Specifications: Dimensions: 23 * 17.5 * 8.2cm Total Weight: 2kg tank capacity: 0.3 liters spray height: 1-2 m Material: Stainless steel boot to produce smoke heating time (mins): 5 maximum amount of smoke output duration (mins ): 1-2 heating power (W): 700 smoke output speed: 2000 ft3 / min fuel speed: 60 minutes /0.3L main features: manual, remote control can be operated. The LD-700I by technological means the aerosol is atomized into 1-2 micron particles, forming thick white smoke we have seen, it is small particles, suspended air, smoke can be maintained for about 30 minutes, then slowly fades eventually go away, will be left without precipitation, achieve excellent air flow and ventilation detection. They use to meet international food-grade aerosol particle smaller, thicker smoke, safe non-toxic residue, in cleanroom, pharmaceutical, food plants can be assured!
