The CONCEPT SMOKE PERSISTENT SMOKE is a specific type of smoke fluid produced by a company called Concept Smoke Systems. This fluid is designed for use in their professional-grade smoke and haze machines, particularly the Spirit 900.

Key Features

• Persistent Smoke: S/FLUID-A is formulated to produce a very persistent, long-lasting smoke effect. The smoke is non-toxic and has a consistent particle size of 0.2 to 0.3 microns. At room temperature (20∘ C), the smoke can hang in the air for approximately 1 to 1.5 hours.
• Composition: The fluid is a water-based mixture primarily composed of pharmaceutical-grade mono-propylene glycol or glycerine and deionized water.
• Safety: It is considered safe and non-toxic under normal conditions of use. The Material Safety Data Sheet (MSDS) for the product indicates low oral toxicity and low hazard by inhalation due to its low vapor pressure.
• Specific Use: S/FLUID-A is just one of several fluid types offered by Concept Smoke Systems. The company also produces "Fluid B" for quick-dispersing smoke and "Fluid C" for a medium-dispersing effect. The choice of fluid type depends on the desired visual effect and the application. The machines themselves may need to be reprogrammed to work with a specific fluid type.
