VAV Controller Type RND

The Variable Air Volume (VAV) Controller type RND is a round, compact blade type damper c/w integral differential pressure sensor and Belimo controller. The VAV controller type RND can provide constant and variable air flows, the controller measures the differential pressure within the damper blade zone when enables a stronger signal to be obtained due to increased air velocities at measurement point.

VAV Controller Type RCT

The Variable Air Volume (VAV) Controller type RCT is a rectangular, compact blade type damper c/w integral measuring probe sensor and Belimo controller. The VAV controller type RCT can provide constant and variable air flows, the controller measures the differential pressure using two pressure integrating probes located within the damper casing. One probe is located at the front of the damper measuring total pressure, with the second probe located after the damper in the accelerated airflow path.
