MR / MK

Description

The MR/MK range of industrial dampers is designed to withstand extreme airflow conditions in industrial installations operating under high pressures and elevated temperatures. Thanks to their reinforced construction, these dampers provide airflow control, shut-off, and balancing functions for the most demanding industrial ventilation systems.

The range is available in two versions:

• MR: Reinforced industrial damper
• MK: Reinforced high-pressure industrial damper

Available in airflow control, frost protection, or shut-off configurations, the MR/MK dampers are designed for demanding industrial applications requiring excellent mechanical strength, high airtightness, and compatibility with high-pressure and high-temperature operating conditions.

Manufactured from galvanized steel and 304L / 316L stainless steel, the dampers are suitable for use in industrial furnaces, chemical plants, tunnels, power generation facilities, and industrial HVAC systems.
