At the Chicago Midwinter Dental Show, February 2007, Dean Dental Systems introduced the industries first Variable Speed Dry Vacuum System.  Thanks to variable speed technology and an energy efficient dry vacuum pump, power consumption can be reduced by as much as 70% over wet systems. Add in the elimination of water and sewage costs, and this system can pay for itself in as little as three years. Our technology can save a practice around $20,000 over a ten-year period.
