## Overview

The LIRAST 100 mm VMC Double Flow Ventilation System combines innovative ceramic heat storage with a powerful axial motor to deliver efficient, silent air circulation. Designed for wall mounting in rooms with 300-550 mm wall thickness, it recovers up to 85% of heat while maintaining fresh airflow at speeds of 30 to 45 m³/h. Its durable ABS grille and easy-to-use switch make it a smart, energy-efficient upgrade for modern living and working spaces.

## Description

Install this quiet central heat exchanger for constant cool airflow with minimal heat loss. The system ensures optimal and efficient ventilation of a single room and can be placed in any room. This is a simple solution if you want a WRGG system without having to install a brand new channel system in the house. Only one channel is needed. The air and the air supply are in the same tube and are exchanged every 70 seconds. Heat from the polluted and expelled air is collected in the heat exchanger (ceramic). Then the fresh air is heated. This WRG device is connected to the electrical network, as is the switch. The switch turns the device on or off and switches to speed I or II mode. The productivity of the WRG device is 30 m3/h in position I and 45 m3/h in position II. Made in Europe.

Review: Easy install and and seems to do what it is supposed to - So far so good - seems to work according to specifications. Will be more interesting in the winter. I replaced the switch with a on ordinary Elko that fit the rest of my power outlets. Like installing a lamp with two feeds.

### ⭐⭐⭐⭐⭐ Easy install and and seems to do what it is supposed to
*by Z***S on 11 July 2022*

So far so good - seems to work according to specifications. Will be more interesting in the winter. I replaced the switch with a on ordinary Elko that fit the rest of my power outlets. Like installing a lamp with two feeds.

### ⭐⭐⭐⭐⭐ Aérateur avec un bon rapport qualité-prix
*by L***O on 20 January 2025*

Aérateur double flux utilisé pour ventiler une cave. Notice un peu succincte mais simple à brancher. L'aérateur est un peu bruyant au moment de l'inversion des flux pour une pièce de vie (le moteur s'arrête pour redémarrer dans l'autre sens), sinon il est quand même plutôt silencieux. Cela reste un bon rapport qualité-prix.
