really depends on how many dirty parts you put into it, and how often you use it. Suppose you consider purchasing an UltraSonic LLC 3200FA, our high-performance 65-gallon workhorse, and one of our most popular ultrasonic cleaning machines. Let’s outline your costs. The purchase price on that 3200FA is $15,000. Conversely, for a five-year lease, the monthly payment is about $310 per month, give or take a few dollars.Next, estimate approximately $90 per month to properly maintain the 3200FA. Figure an additional $90 per month for disposal of the used water and the contaminants removed from your parts during the ultrasonic cleaning process. And finally, add $50 per month for the electricity needed to power the 3200FA (that’s probably a high figure, but to be fair, we want to err on the high side)
