## Overview

The LIRAST 100 mm VMC Double Flow Ventilation System combines innovative ceramic heat recovery with a silent axial fan to deliver efficient, quiet air circulation. Designed for wall thicknesses between 300-550 mm, it recycles up to 85% of heat from expelled air, reducing energy loss while maintaining fresh airflow at speeds of 30 to 45 m³/h. Its durable ABS grille withstands weather exposure, and the easy-to-use wall switch offers two-speed control. Lightweight and compact, this European-made unit is ideal for upgrading single-room ventilation without complex ductwork.

## 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: Für einen vorhandenen Mauerdurchbruch mit einem Lüftungsrohr von 125mm Durchmesser fand ich nur diesen Lüfter mit Keramikwärmetauscher. Alles passte und war sehr leicht zu installieren. Es funktioniert wie beschrieben. Ich gehe von einer hohen Wärmerückgewinnungsrate aus. Um den Wärmeverlust möglichst ganz auszugleichen, habe ich mir einen kleinen Vorbau mit Silikonheizkabel (niedrige Wattzahl) installiert. Schade, dass der Industrie zum Thema Wärmeverlustausgleich mit geringem Energieeinsatz so rein gar nichts einfällt. Mir wäre es einen Aufpreis wert gewesen. Die Geräuschemission finde ich o.k. Alles in allem kann ich das nur wenige Watt je Stunde verbrauchende Gerät empfehlen.
Review: senza dubbio un buon prodotto sono io che non ho fatto il foro giusto, mi aspettavo che per 100 mm si intendesse veramente 100 mm invece è 108

*by A***E on 13 January 2025*

Overall very happy with this unit. You can (accidentally) leave it on for hours and come back and still find the bathroom is perfectly warm. This is in contrast to previously when if I forgot to close the window the room would be freezing. Only quibble is that it is maybe slightly loud. I usually wait to turn it on until after I've left the room.
