Technical documentation
WKP-O
1. INTRODUCTION
The purpose of technical documentation is to familiarize the user with the intended use, design, operation principle,
installation, periodic maintenance and operation of product.
2. LEGAL REGULATIONS
The WKP-O dampers are certified by CTO Gdańsk, Certificate of Constancy of Performance no. 2434-CPR-
0010.
The WKP-O dampers are designed, manufactured and tested in accordance with the following standards: PN-EN
15650 “Ventilation for buildings – Fire dampers” and PN-EN 13501- 3 “Fire classification of construction products
and building elements – Part 3: Classification using data from fire resistance tests on products and elements used in
building service installations: fire resisting ducts and fire dampers.”
The effectiveness of the dampers is confirmed by tests according to PN-EN 1366-2 “Fire resistance tes ts for service
installations – Part 2: Fire dampers.” The WKP -O fire damper is classified as tightness class C (housing tightness) on
the basis of tests carried out according to PN-EN 1751 “Ventilation for buildings. Air terminal devices. Aerodynamic
testi ng of dampers and valves.”
3. INTENDED USE
WKP-O fire dampers are classified in the following fire resistance range and can be mounted in the following building
partitions:
a. EI 120 (ve i
↔
o) S – horizontal axis of rotation of damper blades. In rigid walls with low density (650±200)
kg/m2 or more, with 125 mm thickness or more and with fire resistant class EI 120 or higher (e.g. concrete,
masonry of solid brick, cellular concrete blocks or airbricks and prefabricated boards),
b. EI 90 (ve i
↔
o) S, E 120 (ve i
↔
o) S – horizontal or vertical axis of rotation of damper blades. In rigid walls with
low density (650±200) kg/m2 or more, with 120 mm thickness or more and with fire resistant class EI90 or
higher (for dampers with horizontal or vertical axis of rotation of damper blades), EI120 or higher (for dampers
with horizontal axis of rotation of damper blades).(e.g. concrete, masonry of solid brick, cellular concrete blocks
or airbricks and boards),
c. EI 120 (ve o
→
i) S – horizontal axis of rotation of damper blades. In standard walls with 125 mm thickness or
more and with fire resistant class EI 120 or higher
where:
E – fire integrity,
I – fire insulation,
S – smoke leakage,
120/90 – duration of fulfilment of E, I and S criteria, expressed in minutes,
ve – damper mounted directly in the wall,
ho – damper mounted directly in the ceiling,
i
↔
o – operating effectiveness criteria are fulfilled from the inside to the outside (fire inside), and from the outside
to the inside (fire outside).
o
→
i – operating effectiveness criteria are fulfilled from the outside to the inside (fire outside)
WKP-O fire dampers may be installed without ventilation duct, from one or two sides with mounted honeycomb mesh
cover.
WKP-O fire dampers may be installed in vertical building partitions with both horizontal and vertical rotation axis
of baffle, with any actuator location.
WKP-O fire dampers are intended for installation on internal and external building partition as also at a distance from
them. In case of external wall installation, use of finishing element is required (intake or exhaust) which will protect
from influence of atmospheric factors. Drive system (actuator) should be installed inside facility. It is recommended to
use dampers in special execution (impregnated fireproof boards, anti-corrosive steel elements).
WKP-O fire dampers may also be installed in building partition of a smaller fire resistance. In this case, the damper`s
fire resistance is equal to the building partition fire resistance, considering the smoke leakage criterion.
