Galvanised steel ventilation damper MAX MR

The MR Max is an airflow regulator which ensures a stable airflow that can be adjusted up to high pressure. It can be adjusted on site to control IAQ, comfort and energy savings. on-site adjustment easy to access from outside, wide scope of use: large diameter, high airflow, high pressure, energy savings: stable and low leakage (class C). The MR Max features a spring damper to maintain a constant airflow in the ducting system up to a pressure of 1000 Pa for air supply or extract applications. The airflow setting is adjustable on site from outside the duct using a key. male connector with crimped seals, Class C airtight properties as per EN 1751, airflow tolerance: Q average = Q nominal +/- 10 m3/h for Q nominal ≤ 100 m3/h, Q average = Q nominal +/- 10% for Q nominal > 100 m3/h, operating temperatures: -30°C / +100°C, certified VDI 6022. insulated version (on request) a control device comprising: an aluminium damper a spring and stainless steel pin fitted to PTFE bearings (polytetrafluoroethylene) an adjustment device, made of transparent plastic. possible to adjust nominal airflow from outside using Allen key SW2, directly installed between two circular ducts, installation direction indicated on component, horizontal or vertical installation.
