The Fogmaster Micro Jet ULV Fogger 7401 only has a 1-gallon tank on it so it takes about 30 minutes for the tank to empty. We would suggest you put a timer on it to stop after 30 minutes. It will not hurt the unit, but there is no point in it running longer than normal. You should not allow the fogger to run with no liquid inside the tank.
The manufacturer states that the Fogmaster Micro Jet ULV Fogger 7401 cannot be used with this type of chemical as it would degrade the brass inside the unit.
You can order the Fogmaster Micro Jet ULV 7401 in 220V with us over the phone at 866-581-7378. In the meantime, we do sell the the Commander Tri-Jet Fogger available in 220V on our website.
We apologize but we currently do not ship internationally. Sorry for any inconvenience.
