Product details

JLS multileaf dampers are made of galvanised sheet steel. They are control and shut-off dampers for ventilation systems, suitable for installation with horizontal and vertical blade alignment. The contours of the aerodynamically shaped hollow body blades merge smoothly into the elastic seals attached to the face of the blades. The casing frames are 120 mm long and have edged connecting flanges. The blade coupling takes place in oppossed blade operation or parallel operation by gear and an external linkage with complete enclosure. Drive and bearing axles made of stainless steel are placed in plastic bearing bushes. Maintenance-free. With external position indicator.
