M range

Description

The M range of industrial dampers is designed for airflow balancing, control, and shut-off in ventilation systems operating under high pressures and elevated temperatures in demanding industrial and commercial environments. Mechanically reinforced, these dampers can be manufactured in large sizes up to 2490 × 2500 mm as a single module. Manufactured in France and available in several performance classes, the range meets airflow control, frost protection, and shut-off requirements with various airtightness levels in accordance with EN 1751. Thanks to its reinforced construction in galvanized steel, stainless steel, or aluminium, it is particularly well suited to demanding industrial applications requiring high pressure resistance and long-term reliability. The M range is particularly suitable for industrial ventilation systems, complex HVAC networks, and technical process applications requiring excellent mechanical strength and high airtightness performance in accordance with EN 1751.
