The dampers consist of blade frames and control mechanisms. It serves to regulate the air flow
by throttling the cross section.
The dampers are intended for atmospheres protected against weather influences with climatic
condition classification of class 3K5 with temperature limitation from -20°C to +50°C, without
condensation, frost, ice, without water, including from other sources than from rain acc. to EN
60721-3-3 zmA2, and for atmospheres with explosion hazard of group and category 2G Ex h IIC
T6…T3 Gb acc. to EN ISO 80079-36.
If the damper is fitted with electrical items, the temperature range shall be restricted acc. to the
temperature range of the electrical items used. Then the group of non-explosiveness of the
damper with electrical items depends on the non-explosive design of the electrical items installed
on the damper. The electrical devices installed together with the damper must be made in the
design corresponding to the given zone. The principle for determining the respective zones
specifies that it shall not be distinguished whether the specified atmosphere is inside or outside
the damper.
68°C T6
98°C T5
140°C T3
The dampers are not intended for air masses with mechanical, dusty, fibrous and sticky admixtures.
• Manual control
• Control for mounting the actuator

The dampers are intended for installation in air-conditioning piping. The operation position is
arbitrary.
The minimum space for the control device is 200 mm (in blade rotation axis).
When assembling round dampers into the piping, respect the overlap of open blade "a" (tab.
4.3.1.).

5
The damper for actuator attachment is fitted with a square pin with 8 x 8 mm
cross section, onto which the actuator is to be fixed either directly or with
the help of a reducer. The pin exceeds the damper flange by 30 mm.

- flanges with 30 mm width are fitted with oval holes in corners
• Round piping with flanges - flanges acc. to EN 12 0505
• Spiro piping with lip seal

The frames, blades and control mechanism of the dampers are made of galvanized or stainless
metal sheet, respectively; the blade pins of square dampers are made of plastic, the blade pins
of round dampers are made of galvanized steel or stainless steel, respectively.
The dampers are delivered without further surface treatment.
• logo of company - manufacturer • serial number • company name and address
• type and design • year of production • size and weight
• number of technical specification • certification
Furthermore, the damper is marked with the symbol of non-explosiveness.
The dampers are transported as bulk cargo in covered means of transport. The dampers can be
transported on pallets or in crating upon accord with the customer. For handling during transport
and storage, the dampers must be protected against mechanical damage. The potential
packages will be considered non-returnable and their price will not be included in the damper price.
Unless another method of reception is specified in the purchase order, the handover of the
dampers to the forwarder shall be understood as reception.
The dampers must be stored in covered buildings, in an environment without aggressive vapours,
gases and dust. A temperature in a range of -5°C and +40°C and a relative humidity of max. 80%
must be maintained in the buildings. For handling during storage, the dampers must be protected
against mechanical damage.
The manufacturer provides a warranty of 24 months from the date of dispatch for the dampers.
If the dampers are damaged by transport, a record must be written down with the forwarder at
reception for later complaint.
The assembly of the dampers must be carried out while observing all applicable safety standards
and regulations.
Before putting the dampers into operation and during subsequent operability inspections, the
following points must be visually checked: correct incorporation of the damper, interconnection of
all metal parts and, if actuator or limit switches are attached, correct connection.
The flange and screw connections must be conductively connected during assembly, for protec-
tion against hazardous contact according to EN 332000-4-41,-4-47 and -5-54. 2 fan-shaped
washers in galvanized design are to be used for conductive connection; they are to be situated
under the head of one bolt and under the screwed nut.
The assembly consists in installation of the damper into the air-conditioning piping.
