VAV-CS air flow regulator can be used both for variable and constant flow and, if appropriate, for forced shut-off for both air supply and air exhaust
Application
Regulating of air volumes to change the temperature or air quality in a room
Control and regulate the supply air flow and exhaust air flow
Airflow range can be set between two set values or as constant airflow
Material
Galvanized steel
Composition
Operating range is between 2 to 12 m/s
Integrated flow measurement with seperate measurement nipples for control and manual measurement
The casing of the damper is equipped with a EPDM rubber blade seal conforms to air tightness class C in accordance with EN1751
Blade air tightness class 3 in accordance with EN1751 due to EPDM Seal around the blade
The VAV-damper can be placed in any position in accordance with the airflow direction
Manual measurement of the air flow can be performed without disturbing the control circuit through a separate pressure outlet on the orifice plate of the flow variator
All duct connections have spigot dimensions and are equipped with sealing rings made of rubber
Controls
Controller type GRUNER227VM-024-05 of 5Nm (size 100 up to 500) and GRUNER227VM-024-10 of 10Nm (size 630) are pressure regulated actuators for pressure independent controls and with a digital display which enables monitoring the airflow and setting up values without external equipment
Operating range 0-10V or 2-10V (Standard set on 0-10V)
A simple scewdriver can adjust the settings on site
Units of airflow: l/s or m3/h
