The Antari 515 1500 Watt fogger is one the most demanded from professionals. Ideal for very large venues, outdoor events, movie production and many other applications. The precision lies with optoelectronic liquid sensor (OPTO). When sensing there’s insufficient liquid, the pump will stop working, and then the production of fog will be ceased until it senses the re-filling of the liquid again. LCD digital control modules are equipped to W-515 & W-530 allowing the users to set the volume control, timer control, and DMX functions to precision.
