The FSD-VC Volume Control Damper option will be supplied with a choice of three standard actuator options.
The damper allows for the balancing/regulating of ducted airflows where space is at a premium and where aesthetic appearance in open
plan installations is an important factor.
The smooth lines allow for external insulation where required by others.
