Aironn produces motor driven smoke dampers for smoke extraction systems. Smoke dampers are controlled by the motors on them and prevent spreading of high temperature smoke to undesirable parts. Dampers, motors of which are placed in a special protection box are easily accessed for maintenance and control from the aisle. On and off status of damper can be easily observed on the engine through BMS. (???) Body and blades of multi-blade dampers are made of high quality galvanized steel. Motor-driven smoke dampers are produced in any dimensions below 2000 x 2000 mm. Protection Grill is optional in our dampers.
