POOL: Type JZ · JNE · JZ-L · JZD-G

Multileaf dampers are used to isolate and restrict the airflow in ductwork and other openings.


Multileaf dampers are primarily used in ventilation systems for volume flow and pressure control.

  • Multileaf dampers are available in a variety of constructions, up to a leak-tightness level acc. to DIN 1946 or DIN EN 1751.
  • Made of steel, stainless steel or aluminium.

In addition, the JZ-L and JZD-G type satisfied the closed blade leakage requirements specified in DIN 1946 (leakage < 10 m³/h · m² of damper cross-section with a 100 Pa pressure differential).

The aerofoil section blades are coupled by external linkage, which can provide either parallel or opposed blade operation, or in the case of JZ-G and JZD-G type, opposed blade action only, via gears.

The damper of the JNE type is entirely constructed from stainless steel and is suitable for applications where a high level of corrosion resistance is required.

The damper has to be installed with horizontal blades.
