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.
