Constant Airflow Regulator MR
MR Mono - MR Modulo
INTRODUCTION
RANGE
• Aeraulic disturbances within HVAC systems
generate airflow variations.
• Managing to set real airflows as per those
calculated in design stage, will ensure hygiene
(ventilation) and thermal comfort (air conditioning)
while limiting noise and optimizing fan or AHU
operating costs.
2 models:
• MR Mono: 1 code = 1 factory-set airflow
• MR Modulo: 1 code = several airflow set point
(8 references).
7 diameters (mm): 80, 100, 125, 150, 160, 200 and 250.
3 Pressure ranges:
• between 50 and 250 Pa for the standard MR Mono
and the MR Modulo,
• between 150 and 650 Pa for the MR High Pressure,
• between 80 and 250 Pa for the MR Modulo VMT
(compliant with VMT technical approval).
CONSTRUCTION AND MATERIAL
➀Removable clips in PC / ABS plastic,
➁Regulating silicon membrane,
➂Double-lip airtightness seal in elastomer
➃Housing in PC / ABS plastic,
➄Rotating adjustment ring in PC / ABS plastic for
airflow setting.
The following information is directly indicated on the
product:
• Flow direction, diameter in mm and inch, operating
differential pressure range, code, production
traceability,
• MR Mono: factory airflow calibration (both in m³/h)
and cfm),
• MR Modulo: airflow setting range correlation table
(both in m³/h and cfm).

PRINCIPLE OF OPERATION
• CARs (MR) purpose is airflow balancing in HVAC
ductwork.
• It can be easily inserted into a portion of a circular duct
network in order to regulate an accurate and constant
airflow within a large differential pressure range.
• The membrane inflates or deflates depending on the
pressure drop on both sides of the CAR, changing
consequently the free air passage (see illustration
below).
> This principle guarantees a constant airflow when the
upstream/downstream differential pressure varies.

FIELD OF APPLICATION
• Maintaining airflows in ventilation or air conditioning
ductworks.
• Use in air supply and air exhaust.
• Operating airflow range (see diagrams).
• Tolerance in airflow over operating range:
- +/- 5 m³/h for an airflow ≤50 m³/h except VMT MR,
- +/- 10 % for an airflow > 50 m³/h except VMT MR,
- 0/+30% for VMT MR (to ensure compliance with
technical approval).
• Functional differential pressures:
- MR Modulo and standard MR: range between 50
and 250 Pa,
- MR Mono High Pressure: range between 150 and
650 Pa,
- MR Modulo VMT: range between 80 and 250 Pa.
• Temperature range of use: -10 to 60° C.
• Compliant with DIN EN 1506 (dimensions).

ACOUSTIC FEATURES
Sound power levels of noise (Lw) at duct output:
The following tables give the sound power levels of noise (Lw) expressed in decibels per octave (dB/oct) as well as the global sound power levels
in dB(A) according to the pressure drop.
These sound power levels are results of tests carried out by a Dutch independent laboratory (PEUTZ) and are given at the duct outlet.
Measures were carried out in accordance with NF EN ISO 3741 and NF EN ISO 5135 norms, with a CAR fitted into a duct with an upstream and
downstream straight length equal to 3 diameters.

ACOUSTIC FEATURES
Sound power levels of noise (Lw) at duct output:
The following tables give the sound power levels of noise (Lw) expressed in decibels per octave (dB/oct) as well as the global sound power levels
in dB(A) according to the pressure drop.
These sound power levels are results of tests carried out by a Dutch independent laboratory (PEUTZ) and are given at the duct outlet.
Measures were carried out in accordance with NF EN ISO 3741 and NF EN ISO 5135 norms, with a CAR fitted into a duct with an upstream and
downstream straight length equal to 3 diameters.

INSTALLATION
• The MR will push-fit into circular ducts in close proximity to a take-off or a terminal.
• It is important to observe the MR orientation corresponding to the airflow direction indicated on the MR.
• Horizontal / vertical mounting possible.
• In order to avoid acoustic and aeraulic disturbance it is recommended to respect the following distance between the MR and the terminal
(grille / diffuser / inlet):
- in exhaust: D = 1 Ø,
- in supply: D = 3 Ø.

1. Adujst the airflow setting
Rotate the adjustment ring for a tool-free airflow setting until the desired airflow according to the correlation table.
2. Position the MR Modulo
Introduce the MR in the duct according to the arrow which shows
the airflow direction. Minimum straight upstream and downstream
distances must be observed. There is no recommendation regarding
the membane positioning.
3. Product localization
MR Modulo is delivered with a sticker which will be needed to be
manually filled on site (MR diameter and airflow setting) and placed
directly onto the duct to show where the MR Modulo has been
mounted.

INSTALLATION
MAINTENANCE
• MR performances are not altered by clogging, therefore it requires practically no special maintenance.
• If used in an atmosphere where there is a lot of particles, sleeves with inspection window (see MAF page 14) are recommended to allow regular
inspection.
• Clean with soapy water. When cleaning, plug the hole on the plastic body, at the base of the bulb, in order to avoid any blocking of this orifice and
to prevent any liquid or foreign body from passing inside the bulb..

MR MODULO SPECIFICATION TEXT
• CARs will be manufactured from ABS plastic without chlorine. They will provide a constant airflow rate, for use in air conditioning
and ventilation systems. They will include an airflow adjustment system and a regulation system as describe below:
- regulation mechanism with a stainless steel spring and a silicone membrane,
- airflow setting system thanks to an adjustment rotating ring (tool-free).
They provide accuracy in airflow over a differential pressure range between 50 and 250 Pa, of:
• +/- 5 m³/h for airflow ≤50 m³/h,
• +/- 10% for airflow > 50 m³/h.
Installation will be possible in duct and accessories as well independent of orientation.
Positioning and sealing will be ensured by a double-lip seal in elastomer.
Type MR Modulo, Aldes brand.
For certain diameters, the same letter on the ring may correspond to two airflow values.
To enable this, the shim must be inserted or removed .
