I have one of their V-2000 systems and have found it to be a great addition to my shop. I have a permanent connection to my CNC and a portable hose to connect it to the other machines in my shop. The output air from the V-2000 is quite clean and I have had to clean the filter very infrequently. It's very easy to tell when it's time to clean the filter by checking the pressure gauge.
