VAV-RSB • Rectangular VAV dampers

VAV-RSB 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 damper has stable synthetic bearings and its shaft is mounted in maintenance free synthetic headings
  • Airtightness of the casing class C in accordance with EN1751
  • Blade air tightness class 3 in accordance with EN1751 in closed position

Controls

  • Controller type Belimo LMV-D3-MP (5Nm) and Belimo NMV-D3-MP (10Nm) are pressure regulated actuators for pressure independent controls. Settings can be done by using the Assistant App* (smartphone) with NFC connection (Near Field Communication) or by using the service tool ZTH (PC-tool).
  • Operating range 0-10V or 2-10V (Standard set on 0-10V)
  • Units of airflow: l/s or m3/h
  • Minimum adjustable air volume set at air velocity at +/- 2 m/s and maximum adjustable airvolume set at air velocity of 12 m/s
  • Differential pressure range Δp @ Vnom 38 - 500 Pa
  • Running time over the full actuator range : 100s
  • Power consumption 5 Nm: 2W, 3.5VA / 10 Nm: 3W , 5VA
  • Supply voltage 24V AC/DC
* Assistant App available in App Store & Google Play Store
* For iPhone an ZIP-BT-NFC converter is needed!

Options

  • Insulated version VAV-RSB-I, satndard insulation thickness 30mm
  • Other communication types (ModBus, KNX) and other brands of servomotors available on request
  • Airtightness class C available upon request

Accessories

  • Sound attenuator, type BTH-B

Order example

  • VAV-RSB 400 X 100 LXH

  • VAV-RSB = Variable or constant volume damper
  • Q = In-Duct air volume in m³/h
  • Qmin - Qmax = minimum and maximum set point in m³/h
  • Vk = Average velocity in the damper in m/s
  • Ps = Pressure drop over the damper according to the position of the blade
  • Lw [dB/Okt] = Sound power given at a specific pressure drop Ps for the frequencies f[Hz] from 63 up to 8000 Hz in dB
  • Correction factor for other widths in relation to the sizes L=600mm and L=1000mm in dB
