Variable and fixed airflow control

In a lab, extract air units with variable flows can be in operation at the same time as other equipment works with constant exhaust air flows. The sum of the exhaust air needs to be balanced via supply air. In this case, the DCV-CF (Pressure Regulator with flow measurement CFL and a damper with damper motor) is installed in the exhaust air duct. The regulator maintains the pressure in the exhaust air duct and simultaneously measures the exhaust air flow.

Regulator CFL reports the measured exhaust air flow through the communication network. DCV-BL (Airflow controller FBL on a damper with measuring flange and damper motor) balances the supply air. Any offset can be set.

Regulator CFL maintains the pressure in the exhaust air duct.

The controllers have a relay function for alarm output.

Readings of actual values ​​and set points can be made via the communication network or via a connected user panel.
