This is a very special fluid that is used in a smoke machine in conjunction with the Freezefog Pro. Molecular Low Fog Fluid is a water-based composition that leaves no oily residue. It is odourless, non-irritating, non-toxic, and non-flammable. It forms a bond with liquid CO2 to produce a completely dry, low-lying fog. This acts in the same way as dry ice fog but without the wet residue. It can be used in all Le Maitre smoke machines to create a thick odourless cloud of fog with a very short hang time. The ash content is low. Suitable for the Freezefog Pro.
