AmericanDJ F1L Premium

ADJ F1L Premium is a one-litre bottle of water-based fog fluid, formulated for ADJ fog machines and usable in any other water-based machine.

One litre is the size to keep as a spare in the case rather than the bulk supply for a season, so the machine never sits dry at the one gig where you needed it. ADJ catalogues it under Fluid, Timer and Accessories as part number F1L Premium.
