The VAV Compact Controllers consist of a differential pressure sensor, actuator and digitally configurable control electronics. They are intended for mounting on damper shafts of a minimum length of 30 mm. They consist of base and 2-sectional housing.

Components contained in the base:

  • Steel base plate with damper drive shaft fixing for different drive shaft diameters / cross-sectional areas (cf. section 2.3) and angular rotation limiter,

  • maintenance-free, low-noise gear train,

  • magnetic hysteresis clutch with practically contact-free force transmission; this means that the actuator is locking- and overload-proof, also in continuous operation.

Components contained in the housing (Note: the housing cover can’t be removed):

  • controller electronics,

  • differential pressure sensor,

  • synchronous motor for the damper actuator.
