Rectangular and circular fire dampers CONTENTS Description 2

Rectangular and circular fire dampers Description SCFR-PD with motor KOOLAIR rectangular fire dampers, models SCFR-PD, SCFR-GD, SFR3K1GT and circular fire dampers, models SCFC-PD and SCFC-GD, are approved in accordance with the Technical Building Code according to test standard UNE EN 1366-2 and classified according to EN 13501-3. Fire dampers close automatically to prevent fire and smoke from spreading through ventilation ductwork to adjacent fire compartments. The frame consists of a single sheet of sheet metal with an internal recess reinforced by a slot sheet metal support that prevents a...

Circular fire dampers CE Marking Koolair fire dampers carry the CE marking in compliance with RPC-305/2011/EU, according to EN15650:2010. The SCFR-PD, SCFR-GD, SCFC-PD and SCFC-GD models are certified under NF (NF264 Certification Standard, NF S 61-937-5 fire dampers). The dampers are approved in accordance with European Test Standard UNE-EN 1366-2 and European classification standard UNE-EN 13501-3, where: (E) Integrity (I) Isolation (ho) Installed in Horizontal slab. Mounted in horizontal enclosure. (ve) Installed in wall or stud wall. Mounted in vertical enclosure. (i ↔ o) Symmetric (independent...

Series SF Installation Fire dampers are part of a building’s fire safety system and therefore special care must be taken with their installation. To install the dampers a perforation in the wall that is 100 mm greater than the nominal dimensions of the damper is required. No additional space is required for the mechanism box as it sits outside the wall or partition. As such, when the fire damper blade is in the closed position, it will be exactly vertical in the firewall, as if it were an extension of this wall, as required by UNE-EN 1366-2. Likewise, the dimensions indicated on the drawings...

Installation Precautions during assembly The slot section of the damper frame must be sealed in when fitted both horizontally or vertically. There is an option to use fixing lugs fitted on the damper frame for installation in slab. Arrangement of damper and building elements according to DB-SI (CTE). The following conditions apply to horizontal and vertical dampers: - There must be a minimum separation of 75 mm between fire dampers and building elements. - There must be a minimum separation of 200 mm between fire dampers.
