The constant volume regulator 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 in of pressure in Pascal (pressure range of 50 to 250 Pa). The values given are averages which may vary of 5 % either way. Flow regulators are characterized by their noise level dB(A).
