Functional description
Smoke protection dampers with external linkage have opposed action blades.
An external linkage transfers the synchronous rotational movement from the drive arm to the individual blades.
Even large dampers can be safely opened and closed with this type of linkage.
Opposed action blades close at different speeds since the linkage includes a transverse link.
This facilitates the closing process and reduces the closed blade air leakage.
Quick sizing – differential pressure and sound power level for JZ-RS
Smoke protection dampers for use in ventilation plant rooms or in ducts to prevent smoke from spreading; frame made from C-sections, with aerodynamically profiled hollow blades and external linkage, spring return actuator, with general building inspectorate licence Z-78.4-51 from the DIBt, Berlin, Germany.
Can be triggered by duct smoke detectors with general building inspectorate licence, e.g. TROX duct smoke detector RM-O-VS-D or RM-O-3-D.
