Technical Specifications

The product is intended for use in enclosed spaces with ambient air temperature from +1°C to +45°C and relative humidity up to 80%. The damper is designed for operation in moderate (P) climate regions, placement category 3, according to DSTU 15150-69.

КПД and КПДУ dampers are manufactured in two modifications: with an electromagnet (can be installed vertically or horizontally) and with an actuator (installation orientation is independent of spatial orientation). The operating position of the dampers can be any in space. Characteristics are maintained with both vertical and horizontal damper blade orientation. Dampers are available in wall-mounted or ducted versions. They can be supplied with one or two flanges.

Structure and Principle of Operation

The manufacturer reserves the right to install various actuators that ensure the stated technical parameters of the dampers.

In the closed position, the damper ensures tight contact of the blades with the housing's seating surfaces. The housing is the main load-bearing structure of the damper, with one or two connection flanges on its end surfaces (depending on the version).

The smoke exhaust damper is closed in its normal (standby) position, with its blades flush with the passage cross-section.

When power is supplied to the electromagnet, the blade opens via a spring, after which a limit switch breaks the circuit and disconnects the electromagnet from the power supply. The blade returns to its initial position manually.

In the actuator version, the blade automatically moves to the normal (standby) position when power is supplied to the actuator. In case of fire, a control signal from fire alarms, automatic fire suppression systems, or other sources de-energizes the actuator, and its return spring moves the damper to the open position. The position of the blades can be monitored via indicator lights connected to the actuator's contacts.

If the power supply is disconnected (not due to fire) and then reconnected, the damper blades automatically return to the normal (standby) position.

In the two-wire control version, the damper blades are moved to the OPEN or CLOSED position by an external control signal that applies voltage to the actuator's terminals.

Additional Options

Additional equipment for installation is sold separately and can be purchased at the customer's request.

Smoke Exhaust Grille RD

The smoke exhaust grille can be used to fully cover the internal cavity of the damper from external view, especially where strict decorative requirements are absent. It also protects the damper and its actuator from unauthorized access. The grille features one row of fixed 45° air louvers. It can be made of galvanized steel, carbon steel with special coating (M), stainless steel (N), or aluminum.

Anti-Vandal Mesh

Used to protect the actuator from possible external influences.

Decorative Aluminum Grille

For enhanced design requirements, a decorative grille made of aluminum can be supplied. It also features fixed 45° louvers and is treated with polymer coating or anodized for atmospheric protection.

Mounting Frame

Facilitates damper installation in wall openings, provides additional rigidity, and prevents damper deformation during mounting. Installation is done directly with self-tapping screws to the mounting frame flange.

Installation and Connection

⚠️ Before installation, ensure the housing is free of foreign objects, such as film or paper.

⚠️ During installation, ensure minimal access to the unit for servicing or repair.

Dampers are not intended for installation in air ducts and channels of premises with fire and explosion hazard categories A and B, in local exhaust systems for removing fire hazardous mixtures, or in systems containing media aggressive to ordinary carbon steels, or media with sticky and fibrous materials.

Fire dampers are intended only for installation in systems that are regularly cleaned to prevent the formation of combustible deposits.

Installation of the damper in a fire-resistant enclosing structure must be carried out according to DBN V.1.1-7-2003. The fire resistance of the seal must not be lower than that of the enclosing structure.

Installation Recommendations:

• For Vertical Structural Elements: Diagrams show mounting configurations for vertical walls and shafts, indicating clearance requirements and the use of sealing materials.
• For Horizontal Structural Elements: Diagrams illustrate mounting in horizontal structures like ceilings, showing placement and clearances.
• For Ducted Installation: Diagrams depict installation within air ducts, showing connections and required space.

Important Note on Installation: When preparing the damper for installation, it is crucial to brace the damper housing with wooden spacers to prevent possible warping, twisting, or deformation of the housing geometry, which could lead to blade jamming and loss of functionality. After the damper is built into the smoke shaft, fire wall, or ceiling, and the sealant has fully cured, remove the wooden spacers. The blades should then open freely without friction.

Ground the damper, connect the electromagnet or actuator (depending on the model) to the automatic fire suppression system, and test the damper's operation.
