you will undoubtedly at some point read in some machine manual how you must USE THE MANUFACTURES FOG FLUID OR IT WILL VOID THE WARRANTY OR CAUSE MASSIVE WIDESPREAD DISEASE IF YOU DONT (NOT THAT BAD).  
 
THERE are SOME MANUFACTURES THAT CLAIM TO "CALIBRATE" THEIR FOG MACHINES TO USE THEIR FLUID, while some of this may be true to a degree, the CHEMICAL composition IS WHAT makes A FLUID compatable with a particular machine.  MORE SPECIFICALLY ITS BOILING POINT OR FLASH VAPORIZOATION TEMP is what dictates if a fluid will work properly or not.  , for the most part, the heaters are set to a range OF TEMPS THAT WILL EFFECTIVELY VAPORIZE most brands of THE FLUID that have the same checmical makeup.  

MOST MACHINES ARE HEATED ENOUGH TO VAPORIZE MOST FLUIDS ON THE MARKET, ESPECIALLY THOSE WHICH HAVE TRIETHYLENE GLYCOL IN THEIR CHEMICAL LINEUP.  YOU WILL KNOW IF A FLUID IS NOT COMPATIBLE IF YOU GET SPUTTERING OF HOT UN-VAPORIZED FLUID COMING OUT THE NOZZLE OR A HORRIBLE EYE-BURNING SMELL IF THE FLUID GOT BURNED BY TOO HIGH OF A TEMPERATURE. 

LUCKILY MOST MACHINES OPERATE IN A RANGE OF TEMPERATURES THAT WILL VAPORIZE MOST FLUIDS of a specific type ON THE MARKET. 

OUR PROFESSIONAL LINE OF FOG AND HAZE FLUIDS ARE UNIVERSAL IN FORMULATION SO THEY MAY BE USED WITH ALMOST ALL GLYCOL-BASED MACHINES ON THE MARKET.  If your machine needs to heat up to work then its a glycol/water based machine SO MOST FLUIDS WILL WORK WITHOUT ANY RISK OF DAMAGING THE MACHINE. 

BOTTOM LINE:  DON'T BE FOOLED BY THE MANUFACTURER'S MARKETING ATTEMPT TO CLAIM THAT IF YOU DON'T USE THEIR FLUID THE WARRANTEE WILL BE VOIDED. THIS IS JUST PLAIN SILLY. IT'S NOT THE REAL WORLD AND IF A COMPANY DOES MAKE THIS WARNING. MOVE ON TO ANOTHER BRAND WHO WON'T.  THERE ARE PLENTY OUT THERE WHO STAND NEXT TO THEIR PRODUCTS REGARDLESS OF WHOSE FLUID YOU USE.
