A circular single-row louvre air vent with fixed straight blades. Because the blades are fixed there are no moving parts to rattle or drift, which makes it the low-maintenance choice for exhaust and supply terminals in residential fresh air systems. The spring-buckle ring lets it snap into a ceiling opening without screws, and the ABS face wipes clean.
