Staircase smoke extraction systems
Polish gravity smoke extraction systems
Staircases have a communication function inside buildings, they also play a very important evacuation function in cases of various types of danger. Equipping the staircase with an effective smoke extraction system makes it possible to carry out rescue operations efficiently and effectively.
Tasks for gravity smoke extraction systems are defined in technical and construction regulations and fire protection regulations. In terms of the protection of escape routes, in this case vertical ones.

Smoke extraction systems for staircases are an important aspect of fire safety in buildings. Advantages of smoke extraction in staircases:
People safety: Smoke extraction in staircases is important to ensure the safety of people in the event of a fire. With the right smoke extraction system, smoke and heat will be removed from the stairwell, allowing people to safely evacuate the building.
Improved visibility: Smoke extraction in staircases improves visibility in the staircase in the event of a fire. This makes it easier and faster for firefighters to reach the source of the fire, and the evacuation of people is more effective.
Damage Limitation: Smoke extraction in staircases helps to reduce damage resulting from fire. Removing smoke and heat from the stairwell reduces the risk of fire spreading to other parts of the building.
Building regulations: In many countries, smoke extraction of stairwells is required by building regulations, which means that every new building must be equipped with an appropriate smoke extraction system.
Maintaining the continuity of the building’s operation: Smoke removal of staircases allows to maintain the continuity of the building’s operation after a fire. Thanks to this, the building can be reused after appropriate repairs and modernization.
The staircase smoke extraction system consists of several elements:
Fans: These are responsible for pulling smoke and warm air out of the stairwell and bringing in fresh air from outside. Fans can be placed on the roof or on the wall of the building.
Ventilation ducts: These are the connections between fans, the staircase and the exterior of the building, through which air flows. Ventilation ducts should be made of durable, fire-resistant materials such as steel or aluminum.
Smoke detectors and temperature sensors: they are used to detect fire in the stairwell and activate the smoke extraction system.
Roof windows or ventilation grilles: allow smoke and warm air to escape to the outside.
Fire doors: allow people in the stairwell to leave the building quickly in the event of a fire.
Smoke extraction system controller: is an electronic device that controls the operation of fans and sensors and activates the system in the event of a fire.
A stairwell smoke extraction system must comply with local fire safety regulations and standards.
A staircase smoke extraction system must meet certain technical parameters to ensure effective and safe evacuation of people in the event of a fire. Here are some of these parameters:
Fan performance: The fans should have sufficient capacity to carry out the entire volumetric airflow in the stairwell in a few minutes. The specific performance of the fans depends on the size and shape of the staircase.
Fire resistance: Components of the smoke extraction system, such as ventilation ducts, must be made of materials with adequate fire resistance to prevent the spread of fire.
Speed of opening roof windows: Roof windows must be designed to open quickly and efficiently to allow for quick removal of smoke and hot air.
Durability of fire doors: Security and panic doors must be designed and constructed in a way that ensures their strength in the event of a fire and ensures that the building can be safely exited.
Sensitivity of smoke and temperature detectors: Smoke and temperature detectors must be properly calibrated to detect even small fires and activate the smoke extraction system at the right time.
Smoke Extraction System Controller: The SHEV system controller must be programmed to adequately control the operation of fans and sensors and to activate the system in the event of a fire.
Staircase smoke extraction systems are essential to ensure safety in the building. We deal with the production, assembly and service of installations. We invite you to familiarize yourself with the details of our offer.
Offer of gravity smoke extraction system for staircases
Smoke extraction system from A to Z
In the event of a fire, staircases act as an escape route. This is often the only escape route, which is why the correct gravitational smoke extraction system for staircases is so important, this is where a high-quality smoke extraction system should be located.
Our smoke extraction systems work well in high and low buildings, which include gravitational and mechanical methods of smoke extraction of staircases.
The system consists of:
- an alarm control panel equipped with batteries,
- smoke detectors,
- manual trigger button,
- wiring with adequate fire and temperature resistance,
- smoke vent,
- aeration hole.
Smoke dampers in the smoke extraction system are selected to the size of the required active surface. Gravitational smoke extraction of staircases is carried out on the basis of an existing design or we prepare it ourselves.
The comprehensive service includes:
- execution of a design in accordance with the regulations and guidelines of the fire brigade,
- making arrangements for the project with the fire protection expert (in accordance with the Regulation of the Ministry of Interior and Administration of 7 June 2010 on fire protection of buildings, other structures and areas),
preparation of documentation for the submission of a building permit (if required), - preparation of a notification to the construction supervision (if required),
supervision of the construction manager, - comprehensive technical assembly by authorized fitters,
connection of the smoke extraction system to the power supply by a licensed electrician, - trial launch of the smoke extraction system in the presence of the customer,
- preparation of subcontracting documentation (if required),
- preparation of documents to be submitted to the construction supervision after the completion of works covered by the building permit.
Why is it worth using gravitational smoke extraction systems from Gulajski?
The owner or user of a building is responsible for the safety of the people in it. Therefore, he is obliged to use smoke extraction in staircases. It should be remembered that in many cases it is the only system in the facility that can save the health or life of the people present in the event of a fire.
The implementation of the staircase smoke extraction system should be entrusted to a professional and reliable company with experience. The person supervising the construction works and the fitters should have the appropriate qualifications. We provide professional execution of works without any deviations from the design. We use proven materials.
Staircase smoke extraction systems are smoke extraction systems necessary to ensure safety in a building. We deal with the production, assembly and service of installations.
We design and manufacture advanced gravity smoke extraction systems
There is a wide group of buildings in which there is a need to use an automatic smoke extraction system for staircases. Its key role is to remove smoke and heat, and thus leave escape routes.
Smoke extraction is possible when the system detects smoke and opens smoke ventilation windows and smoke vents. They are the ones that will escape the smoke, which is a great obstacle in the rescue operation.
When it is removed relatively quickly, people staying in the building will have a chance to leave the building safely.
The price for a staircase smoke extraction system is calculated individually.
Due to the fact that we provide comprehensive services including assembly, creation and installation of the system, our customers incur a one-time cost, without the need to employ several independent companies.
Proper smoke extraction of staircases and other rooms can save many lives. Contact us and let’s talk about our offer – we produce smoke ventilation systems, as well as a number of other functional building materials.
