Airtight damper designed to regulate supply, recirculating or exhaust air in high-pressure ventilation systems, as well as to seal the internal volume of ventilation networks, the operating pressure of which can reach 2,500 Pa.

Dampers of rectangular cross-sections are produced only.

The KED damper consists of a four-wall box-shaped body reinforced with additional stiff ening elements, made of stainless or low-alloy steel. The leaf of such a damper is made of a special steel profi le. In all design versions of the damper, its leaves do not protrude beyond the body dimensions. An electric drive or a handle for manual control can be used as an actuator (manual control of the electric drive is always available by default).
