Supply valves introduce fresh air into the space; extract valves remove stale air. They're used in residential and commercial MVHR, MEV, and positive pressure ventilation systems wherever a neat, flush ceiling finish is required.\u003c\/p\u003e\n\u003ch2\u003eWhat's the difference between a supply air valve and an extract air valve?\u003c\/h2\u003e\n\u003cp\u003eA supply air valve is designed to distribute incoming fresh air evenly into the room with minimal draught. An extract air valve draws stale air out of the room and into the duct. Some valves are suitable for both purposes.
