TECHNICAL DESCRIPTION
The WKP-O dampers are made up of a rectangular housing, movable blades and a drive system.
The dampers’ housing is made of fire
-rated boards and steel structural members. Both sides of the housing are
equipped with steel connection spigots, which enable easy connection of a duct.
Movable blades, made of mineral silicate composite, are fastened to the housing by means of metal pins.
There are intumescent seals mounted on the inner side of the housing and on the blades. Their characteristic feature
is the volume increase at high temperatures, tightly filling all leaks between the baffle and the body. A bubble seal
ensures the leak tightness at ambient temperature.
The WKP damper is provided with an innovative actuating mechanism, which ensures the counter rotation of the
blades. The mechanism is made up of, among other things, gears made of fire-rated materials, blades and an electric
actuator.
During normal operation of the system, the blades are in the open position. The permissible air velocity for the WKP-O
damper in a B x H connection duct is 12 m/s.
The WKP-O damper is equipped with an electric spring return actuator of BF or BFN series by BELIMO and a BAT or
BAE thermal fuse (72 ° C) (optionally 95 ° C), which is the damper's drive system with AC 230 V or AC / DC 24V
The range of dampers covers the following dimensions: a clear damper width from 200 to 1200 mm (10 mm intervals)
and clear damper height from 200 to 800 mm (100 mm intervals).
