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
