Louvred External Wall Vent with Backdraft Shutter
Luxair louvred external wall vents combine a durable polymer construction with a built-in backdraft shutter system — preventing cooking odours, cold draughts, and insects from entering the property through the wall duct when the extractor is not in use. Available in five colours and three sizes to suit any exterior finish and any standard ducting diameter up to 150mm.
Red Dot Design Award Winners
These vents are Red Dot Design Award winners — recognised for combining aesthetic appeal with practical ventilation performance. The louvred face design provides effective airflow when the extractor is running while maintaining a clean, considered appearance on the external wall.

Material and Durability
Constructed from robust UV-resistant polymer — will not fade, discolour, or degrade in harsh weather conditions over time. The backdraft shutter is built into the vent body and operates mechanically — opening under airflow pressure from the extractor and closing when the extractor is off, blocking reverse airflow without any power or maintenance requirement.
Pair With the Luxair Heat Retention Cartridge
For maximum energy efficiency — particularly in airtight or modern fabric-first homes — pair these louvred vents with the Luxair heat retention valve. The combination eliminates backdrafts entirely and significantly reduces heat loss through the wall duct when the extractor is not running. Click here to view these.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting
