Systemair offers round fire dampers with wide product range and sizes for 60, 90 and 120 minutes fire resistance. They are manufactured to comply with latest European Standards EN 1366-2 and EN 13501-3. All fire dampers are designed and certified for EI-S performance conformity. PK-I fire damper units are designed to be imbedded into the horizontal or vertical rigid fire partition walls or vertical flexible fire partition walls. All units as standard are electrical actuator or manual actuator driven.
Fire damper casings are made from galvanized steel sheets and the blades are made from asbestos free calcium silicate boards. Each fire damper has an actuator which can be electrical 24V, 230V or manual.

Function of the fire damper is to stop spreading of fire, flames and smoke. The blade remains in open position until the fuse is broken by reaching 72°C ± 1,5°C. After reaching this temperature blade goes to closed position. Electrical actuators can also close the blade on demand of the BMS system and signals the position to a remote controlled place.
Supply and control unit BKN
Communication units BKS
Fire dampers are installed into the fire safety walls and ceilings and connected directly to the duct.
As standard, all fire dampers are designed and certified to comply with EI-S performance attributes. PK-I fire dampers are intended to be embedded into fire partition walls. Installation of these units is described in the Installation, Operation and Maintenance manual for square and circular fire dampers PP-28_PKIR_PKIS_EKI_PKI2-EX_EN_201403.pdf. As standard, all dampers can be supplied with a manual actuator, optional accessories, e.g. microswitches, electromagnets, or a servo-driven actuator and communication control units. Detailed description regarding individual models can be found in TPI-28_PKIR_PKIS_EN_201403.pdf.
Servomotor-driven Fire Dampers
Fire damper closes the damper blade on demand of the Building Management System or based on a supply voltage interruption in the thermoelectric fuse. Servomotor fitted fire dampers are standardly equipped with an electrothermal fuse which, when having reached or exceeded the ambient temperature of 72°C with a tolerance of ±2°C, activates the servo and closes the damper blade within 20 seconds. According to hnEN 15650 each fire damper must have thermofuse.
Modulated Servomotor-driven Fire Dampers
The servomotor is controlled with a standard signal of DC 0 ... 10 V and moves the damper to the operating position while tensioning the return spring at the same time. The damper is turned back to the safety position by spring energy when the supply voltage is interrupted.
Fire damper casings are made of galvanized steel sheets and the blades are made of calcium silicate boards (asbetstos free).
DV7 stands for fire damper with 230V actuator
DV9 stands for fire damper with 24V actuator
