To calculate dental user capacity:

Please note that the user capacity listed for each model is based on typical combinations of high-volume evacuators (HVE), saliva ejectors (SE) and nitrous oxide (N2O) scavengers that can work simultaneously in a conventional dental office setting.  Typically, each HVE equals 1 user, each SE Equals 1/2 user, and each N2O scavenger equals 1/2 user.  User satisfaction is a subjective matter.  Ratings are shown for planning purposes only.  Piping length and configuration can affect vacuum performance.  For specific application, contact Midmark Technical Service for vacuum sizing recommendations.
