The FDA212 round fire dampers are designed for use in general ventilation systems to seal off smoke and fire between adjacent fire partitions. The fire dampers are classified according to EN 135013+A12010P (Fire classification of construction products and building elements). The fire resistance was tested as per PNEN 1366 22015 (Fire resistance tests for service installations — Part 2 Fire dampers). The entire manufacturing process meets the requirements of EN 156502010. The FDA212 fire dampers can be installed in horizontal and vertical fire partitions to provide fire resistance of EI 120 (ve ho i↔o) S (which may depend on the actual fire resistance of the partition). The fire dampers are available in the nominal diameter sizes DN200, DN224, DN250, DN280, DN300, DN315, DN355, DN400, DN450, DN500, DN560, DN600, DN630. All fire dampers have a torsion spring trip (in FDA212T) or a returnspring actuator coupled with a thermal trip (in FDA212M).

The standard duct length is 3000 mm; the sheet thickness for a given diameter is the same as that for the SPR spiral coiled ducts. The ducts of diameter 250 mm or greater feature outer ribbing to improve the robustness and vacuum pressure strength.

The IPR access door features a CR EPDM gasket and it is designed for installation on round duct walls. The design of the IPR access door and its gasket profile provide a perfect seal around the duct opening. This ensures a high air tightness class. The product provides a very simple, lowcost and extremely effective solution for closing and sealing access openings in the ductwork. The openings made in the ductwork for access doors must be sized to meet the requirements of EN 12097. Another determinant of the access opening size is how the interior is cleaned. Some cleaning processes and tools require access doors as large as 800x400 mm. The access door is installed in the opening made using the cutting template supplied with the product.
