Product presentation CU2/B
The CU2/B damper is a battery assembly of several CU2 dampers with maximum 4 individual dampers (B12, B21 or B22) and with a
fire resistance up to 120 minutes. The CU2/B battery assembly is the ideal solution for installations with large dimensions.
Fire dampers are installed where air ducts penetrate fire-resistant compartment walls. Their role is to restore the fire resistance grade
of the penetrated wall and to prevent smoke propagation. Fire dampers are distinguished by their degree of fire resistance, by their
aeraulic properties as well as by their installation ease. Rf-Technologies’ fire dampers are all CE marked. They can be equipped with
various types of mechanisms depending on the specific needs linked to the project or to the local regulations.

10 Storage and handling
Storage and handling
As this product is a safety element, it should be stored and handled with care.
Avoid:
• any kind of impact or damage
• contact with water
• deformation of the casing
It is recommended:
• to unload in a dry area
• not to flip or roll the product to move it
• not to use the damper as a scaffold, working table, etc.
• not to store smaller dampers inside larger ones
Installation
General points
∎The installation must comply with the installation manual and the classification report.
∎Axis orientation: see the declaration of performance.
∎Avoid obstruction of adjoining ducts.
∎Product installation: always with closed damper blade.
∎Verify if the blade can move freely.
∎Please observe safety distances with respect to other construction elements. The operating mechanism must also remain
accessible: allow for a clearance of 200 mm around the housing.
∎The air tightness class will be maintained if the damper is installed according to the installation manual.
∎Rf-t fire dampers are always tested in standardised constructions according to EN 1366-2. The achieved results are valid for similar
supporting constructions with a fire resistance, thickness and density equal or superior to the supporting construction used
during the test.
∎The damper must remain accessible for inspection and maintenance.
∎Schedule at least 2 visual checks each year.
