Rectangular Mechanical CAV Units

Mechanical Constant Flow Dampers adjust the required air flow rate mechanically by themselves. The unit is controlled by a spring operated mechanism without any electrical power.
The controller operates from the minimum response pressure difference up to a maximum pressure of 1000 Pa and an air velocity range of 2-10 m/s. Over this entire pressure range the maximum flow rate deviation is ±10%. The required air flow rate can be changed easily via an allen wrench on the unit.
