The flow regulator RDR is an element placed inside the duct in order to obtain a constant flow within a pressure range from 50 to 250 Pascals.

It is used in air conditioning or ventilation systems either in extraction or blowing mode.

Important

Important

 N/A
  • Self-adjusting on the pressure range 50 to 250 Pa
  • Easy adjustment
  • The requested air flow is fixed by a screwdriver
  • Made in plastic material (classified Ml) and in galvanized steel for sleeves in 160 to 250 mm
  • Use with a maximum temperature of 60 °C

Presentation

Presentation

 N/A The self-adjusting flow regulator RDR can be adjusted on sites according to the requested air flow.

The marks on the sides of the opening indicate the settings.

Adjustment

Adjustment

 N/A Before setting the regulator, it's necessary to calibrate the flow:
  • Unscrew of 1/4 tour with a screwdriver
  • Adjust the mark to the requested flow
  • Screw according to the air flow

Installation

Installation

 N/A The flow regulators are simply fitted into vertical or horizontal ducts. On the horizontal duct, respect the mention «DOWN» indicated at the front of the product. A leap seal ensures the airtightness.

When the flow regulator is associated with a diffuser, the minimum distance between the diffuser and the regulator is at least one Ø in extraction mode and 3 Ø in blowing mode.

When installing, do not touch the piece of regulation.

Maintenance

Maintenance

 N/A The flow regulator must remain accessible to permit its maintenance.

Characteristics

Characteristics

 N/A The curves show the flow variations in m³/h of RDR Ø 150, 160 and 200 mm in extraction according to the difference of pressure in Pascal (pressure range of 50 to 250 Pa). The values given are averages which may vary of:
  • + or - 3 m³/h for Air Flow < 50 m³/h
  • + or - 5 % for Air Flow > 50 m³/h
Flow regulators are characterized by their noise level in dB(A).
