique exhaust unit

The numerous modules available on the G2H exhaust unit meet various needs and occupancy modes in dwellings: humidity controlled to remove excess moisture quickly, presence detection, and even remote control to exhaust odours are some of the actuation modes available to optimise, at all times and in every room, both indoor air quality and energy consumption.

An optimised solution to improve building energy performance

With settings precisely optimised, the G2H exhaust unit is an especially satisfying response to anyone wishing to combine energy efficiency, quiet operation, and ease of implementation, whether in a new or a renovated building.

A very large air cross-section to accommodate low pressures

With an air cross-section of up to 168 cm² at maximum opening, the G2H exhaust unit ensures airflows even at very low pressure, from 2 Pa.
