The multi-blade fire damper type BSK-J/EI90(G) is used to prevent fire and reduce smoke spreading
from one fire compartment to another through the air ductwork system which may penetrate fire
separating walls and floors.
According to standard EN 1336-2 they assure
minimum
90 minutes reliable closing.
The multi-blade fire damper can mounted in vertical (in/on rigid and light walls) or horizontal (in/on
floor) position.
