VAV-CS GRUNER • VAV dampers with actuator

Circular
Gruner controller

Accessories

TRAFO D • Transformators 230 V / 24 V AC

Datasheet Manual / Quick start-up Manual / Gruner 227VM Technical data / Regulator 5 Nm Technical data / Regulator 10 Nm Certificates / CE

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
Minimum adjustable air volume set at air velocity at +/- 2m/s and maximum adjustable airvolume set at air velocity of 12m/s
Running time over the full actuator range : 100s
Power consumption 2.5W, 4.0VA
Supply voltage 24V AC/DC

Options

Other communication types (ModBus, KNX) and other brands of servomotors available on request
Insulated version VAV-CS-I available upon request, satndard insulation thickness 50mm

Accessories
