Manufactured from \u003cstrong\u003egalvanised steel finished in RAL 9010 white\u003c\/strong\u003e, it provides a durable, professional-grade extract terminal for high-volume commercial kitchens, large open-plan spaces, and industrial extract systems where 150mm terminals are insufficient. The \u003cstrong\u003eadjustable central cone\u003c\/strong\u003e rotates to increase or decrease the annular opening, allowing the installer to set and balance the extract flow rate at each terminal during commissioning. The valve is designed for ceiling or wall mounting directly over the duct penetration point.\u003c\/p\u003e\n\n\u003cdiv style=\"background:#e6f4f3;border:1px solid #c8e6e3;border-radius:6px;padding:10px 14px;margin:0 0 18px;font-size:.88em;color:#444;\"\u003e\n\u003cstrong style=\"color:#005c54;\"\u003eAbout Airwise:\u003c\/strong\u003e A leading UK and Ireland ventilation products supplier based in Tetbury, Gloucestershire — known for quality, integrity, and competitive pricing across the full spectrum of ventilation ducting, valves, and accessories.\u003c\/div\u003e\n\n\u003cdiv style=\"display:flex;flex-wrap:wrap;justify-content:space-around;background:#e6f4f3;border-radius:6px;padding:8px 4px;margin:18px 0;\"\u003e\n\u003cdiv style=\"text-align:center;padding:12px 8px;\"\u003e\n\u003cdiv style=\"font-size:1.5em;font-weight:800;color:#008377;\"\u003e200mm\u003c\/div\u003e\n\u003cdiv style=\"font-size:.82em;color:#444;margin-top:2px;\"\u003eSpigot Diameter\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align:center;padding:12px 8px;\"\u003e\n\u003cdiv style=\"font-size:1.5em;font-weight:800;color:#008377;\"\u003eGalvanised Steel\u003c\/div\u003e\n\u003cdiv style=\"font-size:.82em;color:#444;margin-top:2px;\"\u003eConstruction\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align:center;padding:12px 8px;\"\u003e\n\u003cdiv style=\"font-size:1.5em;font-weight:800;color:#008377;\"\u003eRAL 9010\u003c\/div\u003e\n\u003cdiv style=\"font-size:.82em;color:#444;margin-top:2px;\"\u003eFinish (White)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align:center;padding:12px 8px;\"\u003e\n\u003cdiv style=\"font-size:1.5em;font-weight:800;color:#008377;\"\u003eAdjustable Cone\u003c\/div\u003e\n\u003cdiv style=\"font-size:.82em;color:#444;margin-top:2px;\"\u003eFlow Balancing\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align:center;padding:12px 8px;\"\u003e\n\u003cdiv style=\"font-size:1.5em;font-weight:800;color:#008377;\"\u003eCeiling \/ Wall\u003c\/div\u003e\n\u003cdiv style=\"font-size:.82em;color:#444;margin-top:2px;\"\u003eMounting\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"background:#e6f4f3;border-left:4px solid #005c54;padding:12px 16px;margin:14px 0;border-radius:0 4px 4px 0;font-size:.95em;\"\u003e\n\u003cstrong\u003eExtract vs Supply:\u003c\/strong\u003e The AWMAV200 is the \u003cstrong\u003eextract valve\u003c\/strong\u003e — its inverted (concave) cone geometry draws air evenly from the room into the duct.
