The American DJ Fog Fury Jett is a high-velocity fog machine that uses red, green, blue, and amber LEDs to add color to blasts of fog over 25' in the air. The machine has a 0.8 gal tank that can be mounted in the front or rear of the unit so that it can be used vertically or horizontally. Fog output is 20,000 ft3/min and ADJ employs Electronic Thermo Sensing Technology to maintain constant temperature to avoid long warm-up times between blasts. Dimensions: 20x10x15 Weight: 17lbs
