Introduction to smoke dampers
Gulajski smoke dampers are advanced devices used in gravity fire ventilation systems, which play a key role in protecting buildings against smoke and fire. These mechanisms are essential for the safety of building occupants, and their correct application can significantly improve the effectiveness of evacuation and rescue operations in the event of a fire.

Mechanism of action
Smoke dampers work on the principle of convection, i.e. they use the temperature difference to remove smoke from the inside of the building. In the event of a fire, the flaps open automatically, allowing smoke to escape quickly to the outside, increasing visibility and lowering temperatures, thus facilitating evacuation and rescue operations.
Benefits of use
- Safety: They improve the safety of people in the building by quickly removing smoke.
- Evacuation: They facilitate evacuation by reducing smoke and lowering the temperature.
- Property Protection: They help in maintaining the structural integrity of the building through temperature control.
Applications of Gulajski smoke dampers
Types of buildings
Gulajski smoke dampers can be used in a variety of buildings, such as:
- Residential buildings: Both multi-storey and one-storey.
- Commercial buildings: Warehouses, production halls, shopping malls.
- Public buildings: Schools, hospitals, offices.
Additional functions
Some models of smoke dampers also act as skylights, which allows for natural lighting of rooms and cyclical ventilation, contributing to the improvement of air quality inside the building.
Technical conditions and installation
Gulajski dampers can be installed on a variety of roof coverings, including:
- Bituminous membranes
- Steel Plate
- PVC membranes
The preparation of the mounting holes and the selection of the height of the damper base should be adapted to the thickness of all layers of roofing to ensure their effectiveness.
Basic Assembly Instructions
- Roof slope: Smoke vents should be installed on flat roofs with a slope of no more than 15°.
- Distance between the flaps: It should be at least the sum of the lengths of the flap sides or their diameters, but not more than 20 meters.
- Insulation: It is recommended to use mineral wool insulation with a thickness of 50 mm, class A1 reaction to fire, with a density of at least 150 kg/m³ and a heat resistance of Ri = 1.25 m²· K/W.
Installation recommendations
Proper installation of Gulajski smoke vents contributes to:
- Reducing the building’s fire protection class: This improves its overall fire resistance.
- Increase the permissible fire zones: Allows you to create larger fire zones in buildings.
- Escape route extensions: Improves evacuation safety through more efficient smoke management.
The use of smoke dampers in hotels
Specific requirements of hotels
Hotels, as high-intensity buildings, have specific requirements for fire protection systems. Smoke vents in hotels must be extremely effective to ensure the safety of the large number of people staying on different floors.
Benefits for hotels
- Guest protection: Smoke dampers in hotels allow for quick smoke removal, which is crucial for protecting the health and life of guests.
- Minimize Waste: Rapid smoke removal reduces the risk of property damage and reduces the time it takes to recover from a fire.
- Regulatory compliance: The installation of smoke dampers in hotels helps to comply with stringent fire regulations, which is essential for obtaining the appropriate safety certifications.
Application examples
- Corridors: They facilitate the quick extraction of smoke from passageways.
- Lobbies and lobbies: Increase security in high-traffic areas.
- Staircases: Provide safe escape routes.
Summary
Proper selection and installation of Gulajski smoke vents is crucial to ensure fire safety in buildings, including hotels. The benefits of their use include improved visibility, reduced temperatures, easier evacuation and property protection. Thanks to advanced technical solutions, Gulajski smoke dampers are irreplaceable in modern fire protection systems, providing protection at the highest level.
