KWP-L
Special execution of dampers.
The dampers may also be fitted with limit switches indicating the open or closed position of the baffle.
KWP-L dampers may be fitted with inspection openings for checking the damper condition once it is installed in the
ventilation system.
In a special version, resistant to aggressive environments, all components of the damper are made of stainless steel,
whereas the damper baffle is impregnated with a fire-resistant board impregnation.
