A52 Horizontal Face Bars, Shutter Damper

Product Application

Sometimes, grilles or registers can be loud, causing an unwarranted disruption to an otherwise peaceful environment. To solve this issue (without hampering your ventilation needs), we have designed the A52 grilles. Equipped with shutter dampers, these grilles provide a seamless performance while ensuring minimum noise. They are used in high, sidewall applications where their horizontal blades perform exceptionally well to control the incoming airstream. A52 grilles promise versatility with an extensive range of applications including libraries and conference rooms.
