MR Mono & Modulo – Constant airflow MR Mono & Modulo – Constant airflow
*Out of the scope of ecodesign 327/2011 and ecodesign 1253/2014 regulations because of max power <30W.

MR Mono & Modulo – Constant airflow

  • Provide a pre-set constant airflow on the network, whatever pressure changes occur.
  • Simple to install (no tools needed).
  • Easy to adjust airflow using tool-free rotating ring (MR Modulo).
  • Optimum control (precise, stable, silent and sustainable).
  • Available in just 8 product references (MR Modulo).
  • PVC-free and no maintenance required.
  • UL certification.
  • MR MONO model : single airflow for one product.
  • MR MODULO model : several airflow settings for one product.
  • Plastic body (M1 fire class) housing the silicone control membrane in a calibrated passage width.
    The passage width is fixed for the MONO model and adjustable for the MODULO model.
  • Retention and air tightness provided by a peripheral elastomer external double-lip seal.
  • Diameter : from 80 to 250 mm.
  • Operating pressure :
    • Standard range : in the range between 50 and 250 Pa, airflow from 15 to 650 m3/h (MONO), from 20 to 650 m3/h (MODULO)
    • High pressure range : in the range between 150 and 650 Pa, airflow from 120 to 1100 m3/h (MONO)
  • Airflow tolerance on its operating pressure range :
    • Q average = Q rated +/- 5 m3/h for MR ≤ 50 m3/h
    • Q average = Q rated +/- 10 % for MR > 50 m3/h
  • Operating temperature : -10 °C / +60 °C.
  • Fitted directly in a circular duct or a standard accessory connection.
  • Manual tool-free control of desired airflow by removing wedge and turning rotating ring (MODULO model only).
  • Airflow stabilisation distance :
    • Exhaust : 1 Ø between the terminal and the MR positioned downstream
    • Air supply : 3 Ø between the MR positioned upstream and the terminal
