Tronic Exhaust Fan Disc Valve Cover 200mm Aluminum with Removable Core
TSh 28,000
Our review
This Tronic exhaust fan disc valve cover is a 200mm aluminum fitting with a removable core, designed to sit over an exhaust fan opening and close off the duct when the fan is not running. The disc valve design uses a circular flap that opens with airflow and drops shut afterward, which helps keep out rain, dust, insects, and backdrafts. The removable core makes cleaning and inspection easier, since you can take out the inner section without dismantling the whole cover. It suits homeowners, builders, and anyone fitting ventilation in a kitchen, bathroom, or utility room where a 200mm fan is already planned. Before buying, confirm your fan or duct opening actually measures 200mm, check that the mounting surface is flat and strong enough, and decide whether you want the flap to open outward or inward. Compare it with plastic covers, which cost less but may yellow or crack in strong sun, and with fixed louvre grilles that do not seal as tightly. Aluminum is the main draw here, so weigh that against the finish and thickness of alternatives. Available on Sokonia.
