Multi-Leaf Damper JK-LP / JK-LU Description Application range The multi-leaf dampers types JK-LP 180 and JK-LU 180 are used in ventilation and air-conditioning systems as control, throttle or shut-off dampers for the pressure and volumetric flow regulation. The flow-favouring aluminium blades are adjusted together, rotating in opposite directions, via external plastic gear wheels. The external arrangement of the gears has the benefit that in comparison to internally arranged wheels exposed to the air flow, they do not become soiled so quickly. A cover plate protects the gear wheels from outside...

Multi-Leaf Damper JK-LP / JK-LU Models and dimensions Dimensions JK-LP 180 (with plastic bearing) JK-LU 180 (with sintered bearing) When selecting the multi-leaf dampers, the permitted width must be selected according to the total pressure loss (see selection table above). Max. differential pressure 1000 Pa. Construction subject to change. All combined lengths and widths available!

“HAK# Corner angle As standard, multi-leaf dampers are supplied with corner angles. The special form of the corner holes allows them to be connected to the connection systems available on the market (e.g. Metu system M 2/M 3) Extended driving axle (-VA) Driving axle left Driving axle right The number of holes does not include the 4 corner holes. Number of holes All combined lengths and heights available. Projection length z = max. 150 mm only together with bearing block (at an extra charge) The above illustration shows the division of multi-leaf dampers greater than 1998 mm in height. The blades...

It is not possible to join the two sections. Drive side 1 "left" and 1 "right". The primed mounting frame 35/35/4 is only available on special request. Vertically and horizontally divided multi-leaf dampers The figure opposite shows the division of multi-leaf dampers greater than 1998 mm in height and width. The blades in the two sections on top of each other are joined by a coupling rod. It is not possible to join the horizontally adjacent...

«h*k#Multi-Leaf Damper JK-LP / JK-LUSelection actuator / servo cylinder JK-LP / JK-LU-E (with electric actuator) The electric actuator or pneumatic cylinder can also be installed at a later stage. When an electric actuator is fitted, a control panel must be attached next to or above the damper during mounting. For standard mounting of a pneumatic servo cylinder, use control panel type I for heights of up to < 565 and control panel type II for heights from > 634. When a thrust actuator or servo cylinder is mounted on site, it is recommended also ordering the bearing block, in order to ensure better...
