Self-actuating backflow protector EKO-BSV
is installed in the supply air duct in a FT or
FTX system to prevent the spread of smoke.
The exhaust air system must be dimensio-
ned to be able to evacuate smoke. Both the
supply air and the exhaust air fan must be
in operation throughout the entire fire. The
protector closes quickly in the event of a
fire that generates an overpressure in the
fire cell. It is fully self-actuating and does
not need to be connected to a monitoring
system. Self-actuating backflow protec-
tor EKO-BSV is designed so that it can
withstand high temperatures, which means
that it can also be placed inside the fire cell
itself. Mounting can be done horizontally or
vertically in a fire cell, in a shaft or in a cor-
ridor in such a way that it can be inspected
and cleaned.
The fire properties are tested according to
the same test standard as for CE marked
Fire Damper. Fire properties corresponding
to E90 applies provided that EKO-BSV is
mounted in a duct outside the fire-exposed
fire cell, applies to both wall and floor.
When EKO-BSV is placed outside the ser-
ved fire cell it does not need to be depres-
surized.
Ventilation ducts and components are sus-
pended, installed and insulated in accordan-
ce with current requirements in BBR. When
insulating, the inspection requirement of the
product must be taken into account.
Mounting in ventilation duct
EKO-BSV must be mounted in the supply
air duct so that the arrow on the label points
in the same direction as the air flow (supply
air direction).
