Description

Back draft damper for installation in horizontal ducts. The profiled vanes produce a strong upward force which reduces the air resistance. This means that the vanes opens fully at low air velocities as well. The box is manufactured from galvanised sheet steel. The damper inside the box is manufactured in weather-resistant and shock-proof nylon material. The robust construction ensures that the vanes will not become deformed or loose. Air velocity should not exceed 12 m/s.
