New air regulating dampers RDM and RDTM

We launch the new generation of air regulating dampers RDM and RDTM from the February 2022.

Main advantages:
> only one single actuator per one damper up to size 2000x2000 mm (RDTM with „fail safe“ function max. two)
> low torque needed to operate the dampers
> air tightness class 3C
> silicone free design (EPDM rubber gaskets)
> solid and aerodynamic shape of blades
> rounded edges of the flange corners
> included in Mansel software (Mandík air-elements calculation tool)
