Special finishes with duct connection spigots
and truncated conical transformations
Reducers
Subject to checking with the Commercial Department, it is possible to supply rectangular and circular dampers with
transformation spigots on request as a non-standard finish.
These couplings may require a longer frame length than the defined standard in order to avoid the opening/closing of
the blade from interfering with the spigot connections.
Length of the frame assembly in relation to the height of the damper.
