Stainless Steel Supply Air Valves
Reliable airflow control for supply ventilation systems
Our stainless steel supply air valves offer a durable and hygienic solution for controlled air delivery in mechanical ventilation systems. Commonly installed in bathrooms, kitchens, and commercial spaces, they help maintain optimal indoor air quality and comfort.
Manufactured from stainless steel, these valves provide enhanced resistance to corrosion, moisture, and wear, making them suitable for more demanding environments compared to standard painted or plastic valves.
Each valve features an adjustable central cone, allowing for accurate airflow balancing during setup — ideal for both new builds and retrofit applications.
Key Features:
- Stainless steel construction
- Adjustable inner core for precise airflow control
- Surface-mounted for ceiling or wall installation
- Natural stainless steel finish
- Available sizes: 100mm & 125mm
Please note: Images shown may include both supply and extract models. Supply and extract valves differ by their dome shape — exverted for supply, inverted for extract — to optimise airflow direction.
