The FDA2-12 round fire dampers are designed for use in general ventilation systems to seal off smoke and fire between adjacent fire partitions. The fire damper blade remains open under normal operating conditions. It is closed shut automatically in the event of a fire.
The entire manufacturing process meets the requirements of EN 15650:2010.
The FDA2-12 fire dampers can be installed in horizontal and vertical fire partitions to provide fire resistance of
EI 120 (ve ho i↔o) S
Designed for round and rectangular ventilation systems,
a return-spring actuator coupled with a thermal trip (in version FDA2-12-M).
The fire dampers can be installed in the following partitions: concrete separing floor, concrete wall, solid brick wall, cellular concrete unit wall, gybsum board wall on steel frame.
The system of single-compartment steel, circular smoke extraction ducts in E600 120 (ho) S1500 single fire resistance class is intended to be used in the construction industry in a horizontal system as elements creating a smoke extraction ventilation system or combined ventilation, fulfilling at the same time the functions of general and smoke extraction ventilation, assuming that they serve only the compartment in which they have been installed. Systems serving one fire compartment may be independent systems or may be combined with a collective, multi-compartment system. The main task of the smoke extraction systems is to remove hot gases and smoke from the area covered by the fire in order to facilitate the evacuation of people and to enable the extinguishing action and the evacuation of people from the area at risk, while complying with the criteria of fire and/or smoke tightness specified under conditions of exposure to a temperature of 600°C.
SMOKE system single-compartment circular smoke extraction ducts have the following application areas:
Smoke extraction ducts are designed for single fire compartments,
The smart solution for air distribution - FLX-REKU system:
The FLX-REKU air distribution ductwork consists of ventilation semi-rigid ducts, distribution and plenum boxes, ventilation dampers and other elements that, together with a heat recovery unit, constitute a complete mechanical ventilation system with heat recovery (MVHR). The FLX-REKU system is a great solution when high durability and flexibility are required. The high circumferential rigidity allows burying the ducts in concrete.
Guaranteed airtight installation - connections with EPDM seals,
We have expanded the range of FLX-REKU system products with silencers, offsets and UPgraded the design of plenum and distribution boxes!!
