VAV-CS GRUNER • VAV dampers with actuator

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

  • Sound attenuator, type SAR
  • Water heater, type CWA
  • Electric heater, type CVA

Order example

  • VAV-CS 100 + SAR 100

Explanation:

VAV-CS = Circular Airflow regulator type

100 = Diameter of the damper

SAR 100 = Sound attenuator type
