Stage Plus Smoke Fluid Heavy Density in a 5 litre container is a ready-to-use fluid for fog and smoke machines, formulated to produce dense, heavy smoke for strong visual effects on stage. The heavy-density grade is chosen when you want thick clouds that fill a stage or dance floor and linger, for concerts, clubs, theatre productions, haunted attractions and special effects. Stage Plus offers its smoke fluid in several density levels so users can match the effect to the venue. According to the product label it is a water-based formulation of osmosis water and glycol, odourless, non-toxic and oil-free, and made in Europe, with safety and usage information printed in English, French and Spanish. The retailer description says it works with most fog machines on the market; check that your machine is designed for water/glycol-based fluid and follow its maintenance guidance, and be mindful of smoke detectors in the venue. It comes in a 5 L jerry can with carry handle. Stage Plus is AV Distribution's South African brand.
