Recommended areas
of application

SF 4000 X has been developed for spaces where there is frequent smoking, such as offices, hotels, conference centers, healthcare facilities, and shopping malls. Our smoking cabins are all designed with non-smokers in mind, protecting them from secondhand smoke, as well as creating a pleasant indoor environment free from odors. In shopping malls, hotels, and casinos, you often have to leave the premises to smoke. In workplaces, smoke breaks are often quite long since the smokers have to get to a designated smoking area. These types of challenges are easily solved with our smoking cabins, enabling increased work efficiency and more time in commercial areas.

By using SF 4000 X in spaces where there is frequent smoking, non-smokers are protected from secondhand smoke. The indoor air quality is also improved and odors are eliminated, making the environment much more pleasant to stay in. SF 4000 X captures the smoke before it’s able to spread, removing odors, harmful gases and particles through a multi-stage filtration system before releasing cleaned air back into the room. This protects non-smokers from harmful particles and unpleasant odors and allows smokers and non-smokers to stay in the same place, creating a better social environment. The issue of having to walk far distances to get to designated, safe smoking areas is eliminated, which in turn makes smoke breaks shorter and safer, increasing productivity. SF 4000 X is equipped with our fireproof ash handling system and is suitable for any environment that struggles with the challenges associated with frequent smoking.

how it works sf 4000 x

The technology behind the solution

1. Capturing the smoke

A smoke free environment can on only be created if the polluted air is captured before it spreads. The SF-Line makes this possible and the strategically placed air inlets, above the table, send the polluted air into our powerful, multi-stage air filtration system.

2. Filtration of gases, particles and odors

Through multiple highly efficient HEPA 14, ePM1 65% (F7), and activated carbon filters, the tobacco-specific gases, particles and odors are captured and removed from the air.

3. Cleaned air is returned to the environment

After the air has been cleaned of gases, particles, and odors, it is returned into the room, without any detectable traces of cigarette smoke.

3. Fireproof ash handling system

Our unique, fireproof ash handling system (AHS) handles the disposal of ashes and cigarette ends. A patented valve solution keeps it airtight to avoid smoke residue commonly found in traditional ashtrays.
