Concept Smoke Screen generators lend themselves particularly effectively to ducted applications.The class leading particle size of the fog generated ensure very little particle collision in the tube of the duct. When fog particles collide, there is a danger that droplets can form, yet with an E+ generator, and correct installation, this risk is eliminated. Ducted runs are used very succesfully to protect runs of adjacent offices, long glass walls and aisles of racking within warehouses
