Stage Plus Smoke Fluid Medium Density in a 5 litre container is a ready-to-use fluid for fog and smoke machines, producing a medium-density smoke that sits between Stage Plus's lighter and heavy grades. Medium density is a common all-round choice when you want visible beams and atmosphere for concerts, clubs, theatre, corporate events and church stages without the thick, lingering clouds a heavy fluid gives. Stage Plus says the fluid is compatible with most smoke machines on the market and offers it in several density levels so it can be matched to the venue and effect. The container label describes it as water-based, odourless, non-toxic and oil-free. It comes in a white 5 L jerry can with a carry handle and screw cap. Check your machine manufacturer's fluid recommendations before use, and follow the label's handling and storage guidance.
